@unnumberedsubsec Description
|
|
@c man begin DESCRIPTION
|
|
Set or get the maximum size, in bytes, of any given log file.
|
|
|
|
When logging is configured, the default maximum log size is 100MiB.
|
|
|
|
It is possible that a log file will be larger than @var{lg_max}: The
|
|
logs comprise log entries, and TokuDB always writes a complete log
|
|
entry into a log file. Thus if a log entry is larger than
|
|
@var{lg_max}, then the resulting log file could be larger.
|
|
|
|
You may call @code{DB_ENV->set_log_max} at any time on any environment
|
|
that has been created but hasn't yet been closed. Subsequently
|
|
written log files will be smaller than the specified size.
