## MariaDB MaxScale 2.2
|
|
|
|
* Limited support from Pluggable Authentication Modules (PAM).
|
|
* Proxy protocol support for backend connections.
|
|
* REST-API for obtaining information about and for manipulating the
|
|
resources of MaxScale.
|
|
* MaxCtrl, a new command line client for administering MaxScale
|
|
implemented in terms of the REST-API.
|
|
* Firewall can now prevent the use of functions in conjunction with
|
|
certain columns.
|
|
* Parser of MaxScale extended to support window functions and CTEs.
|
|

|
|
of upcoming 10.3 release.
|
|
* Prepared statements are now parsed and the execution of read only
|
|
ones will be routed to slaves.
|
|
* Server states are persisted, so in case of crash and restart MaxScale
|
|
has the correct server state quicker.
|
|
* Monitor scripts are executed synchronously, so they can safely perform
|
|
actions that change the server states.
|
|
* The Masking filter can now both obfuscate and partially mask columns.
|
|
* Binlog router supports MariaDB 10 GTID at both ends.

|
|
the master. There is also limited capability for rejoining nodes.
