putAsync(Transaction txn, K key, V value)
Maps the specified key to the specified value in this table. Neither the key nor the value can be null.
public CompletableFuture<Boolean> putAsync(Transaction txn, K key, V value)参数
- txn
- Transaction
The transaction id associated with this operation.
- key
- K
key with which the specified value is to be associated
- value
- V
value to be associated with the specified key
返回
CompletableFuture with result true if there was a previous mapping, false otherwise. The future completes exceptionally with IOException for serialization failures, FabricException for fabric related failures.
例外
