Manticore Search: Fast, efficient, drop-in replacement for Elasticsearch

Manticore also provides a programmatic HTTP JSON protocol for more versatile data and schema management, with Elasticsearch-compatible writes support. Built in C++, Manticore Search starts quickly and uses minimal RAM (around 40MB RSS for an empty instance), with low-level optimizations contributing to its impressive performance. Note that upon exiting the MySQL client, the Manticore container will be stopped and removed, resulting in no saved data, so use this way only for testing / sandboxing purposes.
