NDB Cluster Configuration Files • --ndb-log-empty-epochs=[ON|OFF] • --ndb-log-exclusive-reads=[0|1] Causes updates that produced no changes to be written to the  ndb_apply_status  and ndb_binlog_index  tables, when when  log_slave_updates  is enabled. By default this option is disabled ( OFF ). Disabling  --ndb-log-empty-update  causes updates with no changes not to be written to the binary log. 4167 Command-Line Format --ndb-log-exclusive-reads[={OFF|ON}] System Variable ndb_log_exclusive_reads Scope Global, Session Dynamic Yes SET_VAR  Hint Applies No Type Boolean Command-Line Format --ndb-log-empty-update[={OFF|ON}] System Variable ndb_log_empty_update Scope Global Dynamic Yes SET_VAR  Hint Applies No Type Boolean Default Value OFF • --ndb-log-empty-update=[ON|OFF] Because  --ndb-log-empty-epochs=1  causes the size of the  ndb_binlog_index  table to increase independently of the size of the binary log, users should be prepared to manage the growth of this table, even if they expect the cluster to be idle a large part of the time. By default this option is disabled. Disabling  --ndb-log-empty-epochs  causes epoch transactions with no changes not to be written to the binary log, although a row is still written even for an empty epoch in  ndb_binlog_index . Causes epochs during which there were no changes to be written to the  ndb_apply_status  and ndb_binlog_index  tables, even when  log_slave_updates  is enabled.
