Explicitly state that servers only require `ssl_ca_cert` and that
`ssl_cert` and `ssl_key` are optional in certain cases. Updated the
wording of all parameters and removed obsolete or false documentation.
Enabling it will give a performance improvement and it offloads work from
the CPU. This leads to better and more complete utilization of system
resources.
The server allows both unencrypted and encrypted connections on the same
port. MaxScale only allows either encrypted or unencrypted
connections. The differences as well as the reasoning for this need to be
documented.
The feature was rarely used and was only useful in extremely rare
cases. The functionality can still be emulated, if for some reason needed,
by pointing `logdir` to `/dev/shm` or another tmpfs mount.
- Cannot be supported with std::thread.
- Unlikely that the default size (8MB) would ever be too small and
if it is, there is some problem.
- The stack size can be specified using 'ulimit -s' before starting
MaxScale.
Enabling it with a value of 1 should remove the vast majority of
connection related problems that appear in MaxScale. This should filter
out most of the errors caused by transient network problems.
The configuration guide now links to the runtime configuration in the TOC
instead of the deprecated legacy configuration reloading. The new section
lists the currently supported methods for altering the configuration at
runtime.
Updated links, removed redundant chapters about cluster types and replaced
them with a link to the main tutorial, added maxctrl to the administration section.
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.
Instead of keeping the same information in two places, the build
instructions can simply refer to the actual build script used to prepare
the MaxScale builds. This makes the build process easier.
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.
