The regexfilter is an example of a query rewriting filter that uses
regular expressions to match the SQL text and allows a replacement text
to be used for each match of the regular expression.
Regexfilter has no special SQL undertanding, it merely uses the features
avialable inthe regex library to perform matches.
Statements that span multiple packets are not supported by the regex

Added log writing per each status change of each server and repeatedly if server is not running.
Removed SERVER_IS_JOINED checks from rwsplit router.
Maintenance mode prevents a server from having new connections made
to it and stops MaxScale from monitoring a server. It is designed

It prevents new connections and allowsg existing connections to
drain away prior to performaing maintenance on the server.
be extracted from the modules.
This gives a way to verify the API that the module provides as well
as the version of that API. The hope is that this will make it possible
for MaxScale to detect out of date plugins and either adapt to use them
or reject loading them.
Also added the ability to set a release state on a per module basis.
This allows for production ready and non-production ready plugins to
be identified.
command to call the diagnostic entries points of the filters in the
session.
Slight improvements to the two example filters and a fix to the
trim routine.
Only downstream filters are supported currently, i.e. no result
set filtering can be done.
A crude QLA (Query Log All) filter is included as a test harness only
