Class ClientPrepareForDeleteRequest

java.lang.Object

org.apache.ignite.client.handler.requests.table.ClientPrepareForDeleteRequest

public class ClientPrepareForDeleteRequest
extends Object

Client request: for each tuple of a batch, take the locks a delete of that row needs, without writing anything to the storage. The locks are held until the transaction finishes.

Unlike ClientPrepareForUpdateRequest, this one carries no catalog version and no chosen column set: the client does not depend on the index set it sees to build the request. The tuples therefore use the plain key-only layout, in key order, shared with every other key-only thin-client operation.

An explicit read-write transaction is mandatory: a nil transaction or a read-only one is rejected.
