# 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](https://jira.mariadb.org).
|
|
|
|
## 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](../Routers/Avrorouter.md) documentation.
|
|
|
|
