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.

**-c** *FILENAME* \| **--config=**\ ‌\ *FILENAME*
   Use the configuration and other resources for the exchange to operate
   from *FILENAME*.

**-h** \| **--help**
   Print short help on options.

**-L** *LOGLEVEL* \| **--loglevel=**\ ‌\ *LOGLEVEL*
   Specifies the log level to use. Accepted values are: ``DEBUG``, ``INFO``,
   ``WARNING``, ``ERROR``.

**-l** *FILENAME* \| **--logfile=**\ ‌\ *FILENAME*
   Send logging output to *FILENAME*.

**-T** *USEC* \| **--timetravel=**\ \ *USEC*
   Modify the system time by *USEC* microseconds.
   *USEC* may be prefixed with ``+`` or ``-`` (e.g. ``-T +300``).
   This option is intended for debugging/testing only.

**-t** \| **--test**
   Run in test mode and exit when idle.

**-v** \| **--version**
   Print version information.

**-y** \| **--kyc-off**
   Run without KYC checks. Talk with your regulator before using this option.
