Generally CacheStore is synchronously updated with every cache operation,
unless you configure CacheConfiguration.setWriteBehind(true). If
write-behind is enabled, then Ignite will batch store operations and
execute them asynchronously in bulks.

CacheStore will be called for the data stored locally on an individual
node. It will contain only the data for that node.
