Enum Constant Details

PROCESS_MESSAGE_GROUPS_IN_PARALLEL_BATCHES

public static final FifoBatchGroupingStrategy PROCESS_MESSAGE_GROUPS_IN_PARALLEL_BATCHES

Default strategy. Group messages in batches by message group. Each batch contains messages from a single message group. The order of messages within the group is preserved. As message groups are processed in parallel, this strategy provides the maximal throughput.

PROCESS_MULTIPLE_GROUPS_IN_SAME_BATCH

public static final FifoBatchGroupingStrategy PROCESS_MULTIPLE_GROUPS_IN_SAME_BATCH

Each batch contains messages originating from multiple message groups. The order of messages within each group is preserved. Note that FIFO queues do not serve new messages from a group until all the messages for that group in the previous batch have been acknowledged or their visibility expired.
