MariaDB MaxScale 2.2.0 Release Notes
Release 2.2.0 is a Beta release.
This document describes the changes in release 2.2.0, when compared to release 2.1.X.
For any problems you encounter, please consider submitting a bug report at Jira.
Changed Features
NamedServerFilter
This filter now uses the PCRE2-libarary to match queries. Previously, it used the POSIX-version of PCRE2. The filter also accepts multiple match-server pairs. Please see the NamedServerFilter documentation for details.
Dropped Features
MaxAdmin
The following deprecated commands have been removed:
enable log [debug|trace|message]disable log [debug|trace|message]enable sessionlog [debug|trace|message]disable sessionlog [debug|trace|message]
The following commands have been deprecated:
enable sessionlog-priority <session-id> [debug|info|notice|warning]disable sessionlog-priority <session-id> [debug|info|notice|warning]
The commands can be issued, but have no effect.
MaxAdmin no longer attempts to interpret additional command line parameters as a
file name to load commands from (e.g. maxadmin mycommands.txt). The shell
indirection operator < should be used to achieve the same effect (maxadmin < mycommands.txt).
New Features
MySQL Monitor Crash Safety
The MySQL monitor keeps a journal of the state of the servers and the currently elected master. This information will be read if MaxScale suffers an uncontrolled shutdown. By doing the journaling of server states, the mysqlmon monitor is able to keep track of stale master and stale slave states across restarts and crashes.
Avrorouter deflate compression
The Avrorouter now supports the deflate compression method. This allows the
stored Avro format files to be compressed on disk. For more information, refer
to the Avrorouter documentation.
