[Maria-discuss] Known limitation with TokuDB in Read Free Replication & parallel replication ?
by jocelyn fournier 10 Aug '16

10 Aug '16

Hi, After upgrading from TokuDB Enterprise with MariaDB 5.5 to MariaDB 10.1.14, I tried to enable the parallel replication (parallel_mode=optimistic, slave_parallel_threads=4) on a GTID enabled RFR slave, but it leads to random failures. (both master & slave are running 10.1.14) E.g : Could not execute Update_rows_v1 event on table sc_2.sc_param_index; Can't find record in 'sc_param_index', Error_code: 1032; handler error HA_ERR_KEY_NOT_FOUND; the event's master log mysql-bin.008418, end_log_pos 217608066 If I issue a start slave (with sql_slave_skip_counter=0) : Could not execute Update_rows_v1 event on table sc_2.sc_log_cron; Can't find record in 'sc_log_cron', Error_code: 1032; handler error HA_ERR_KEY_NOT_FOUND; the event's master log mysql-bin.008418, end_log_pos 218275984 If I put back slave_parallel_threads to 0, the slave keeps replicating happily without any issue. Is this a known limitation with TokuDB ? Tokudb configuration : tokudb_rpl_lookup_rows=0 tokudb_rpl_unique_checks=0 tokudb_pk_insert_mode=2 tokudb_directio = 1 Thanks and regards, Jocelyn Fournier

[Maria-discuss] New Question: 2 node replication failover/recovery
by AskMonty KB 03 Aug '16

03 Aug '16

Hello, A new question has been asked in "MariaDB Community" by greg_brownell_g. Please answer it at http://mariadb.com/kb/en/2-node-replication-failoverrecovery/ as the person asking the question may not be subscribed to the mailing list. -------------------------------- Is there a way to automate the following: 1. 2 node system set up as master-master replication 2. node 1, master 1 fails. 3. node 2 master 2 is now the active instance. Up to here, all works well. Replication is fast enough. We detect failure and code now uses master 2 on node 2. The problem is sync'ing master 1 when the node 1 restarts, perhaps 5 minutes later. Requirement is: 1. node 2 master 2 continues to run without interruption 2. node 1 master 1 must sync as quickly as possible with node 2 master 2 3. this must be done without human intervention (using scripts, programs, whatever) Thanks. -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/2-node-replication-failoverrecovery/
