Mohammad El-Shennawy 637f8c4db7 MDEV-21543: Speed up VARCHAR pad space handling
- Scoped partial optimization for MDEV-21543 improving
PAD SPACE collations for multibyte character sets in
HA_KEYTYPE_VARTEXT1.
- This keeps the old behavior for other cases until
MDEV-38712 is resolved.
- Benchmark: see zulip topic in the PR description
- Results:
- ~3.1% lower wall-clock time
- ~2.1% fewer CPU cycles
- ~0.5% fewer retired instructions
- ~0.7% fewer branch mispredictions

MariaDB: The innovative open source database

MariaDB was designed as a drop-in replacement for MySQL(R) with more features, new storage engines, fewer bugs, and better performance.

MariaDB is brought to you by the MariaDB Foundation and the MariaDB Corporation. Please read the CREDITS file for details about the MariaDB Foundation, and who is developing MariaDB.

MariaDB is developed by many of the original developers of MySQL who now work for the MariaDB Corporation, the MariaDB Foundation and by many people in the community.

MySQL, which is the base of MariaDB, is a product and trademark of Oracle Corporation, Inc. For a list of developers and other contributors, see the Credits appendix. You can also run 'SHOW authors' to get a list of active contributors.

A description of the MariaDB project and a manual can be found at:

Getting the code, building it and testing it

Refer to the following guide: https://mariadb.org/get-involved/getting-started-for-developers/get-code-build-test/ which outlines how to build the source code correctly and run the MariaDB testing framework, as well as which branch to target for your contributions.
