considering that users don't interact with MariaDB vector search directly, but primarily use AI frameworks, we should use names familiar to vector store connector writers and for AI framework users. That is industry standard M and ef. mhnsw_cache_size -> mhnsw_max_cache_size mhnsw_distance_function -> mhnsw_default_distance mhnsw_max_edges_per_node -> mhnsw_default_m mhnsw_min_limit -> mhnsw_ef_search inside CREATE TABLE: max_edges_per_node -> m distance_function -> distance

|
The following options may be given as the first argument:
|
|
--print-defaults Print the program argument list and exit.
|
|
--no-defaults Don't read default options from any option file.
|
|
The following specify which files/extra groups are read (specified before remaining options):
|
|
--defaults-file=# Only read default options from the given file #.
|
|
--defaults-extra-file=# Read this file after the global files are read.
|
|
--defaults-group-suffix=# Additionally read default groups with # appended as a suffix.
|
|
|
|
--allow-suspicious-udfs
|
|
Allows use of user-defined functions (UDFs) consisting of
|
|
only one symbol xxx() without corresponding xxx_init() or
|
|
xxx_deinit(). That also means that one can load any
|
|
function from any library, for example exit() from
|
|
libc.so
|
|
--alter-algorithm[=name]
|
|
Unused. One of: DEFAULT, COPY, INPLACE, NOCOPY, INSTANT.
|
|
Deprecated, will be removed in a future release.
|
|
--analyze-sample-percentage=#
|
|
Percentage of rows from the table ANALYZE TABLE will
|
|
sample to collect table statistics. Set to 0 to let
|
|
MariaDB decide what percentage of rows to sample
|
|
-a, --ansi Use ANSI SQL syntax instead of MariaDB syntax. This mode
|
|
will also set transaction isolation level 'serializable'
|
|
--auto-increment-increment[=#]
|
|
Auto-increment columns are incremented by this
|
|
--auto-increment-offset[=#]
|
|
Offset added to Auto-increment columns. Used when
|
|
auto-increment-increment != 1
|
|
--autocommit Set default value for autocommit (0 or 1)
|
|
(Defaults to on; use --skip-autocommit to disable.)
|
|
--automatic-sp-privileges
|
|
Creating and dropping stored procedures alters ACLs
|
|
(Defaults to on; use --skip-automatic-sp-privileges to disable.)
|
|
--back-log=# The number of outstanding connection requests MariaDB can
|
|
have. This comes into play when the main MariaDB thread
|
|
gets many connection requests in a very short time
|
|
(Automatically configured unless set explicitly)
|
|
-b, --basedir=name Path to installation directory. All paths are usually
|
|
resolved relative to this
|
|
--big-tables Old variable, which if set to 1, allows large result sets
|
|
by saving all temporary sets to disk, avoiding 'table
|
|
full' errors. No longer needed, as the server now handles
|
|
this automatically. Deprecated, will be removed in a
|
|
future release.
|
|
--bind-address=name IP address to bind to. Several addresses may be
|
|
specified, separated by a comma (,)
|
|
--binlog-alter-two-phase
|
|
When set, split ALTER at binary logging into 2
|
|
statements: START ALTER and COMMIT/ROLLBACK ALTER
|
|
--binlog-annotate-row-events
|
|
Tells the master to annotate RBR events with the
|
|
statement that caused these events
|
|
(Defaults to on; use --skip-binlog-annotate-row-events to disable.)
|
|
--binlog-cache-size=#
|
|
The size of the transactional cache for updates to
|
|
transactional engines for the binary log. If you often
|
|
use transactions containing many statements, you can
|
|
increase this to get more performance
|
|
--binlog-checksum=name
|
|
Type of BINLOG_CHECKSUM_ALG. Include checksum for log
|
|
events in the binary log. One of: NONE, CRC32
|
|
--binlog-commit-wait-count=#
|
|
If non-zero, binlog write will wait at most
|
|
binlog_commit_wait_usec microseconds for at least this
|
|
many commits to queue up for group commit to the binlog.
|
|
This can reduce I/O on the binlog and provide increased
