Only ping the batch worker on the first enqueue in a transaction - #272
Conversation
A mutation that writes to the aggregate several times calls `enqueueOperations` once per write, and each call pings. Every ping after the first is redundant: they share a transaction, so they read the same worker record and any wake the first one did is already visible to them. The lookup that packs operations into the transaction's existing row already tells us. Rows written by this transaction still carry an unresolved commitTs, so finding one means an earlier call in this transaction has already pinged. A transaction with ten aggregate writes goes from ten pings to one. Co-Authored-By: Claude Opus 5 (1M context) <[email protected]>

The previous test asserted that a transaction enqueuing more than once still drains, which existing tests already cover, and which holds whether or not the guard is there — removing the guard entirely leaves the whole suite green, since a redundant ping in the same transaction reads the state the first one wrote and no-ops. Count the calls into the component instead, which is the thing that changed. Verified it fails with the guard removed. Co-Authored-By: Claude Opus 5 (1M context) <[email protected]>

keys 1 and 2 as well as key 3, ensuring every enqueued operation is verified
