14.26.3. Description

taler-exchange-aggregator is a command-line tool to run aggregate deposits to the same merchant into larger wire transfers. The actual transfers are then done by taler-exchange-transfer.

The AGGREGATOR_SHARD_SIZE option can be used to allow multiple aggregator processes to run in parallel and share the load. This is only recommended if a single aggregator is insufficient for the workload.

The aggregator uses a special table to lock shards it is working on. If an aggregator process dies (say due to a power failure), these shard locks may prevent the aggregator from resuming normally. In this case, you must run “taler-exchange-dbinit -s” to release the shard locks before restarting the aggregator.