|
|
opportunity for parallel apply on the slave, but too high
|
|
a value will decrease commit throughput
|
|
--binlog-commit-wait-usec=#
|
|
Maximum time, in microseconds, to wait for more commits
|
|
to queue up for binlog group commit. Only takes effect if
|
|
the value of binlog_commit_wait_count is non-zero
|
|
--binlog-direct-non-transactional-updates
|
|
Causes updates to non-transactional engines using
|
|
statement format to be written directly to binary log.
|
|
Before using this option make sure that there are no
|
|
dependencies between transactional and non-transactional
|
|
tables such as in the statement INSERT INTO t_myisam
|
|
SELECT * FROM t_innodb; otherwise, slaves may diverge
|
|
from the master
|
|
--binlog-do-db=name Tells the master it should log updates for the specified
|
|
database, and exclude all others not explicitly mentioned
|
|
--binlog-expire-logs-seconds=#
|
|
If non-zero, binary logs will be purged after
|
|
binlog_expire_logs_seconds seconds; It and
|
|
expire_logs_days are linked, such that changes in one are
|
|
converted into the other. Possible purges happen at
|
|
startup and at binary log rotation
|
|
--binlog-file-cache-size=#
|
|
The size of file cache for the binary log
|
|
--binlog-format=name
|
|
The binary logging format the master will use: ROW for
|
|
row-based binary logging (safer), STATEMENT for
|
|
statement-based binary logging (smaller binary logs),
|
|
MIXED for statement-based binary logging when it's safe
|
|
with fall back to row-based otherwise
|
|
--binlog-gtid-index Enable the creation of a GTID index for every binlog
|
|
file, and the use of such index for speeding up GTID
|
|
lookup in the binlog
|
|
(Defaults to on; use --skip-binlog-gtid-index to disable.)
|
|
--binlog-gtid-index-page-size=#
|
|
Page size to use for the binlog GTID index
|
|
--binlog-gtid-index-span-min=#
|
|
Control sparseness of the binlog GTID index. If set to N,
|
|
at most one index record will be added for every N bytes
|
|
of binlog file written, to reduce the size of the index.
|
|
Normally does not need tuning
|
|
--binlog-ignore-db=name
|
|
Tells the master that updates to the given database
|
|
should not be logged to the binary log
|
|
--binlog-large-commit-threshold=#
|
|
Increases transaction concurrency for large transactions
|
|
(i.e. those with sizes larger than this value) by using
|
|
the large transaction's cache file as a new binary log,
|
|
and rotating the active binary log to the large
|
|
transaction's cache file at commit time. This avoids the
|
|
default commit logic that copies the transaction cache
|
|
data to the end of the active binary log file while
|
|
holding a lock that prevents other transactions from
|
|
binlogging
|
|
--binlog-legacy-event-pos
|
|
Fill in the end_log_pos field of _all_ events in the
|
|
binlog, even when doing so costs performance. Can be used
|
|
in case some old application needs it for backwards
|
|
compatibility. Setting this option can hurt binlog
|
|
scalability
|
|
--binlog-optimize-thread-scheduling
|
|
Run fast part of group commit in a single thread, to
|
|
optimize kernel thread scheduling. On by default. Disable
|
|
to run each transaction in group commit in its own
|
|
thread, which can be slower at very high concurrency.
|
|
This option is mostly for testing one algorithm versus
|
|
the other, and it should not normally be necessary to
|
|
change it. This variable is deprecated and will be
|
|
removed in a future release. Deprecated, will be removed
|
|
in a future release.
|
|
(Defaults to on; use --skip-binlog-optimize-thread-scheduling to disable.)
|
|
--binlog-row-event-max-size=#
|
|
The maximum size of a row-based binary log event in
|
|
bytes. Rows will be grouped into events smaller than this
|
|
size if possible. The value has to be a multiple of 256
|
|
--binlog-row-image=name
|
|
