Example 2 with GroupState

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

the class CheckpointHistory method earliestCheckpointsMapSnapshot.

/**
 * Creates a snapshot of {@link #earliestCp} map.
 * Guarded by checkpoint read lock.
 *
 * @return Snapshot of a map.
 */
public EarliestCheckpointMapSnapshot earliestCheckpointsMapSnapshot() {
    Map<UUID, Map<Integer, GroupStateSnapshot>> data = new HashMap<>();

Example 3 with GroupState

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

the class CheckpointHistory method initialize.

/**
 * @param checkpoints Checkpoints.
 * @param snapshot Earliest checkpoint map snapshot.
 */
public void initialize(List<CheckpointEntry> checkpoints, EarliestCheckpointMapSnapshot snapshot) {
    for (CheckpointEntry e : checkpoints) histMap.put(e.timestamp(), e);

            Map<Integer, GroupState> groupStateMap = snapshot.groupState(checkpointId);
            // states map was not persisted (that means this checkpoint wasn't a part of earliestCp map)
            if (snapshot.checkpointWasPresent(checkpointId) && groupStateMap == null)
                continue;
            if (groupStateMap != null)
                entry.fillStore(groupStateMap);

        } catch (IgniteCheckedException e) {
            U.warn(log, "Failed to process checkpoint, happened at " + U.format(timestamp) + '.', e);
