It’s possible to add % wildcards in the ‘source’ option of
namedserverfilter.
Allowed values, for an IP address only are:
X.%.%.%
X.Y.%.%
X.Y.Z.%
The match any ‘%’ is not allowed
When processing the response to a COM_QUERY, the rows will be
terminated by an EOF packet. However, as the type byte of an
EOF packet is 0xFE and the identifying byte of an 8 byte length
encoded integer is also 0xFE it is not possible to distinguish
the two except by also looking at packet length.
The masking filter will assume payloads less than 2^24 - 1. The
behaviour if payloads larger than than are encountered can be
configured.
The actual implementation follows in a subsequent change.
Now that the query classifier can be given COM_STMT_PREPARE packets
in addition to COM_QUERY packets, binary prepared statements will
be subject to the same analyses as any other statement.
The slave nodes par od the cluster are sorted by wsrep_local_index or
server priority.
The sorted list od nodes is then used in ‘wsrep_sst_donor’ variable.
Note: candidate master servers are always at the end of the list
Galeramon queries all slave nodes for SHOW VARIABLES LIKE
'wsrep_node_name'
The server list, currently not sorted, is used in SET GLOBAL
wsrep_sst_donor = “list”. The statement is sent to all slave nodes
MXS-391. The user hosts in the SQL backends can now contain wildcard
addresses (e.g.basicuser@%.com or someuser@myhost_.org). Authenticating
these types of users is rather heavy since it requires looking
up the client host name.
All modules now declare a name for the module. This is name is added as a
prefix to all messages logged by a module. The prefix should help
determine which part of the system logs a message.
The external config.h header defined functions and structures that are
intended to be used by modules. The internal header contains functions
that are used only by the MaxScale core.
The header is divided into two parts, an external and an internal one. The
actual splitting is done in a later commit and this commit only prepares
the header for the split.
The filter converts bulk inserts inside transactions into LOAD DATA LOCAL
INFILE statements. This allows multiple INSERT statements to be streamed
in a more efficient manner.
The module should be in the experimental package as it is still at an
experimental stage.