Controls whether rows should be logged in 'FULL',
|
|
'FULL_NODUP', 'NOBLOB' or 'MINIMAL' formats. 'FULL',
|
|
means that all columns in the before and after image are
|
|
logged. 'FULL_NODUP', means that all columns are logged
|
|
in before image, but only changed columns or all columns
|
|
of inserted record are logged in after image, 'NOBLOB',
|
|
means that MariaDB avoids logging blob columns whenever
|
|
possible (eg, blob column was not changed or is not part
|
|
of primary key). 'MINIMAL', means that a PK equivalent
|
|
(PK columns or full row if there is no PK in the table)
|
|
is logged in the before image, and only changed columns
|
|
are logged in the after image
|
|
--binlog-row-metadata=name
|
|
Controls whether metadata is logged using FULL , MINIMAL
|
|
format and NO_LOG. FULL causes all metadata to be logged;
|
|
MINIMAL means that only metadata actually required by
|
|
slave is logged; NO_LOG NO metadata will be logged
|
|
--binlog-space-limit=#
|
|
Alias for max_binlog_total_size. Compatibility with
|
|
Percona server
|
|
--binlog-stmt-cache-size=#
|
|
The size of the statement cache for updates to
|
|
non-transactional engines for the binary log. If you
|
|
often use statements updating a great number of rows, you
|
|
can increase this to get more performance
|
|
--block-encryption-mode=name
|
|
Default block encryption mode for AES_ENCRYPT() and
|
|
AES_DECRYPT() functions. One of: aes-128-ecb, aes-192-ecb,
|
|
aes-256-ecb, aes-128-cbc, aes-192-cbc, aes-256-cbc,
|
|
aes-128-ctr, aes-192-ctr, aes-256-ctr
|
|
--bootstrap Used by MariaDB installation scripts
|
|
--bulk-insert-buffer-size=#
|
|
Size of tree cache used in bulk insert optimization. Note
|
|
that this is a limit per thread
|
|
--character-set-client-handshake
|
|
Don't ignore client side character set value sent during
|
|
handshake
|
|
(Defaults to on; use --skip-character-set-client-handshake to disable.)
|
|
--character-set-collations=name
|
|
Overrides for character set default collations
|
|
--character-set-filesystem=name
|
|
Set the filesystem character set
|
|
-C, --character-set-server=name
|
|
Set the default character set
|
|
--character-sets-dir=name
|
|
Directory where character sets are
|
|
-r, --chroot=name Chroot mariadbd process during startup
|
|
--collation-server=name
|
|
Set the default collation
|
|
--column-compression-threshold=#
|
|
Minimum column data length eligible for compression
|
|
--column-compression-zlib-level=#
|
|
zlib compression level (1 gives best speed, 9 gives best
|
|
compression)
|
|
--column-compression-zlib-strategy=name
|
|
The strategy parameter is used to tune the compression
|
|
algorithm. Use the value DEFAULT_STRATEGY for normal
|
|
data, FILTERED for data produced by a filter (or
|
|
predictor), HUFFMAN_ONLY to force Huffman encoding only
|
|
(no string match), or RLE to limit match distances to one
|
|
(run-length encoding). Filtered data consists mostly of
|
|
small values with a somewhat random distribution. In this
|
|
case, the compression algorithm is tuned to compress them
|
|
better. The effect of FILTERED is to force more Huffman
|
|
coding and less string matching; it is somewhat
|
|
intermediate between DEFAULT_STRATEGY and HUFFMAN_ONLY.
|
|
RLE is designed to be almost as fast as HUFFMAN_ONLY, but
|
|
give better compression for PNG image data. The strategy
|
|
parameter only affects the compression ratio but not the
|
|
correctness of the compressed output even if it is not
|
|
set appropriately. FIXED prevents the use of dynamic
|
|
Huffman codes, allowing for a simpler decoder for special
|
|
applications
|
|
--column-compression-zlib-wrap
|
|
Generate zlib header and trailer and compute adler32
|
|
check value. It can be used with storage engines that
|
|
don't provide data integrity verification to detect data
|
|
corruption
|
|
--completion-type=name
|
|
The transaction completion type. One of: NO_CHAIN, CHAIN,

