Katip Elasticsearch

katip-elasticsearch is a scribe for the Katip logging framework that sends structured logs to ElasticSearch.

Features

Built in bounded buffering.
Configurable pool of logging workers to help with high write volume.
Optional field type annotation to avoid mistyping values.
Optional automatic date sharding, so logs can be filed into monthly, weekly, daily, hourly, every minute indices. You can even specify your own index routing logic. This pattern can be seen in the ELK stack as a way of keeping indexes reasonably sized and easy to optimize, rotate, and manage.
Customizable retry policy for temporary outages and errors.
Automatic index and mapping setup.
