Future if rebuilding is in progress or null if not.

rebuildIndexesOnExchange

public boolean rebuildIndexesOnExchange(int cacheId,
                                        AffinityTopologyVersion topVer)

Checks that the indexes need to be rebuilt on the exchange.

Parameters:

cacheId - Cache id.

topVer - Topology version.

Returns:

True if need to rebuild.

cancelRebuildIndexesOnExchange

public void cancelRebuildIndexesOnExchange(Set<Integer> cacheIds,
                                           AffinityTopologyVersion topVer)

Canceling index rebuilding for caches on the exchange.

Parameters:

cacheIds - Cache ids.

topVer - Topology version.

prepareRebuildIndexes

public Set<Integer> prepareRebuildIndexes(Set<Integer> cacheIds,
                                          @Nullable