--deadlock-timeout-short=#
|
|
Short timeout for the two-step deadlock detection (in
|
|
microseconds)
|
|
--default-password-lifetime=#
|
|
This defines the global password expiration policy. 0
|
|
means automatic password expiration is disabled. If the
|
|
value is a positive integer N, the passwords must be
|
|
changed every N days. This behavior can be overridden
|
|
using the password expiration options in ALTER USER
|
|
--default-regex-flags=name
|
|

--default-week-format=#
|
|
The default week format used by WEEK() functions
|
|
--delay-key-write[=name]
|
|
Specifies how MyISAM tables handles CREATE TABLE
|
|
DELAY_KEY_WRITE. If set to ON, the default, any DELAY KEY
|
|
WRITEs are honored. The key buffer is then flushed only
|
|
when the table closes, speeding up writes. MyISAM tables
|
|
should be automatically checked upon startup in this
|
|
case, and --external locking should not be used, as it
|
|
can lead to index corruption. If set to OFF, DELAY KEY
|
|
WRITEs are ignored, while if set to ALL, all new opened
|
|
tables are treated as if created with DELAY KEY WRITEs
|
|
enabled
|
|
--delayed-insert-limit=#
|
|
After inserting delayed_insert_limit rows, the INSERT
|
|
DELAYED handler will check if there are any SELECT
|
|
statements pending. If so, it allows these to execute
|
|
before continuing
|
|
--delayed-insert-timeout=#
|
|
How long a INSERT DELAYED thread should wait for INSERT
|
|
statements before terminating
|
|
--delayed-queue-size=#
|
|
What size queue (in rows) should be allocated for
|
|
handling INSERT DELAYED. If the queue becomes full, any
|
|
client that does INSERT DELAYED will wait until there is
|
|
room in the queue again
|
|
--disconnect-on-expired-password
|
|
This variable controls how the server handles clients
|
|
that are not aware of the sandbox mode. If enabled, the
|
|
server disconnects the client, otherwise the server puts
|
|
the client in a sandbox mode
|
|
--div-precision-increment=#
|
|
Precision of the result of '/' operator will be increased
|
|
on that value
|
|
--encrypt-binlog Encrypt binary logs (including relay logs)
|
|
--encrypt-tmp-disk-tables
|
|
Encrypt temporary on-disk tables (created as part of
|
|
query execution)
|
|
--encrypt-tmp-files Encrypt temporary files (created for filesort, binary log
|
|
cache, etc)
|
|
--enforce-storage-engine=name
|
|
Force the use of a storage engine for new tables
|
|
--eq-range-index-dive-limit=#
|
|
The optimizer will use existing index statistics instead
|
|
of doing index dives for equality ranges if the number of
|
|
equality ranges for the index is larger than or equal to
|
|
this number. If set to 0, index dives are always used
|
|
--event-scheduler[=name]
|
|
Enable the event scheduler. Possible values are ON, OFF,
|
|
and DISABLED (keep the event scheduler completely
|
|
deactivated, it cannot be activated run-time)
|
|
--expensive-subquery-limit=#
|
|
The maximum number of rows a subquery may examine in
|
|
order to be executed during optimization and used for
|
|
constant optimization
|
|
--expire-logs-days=#
|
|
If non-zero, binary logs will be purged after
|
|
expire_logs_days days; It and binlog_expire_logs_seconds
|
|
are linked, such that changes in one are converted into
|
|
the other, presentable as a decimal value with 1/1000000
|
|
of the day precision; possible purges happen at startup
|
|
and at binary log rotation
|
|
--explicit-defaults-for-timestamp
|
|
This option causes CREATE TABLE to create all TIMESTAMP
|
|
columns as NULL with DEFAULT NULL attribute, Without this
|
|
option, TIMESTAMP columns are NOT NULL and have implicit
|
|
DEFAULT clauses
|
|
(Defaults to on; use --skip-explicit-defaults-for-timestamp to disable.)
|
|
--external-locking Use system (external) locking (disabled by default).
|
|
With this option enabled you can run myisamchk to test
|
|
(not repair) tables while the MariaDB server is running.
|
|
Disable with --skip-external-locking
|
|
--extra-max-connections=#
|
|
The number of connections on extra-port

another port
|
|
--flashback Setup the server to use flashback. This enables binary
|
|
log in row mode and will enable extra logging for DDL's
|
|
needed by flashback feature
|
|
--flush Flush MyISAM tables to disk between SQL commands
|
|
--flush-time=# A dedicated thread is created to flush all tables at the

|
List of operators for MATCH ... AGAINST ( ... IN BOOLEAN
|
|
MODE)

