The user now requires SELECT privileges on the mysql.roles_mapping
table.
Currently this is a mandatory grant but it needs to be made into an
optional requirement. This allows upgrades from 2.2.9 to 2.2.10 without
needing new grants.
The disk configuration can be different on different servers.
Hence it should be possible to specify the disk space threshold
separately for each server.
Defining the [maxscale] section in a configuration file that is not the
root configuration file is now treated as an error instead of silently
ignored.
The REST API configuration documentation is now located after all other
global parameters in its own section. Added it to the ToC and put a link
to it into the REST API overview document.
Remove the old paragraph and added a note about defining separate
listeners for UNIX domain sockets and network ports.
Also fixed the example listener definition.
The password encryption was documented in the installation instructions
and the main configuration document referred to it as a "section" in the
same document. Having it in the main configuration document makes it the
authoritative source of information.
In some cases you might want to use a specific address/interface
when connecting to a server instead of the default one. With the
global parameter 'local_address' it can now be specified which
address to use.
With this variables set to true, if $VAR is used as a value in the
configuration file, then `$VAR` will be replaced with the value of
the environment variable VAR.
The total timeout for the retrying of interrupted queries can now be
configured with the `query_retry_timeout` parameter. It controls the total
timeout in seconds that the query can take.
The actual connection, read and write timeouts of the connector aren't a
good configuration value to use for abstracted queries as the time that it
takes to execute a query can be composed of both connections, reads and
writes. This is caused by the usage of MYSQL_OPT_RECONNECT that hides the
fact that the connector reconnects to the server when a query is
attempted.
The new `query_retries` parameter controls how many times an interrupted
query is retried. This retrying of interrupted queries will reduce the
rate of false positives that MaxScale monitors detect.
