Example 1 with Checkpointer

use of org.apache.ignite.internal.processors.cache.persistence.checkpoint.Checkpointer in project ignite by apache.

the class WalDeletionArchiveAbstractTest method testCheckpointStarted_WhenWalHasTooBigSizeWithoutCheckpoint.

/**
 * Checkpoint triggered depends on wal size.
 */
@Test