FULLTEXT index. Note: FULLTEXT indexes must be rebuilt
|
|
after changing this variable
|
|
--ft-min-word-len=# The minimum length of the word to be included in a
|
|
FULLTEXT index. Note: FULLTEXT indexes must be rebuilt
|
|
after changing this variable

--general-log Log connections and queries to a table or log file.
|
|
Defaults logging to a file 'hostname'.log or a table
|
|
mysql.general_log if --log-output=TABLE is used
|
|
--general-log-file=name
|
|
Log connections and queries to given file
|
|
--getopt-prefix-matching
|
|
Recognize command-line options by their unambiguous
|
|
prefixes
|
|
(Defaults to on; use --skip-getopt-prefix-matching to disable.)
|
|
--group-concat-max-len=#
|
|
The maximum length of the result of function
|
|
GROUP_CONCAT()
|
|
--gtid-cleanup-batch-size=#
|
|
Normally does not need tuning. How many old rows must
|
|
accumulate in the mysql.gtid_slave_pos table before a
|
|
background job will be run to delete them. Can be
|
|
increased to reduce number of commits if using many
|
|
different engines with --gtid_pos_auto_engines, or to
|
|
reduce CPU overhead if using a huge number of different
|
|
gtid_domain_ids. Can be decreased to reduce number of old
|
|
rows in the table
|
|
--gtid-domain-id=# Used with global transaction ID to identify logically
|
|
independent replication streams. When events can
|
|
propagate through multiple parallel paths (for example
|
|
multiple masters), each independent source server must
|
|
use a distinct domain_id. For simple tree-shaped
|
|
replication topologies, it can be left at its default, 0
|
|
--gtid-ignore-duplicates
|
|
When set, different master connections in multi-source
|
|
replication are allowed to receive and process event
|
|
groups with the same GTID (when using GTID mode). Only
|
|
one will be applied, any others will be ignored. Within a
|
|
given replication domain, just the sequence number will
|
|
be used to decide whether a given GTID has been already
|
|
applied; this means it is the responsibility of the user
|
|
to ensure that GTID sequence numbers are strictly
|
|
increasing
|
|
--gtid-pos-auto-engines=name
|
|
List of engines for which to automatically create a
|
|
mysql.gtid_slave_pos_ENGINE table, if a transaction using
|
|
that engine is replicated. This can be used to avoid
|
|
introducing cross-engine transactions, if engines are
|
|
used different from that used by table
|
|
mysql.gtid_slave_pos
|
|
--gtid-strict-mode Enforce strict seq_no ordering of events in the binary
|
|
log. Slave stops with an error if it encounters an event
|
|
that would cause it to generate an out-of-order binlog if
|
|
executed. When ON the same server-id semisync-replicated
|
|
transactions that duplicate existing ones in binlog are
|
|
ignored without error and slave interruption
|
|
-?, --help Display this help and exit
|
|
--histogram-size=# Number of bytes used for a histogram. If set to 0, no
|
|
histograms are created by ANALYZE

|
argument to reset the list accumulated so far
|
|
--in-predicate-conversion-threshold=#
|
|
The minimum number of scalar elements in the value list
|
|
of IN predicate that triggers its conversion to IN

subquery. Set to 0 to disable the conversion
|
|
--init-connect=name Command(s) that are executed for each new connection
|
|
(unless the user has SUPER privilege)
|
|
--init-file=name Read SQL commands from this file at startup

