D.2.12 Changes in MySQL Cluster-4.1.8 (14 Dec 2004)
---------------------------------------------------
Functionality added or changed:
* Default port for `ndb_mgmd' was changed to 1186 (from 2200) as
this port number was officially assigned to MySQL Cluster by IANA.
* New command in `ndb_mgm', PURGE STALE SESSIONS, as a workaround
for cases where nodes fail to allocate a node id even if it is
free to use.
* New command in `ndb_mgm', CONNECT.
* The ndb executables have been changed to make use of the regular
MySQL command line option parsing features. See
mysql-cluster-command-options, for notes on changes.
* As bonus of the above you can now specify all command line options
in `my.cnf' using the executable names as sections, that is,
`[ndbd]', `[ndb_mgmd]', `[ndb_mgm]', `[ndb_restore]', and so forth.
[ndbd]
ndb-connectstring=myhost.domain.com:1234
[ndb_mgm]
ndb-connectstring=myhost.domain.com:1234
* Added use of section `[mysql_cluster]' in `my.cnf'. All cluster
executables, including mysqld, parse this section. For example,
this is a convenient place to put `ndb-connectstring' so that it
need be specified only once.
* Added cluster log info events on allocation and deallocation of
nodeid's.
* Added cluster log info events on connection refuse as a result of
version mismatch.
* Extended connectstring syntax to allow for leaving the port number
out. For example,
`ndb-connectstring|connect-string=myhost1,myhost2,myhost3' is a
valid connectstring and connect occurs on default port 1186.
* Clear text ndb error messages provided also for error codes that
are mapped to corresponding mysql error codes, by executing `SHOW
WARNINGS' after an error has occurred which relates to the ndb
storage engine.
* Significant performance improvements done for read performance,
especially for blobs.
* Added some variables for performance tuning, `ndb_force_send' and
`ndb_use_exact_count'. Do `show variables like 'ndb%';' in mysql
client for listing. Use `set' command to alter variables.
* Added variables to set some options, `ndb_use_transactions' and
`ndb_autoincrement_prefetch_sz'.
