Alexander Lapin updated IGNITE-17260:
-------------------------------------
Description:
It's required to explicitly register an intent of starting readOnly
transaction, so following decorator producer is expected in IgniteTransactions
{code:java}
/**
* Decorated {@code IgniteTransactions} instance that will start read-only
transactions.
*
* @return Decorated {@code IgniteTransactions} instance that will start
read-only transactions.
*/
IgniteTransactions readOnly(); {code}
Besides that Transaction interface should be extended with
{code:java}
boolean isReadOnly();{code}
and
{code:java}
HybridTimestamp readTimestamp();{code}
methods.
And finally three more overloaded methods will be added to the InternalTable
{code:java}
CompletableFuture<BinaryRow> get(
BinaryRowEx keyRow,
@NotNull HybridTimestamp readTimestamp,
@NotNull ClusterNode recipientNode
);
CompletableFuture<Collection<BinaryRow>> getAll(
Collection<BinaryRowEx> keyRows,
@NotNull HybridTimestamp readTimestamp,
@NotNull ClusterNode recipientNode
);
Publisher<BinaryRow> scan(
int p,
@NotNull HybridTimestamp readTimestamp,
@NotNull ClusterNode recipientNode
);
{code}
Please, pay attention, that new parameter @NotNull ClusterNode recipientNode
is added.