N times speedup. (A conservative setting here would be is
|
|
a high value, like 100 so the short-cutting plan is used

|
conditions to calculate the cardinality of a partial join
|
|
if the last joined table is accessed by full table scan
|
|
or an index scan, 2 - use selectivity of index backed
|
|
range conditions to calculate the cardinality of a

|
partial join in any case, 3 - additionally always use
|
|
selectivity of range conditions that are not backed by
|
|
any index to calculate the cardinality of a partial join,
|
|
4 - use histograms to calculate selectivity of range
|
|
conditions that are not backed by any index to calculate

|
the cardinality of a partial join. 5 - additionally use
|
|
selectivity of certain non-range predicates calculated on
|
|
record samples

cross-database queries such as UPDATE some_db.some_table
|
|
SET foo='bar' while having selected a different or no

Tells the slave thread to not replicate to the specified
|
|
database. To specify more than one database to ignore,
|
|
use the directive multiple times, once for each database.
|
|
This option will not work if you use cross database

sure you have 3.23.28 or later, and use
|
|
replicate-wild-ignore-table=db_name.%.
|
|
--replicate-ignore-table=name
|
|
Tells the slave thread to not replicate to the specified
|
|
table. To specify more than one table to ignore, use the
|
|
directive multiple times, once for each table. This will

work for cross-database updates, in contrast to
|
|
replicate-ignore-db
|
|
--replicate-rewrite-db=name

Updates to a database with a different name than the
|
|
original. Example:
|

|
|
--replicate-same-server-id
|
|
In replication, if set to 1, do not skip events having
|
|
our server id. Default value is 0 (to break infinite
|
|
loops in circular replication). Can't be set to 1 if
|
|
--log-slave-updates is used
|
|
--replicate-wild-do-table=name
|
|
Tells the slave thread to restrict replication to the
|
|
tables that match the specified wildcard pattern. To
|
|
specify more than one table, use the directive multiple
|
|
times, once for each table. This will work for
|
|
cross-database updates. Example:
|
|
replicate-wild-do-table=foo%.bar% will replicate only
|
|
updates to tables in all databases that start with foo
|
|
and whose table names start with bar
|
|
--replicate-wild-ignore-table=name
|
|
Tells the slave thread to not replicate to the tables
|
|
that match the given wildcard pattern. To specify more
|
|
than one table to ignore, use the directive multiple
|
|
times, once for each table. This will work for
|
|
cross-database updates. Example:
|
|
replicate-wild-ignore-table=foo%.bar% will not do updates
|
|
to tables in databases that start with foo and whose
|
|
table names start with bar
|
|
--report-host=name Hostname or IP of the slave to be reported to the master
|
|
during slave registration. Will appear in the output of
|
|
SHOW SLAVE HOSTS. Leave unset if you do not want the
|
|
slave to register itself with the master. Note that it is
|
|
not sufficient for the master to simply read the IP of
|
|
the slave off the socket once the slave connects. Due to
|
|
NAT and other routing issues, that IP may not be valid
|
|
for connecting to the slave from the master or other
|
|
hosts
|
|
--report-password=name
|
|
The account password of the slave to be reported to the
|
|
master during slave registration

tunnel from the master or other clients to the slave. If
|
|
not sure, leave this option unset

|
|
parallel, and handles any conflicts with rollback and
|
|
retry. "conservative" limits parallelism in an effort to
|
|
avoid any conflicts. "aggressive" tries to maximise the
|
|
parallelism, possibly at the cost of increased conflict
|
|
rate. "minimal" only parallelizes the commit steps of
|
|
transactions. "none" disables parallel apply completely
|
|
--slave-parallel-threads=#
|
|
If non-zero, number of threads to spawn to apply in

--slave-run-triggers-for-rbr=name
|
|
Modes for how triggers in row-base replication on slave
|
|
side will be executed. Legal values are NO (default),

|
will not be running on slave. YES and LOGGING means that
|
|
triggers will be running on slave, if there was not
|
|
triggers running on the master for the statement. LOGGING
|
|
also means results of that the executed triggers work
|
|
will be written to the binlog. ENFORCE means that
|
|
triggers will always be run on the slave, even if there
|
|
are triggers on the master. ENFORCE implies LOGGING
