getAsync
@Idempotent
com.google.common.util.concurrent.ListenableFuture<Map<Cell,Value>> getAsync(TableReference tableRef,
Map<Cell,Long> timestampByCell)
Asynchronously gets values from the key-value store when the store allows it. In other cases it just wraps the
result in an immediate future.
- Parameters:
tableRef
- the name of the table to retrieve values from.
timestampByCell
- specifies, for each row, the maximum timestamp (exclusive) at which to retrieve that
row's value.
- Returns:
- listenable future containing map of retrieved values. Values which do not exist (either because they were
deleted or never created in the first place) are simply not returned.
