Abstract: By obtaining metadata for transactions submitted by a service to a log-first distributed database of a provider network, a metrics manager may determine database replica performance for those transactions and notify clients of potential performance issues. When an instance of the service submits a write transaction to the log-first distributed database, the transaction may include a host name and a timestamp for the submission of the transaction.

A metrics manager may obtain the transaction timestamps from the replica and calculate a latency metric for the propagation of the transaction from the particular service instance/instance host to the replica. The latency metric may be stored or transmitted to an endpoint (e.g., a client or administrator).
