Creating a Periodic Checkpoint
The creation of periodic checkpoints and the number of checkpoints to retain is specified when you configure your data grid.
Before you beginBefore creating a checkpoint, ensure that the following prerequisites are met:
- Ensure that a quorum of state keepers is running.
The following data grid configuration options apply to periodic checkpoints:
checkpoint_interval
Use to specify the time interval (in seconds) for creating checkpoints. The default is 0, which means periodic checkpoints are not created.
checkpoint_retention_limit
Use to specify the number of checkpoints to retain. Older checkpoints are automatically removed as long as no active queries use the checkpoint.
- Procedure
- To enable the creation of a periodic checkpoint, use the
grid create command as is shown in the following example:
grid create copyset_size=2 statekeeper_count=3 checkpoint_interval=600 checkpoint_retention_limit=5 mygrid
