Techniques and architectures for non-blocking parallel batching

In an event-based data management system, an event having an associated identifier is received. A mapping operation is performed using the identifier to map the event to a selected one of a plurality of topic partitions. Queues for each of the plurality of topic partitions are managed. The queues for each of the plurality of topic partitions are managed independently of each other. The event is allocated to the selected topic partition based on the mapping operation. The event is placed into the queue for the selected topic partition. A batch of events is sent from the queue for the selected topic partition in response to one or more thresholds being reached.
