We see the checkpoint group Z_TEST with the two subkeys set in the coding (logpoint1, subkey1). The entry below logpoint1 is created due to the protocol setting of the LOG-POINT ID statement. The entry below subkey1 is created, because the first ASSERT ID statement in the demo prog...
For more information about checkpoints, see Database checkpoints (SQL Server).The following diagrams show a transaction log before and after truncation. The first diagram shows a transaction log that has never been truncated. Currently, four virtual log files are i...

In the example above, we can see that thecurrent_lsn, thecheckpoint_lsnand theflushed_to_disk_lsnhave the same value. They are all in the last active log (id10844). In fact there are no transaction for the moment. The snake is at its minimal size (Innodb_redo_log_logical_size) : ...
Techniques for replicating data between database systems without taking checkpoints are provided. In an embodiment, a capture process restarts. Upon restarting, the capture process reestablishes an association with an apply process. A particular logical time maintained by the apply process is then com...

Reclaiming space in redo log Recall that recovery always starts at the last written checkpoint lsn. Thereforelog.last_checkpoint_lsndefines the beginning of the log files. Data at lsns smaller than that can be freed (unless there are some Log Consumers attached, such as Clone Archiver which mig...
Messages related to checkpoint operations performed by the WiredTiger storage engine. To specify the log level for WTCHKPT components, use the systemLog.component.storage.wt.wtCheckpoint.verbosity setting. WTCMPCT New in version 5.3.

in the SELECT statement, you must also configure the CheckPoint Column Name parameter. Important For example, set the CheckPoint Column Name parameter to id, the Initial Value of CheckPoint Column parameter to 0, and the SELECT Statement parameter to SELECT * FROM xxx WHERE ID > ?. Each ...
