Examples with SegmentRouter org.apache.ignite.internal.processors.cache.persistence.wal.SegmentRouter used on opensource projects

Example 1 with SegmentRouter

use of org.apache.ignite.internal.processors.cache.persistence.wal.SegmentRouter in project ignite by apache.

the class IgniteDataStorageMetricsSelfTest method checkWalArchiveAndTotalSize.

/**
 * Check the state of wal archive, and whether the total size of
 * wal (and possibly wal archive) match what is expected.
 *
 * @param igniteEx Node.
 * @param hasWalArchive Whether wal archiving is enabled.
 * @throws Exception If failed.
