trait BatchAggregatorUS[A, B] extends AnyRef
This batch aggregator exposes a BatchAggregatorUS.run method that allows for batching com.digitalasset.canton.lifecycle.FutureUnlessShutdown computations, defined by a BatchAggregatorUS.ProcessorUS.
Note: it is required that getter and batchGetter do not throw an exception. If they do, the
number of in-flight requests could fail to be decremented which would result in degraded
performance or even prevent calls to the getters.

Abstract Value Members
- abstract def run(item: A)(implicit ec: ExecutionContext, traceContext: TraceContext, callerCloseContext: CloseContext): FutureUnlessShutdown[B]
Runs the processor of this aggregator for the given item, possibly batching several items.
Runs the processor of this aggregator for the given item, possibly batching several items.
- returns
The com.digitalasset.canton.lifecycle.FutureUnlessShutdown completes with the processor's response to this item, after the batch of items has finished. If the processor fails with an exception for some item in a batch, the exception may propagate to the com.digitalasset.canton.lifecycle.FutureUnlessShutdowns of all items in the batch.
