A logs data stream is a data stream type that stores log data more efficiently.

In benchmarks, log data stored in a logs data stream used ~2.5 times less disk space than a regular data stream. The exact impact varies by data set.
In benchmarks, log data stored in a logs data stream used ~2.5 times less disk space than a regular data stream, at a small (10-20%) penalty in indexing performance. The exact impact varies by data set and Elasticsearch version.

TODO: add notes.
Starting with version `9.0`, `logsdb` index mode is automatically applied to data streams with names matching pattern `logs-*-*`. This is limited to Elasticsearch instances created in version `9.0` or later, as well as older instances that had no data streams matching pattern `logs-*-*`. In the latter case, `logsdb` index mode can still be configured manually, using the steps described [above](#how-to-use-logsds).
