Enum Constant Details

SINGLE_WRITE_EVENT

public static final NoSQLSubscriptionConfig.StreamDeliveryMode SINGLE_WRITE_EVENT

When a table is subscribed and configured with this delivery mode, every single write to the subscribed table will be delivered in a stream event StreamOperation.PutEvent or StreamOperation.DeleteEvent. This is the default delivery mode and does not require users to explicitly set it.

GROUP_ALL_IN_TRANSACTION

public static final NoSQLSubscriptionConfig.StreamDeliveryMode GROUP_ALL_IN_TRANSACTION

When a table is subscribed and configured with this delivery mode, all writes events to the table and its child tables if any, including single key writes, will be grouped in their respective transactions of the write events. All writes in a transaction will be delivered as a single stream event StreamOperation.TransactionEvent. For a single key write, the group size will be 1.

The table configured with this delivery mode must be a subscribed table in the subscription, and must be a top table, otherwise the subscription would fail with SubscriptionFailureException.
