Query samples have no limits on the number of unique normalized queries tracked, but the sampling is biased towards queries which are slow or frequent. It is possible for a query sample to be selected, but have no associated query metrics. This is the case when the query was slow or frequent for a brief period of time, but was not sustained enough to become a top query.

## Query retention periods

Datadog retains Database Monitoring query data based on the type of data collected:

- Query Metrics are retained for 15 months.
- Query Samples are retained for 15 days.

For more information, see [Data Retention Periods][5].

## Other queries

_Other Queries_ represent the metrics of all queries which do not appear in the top 200. Because a query may be a top query for some time frames but not others, the metrics for a particular query may sometimes be tracked as a distinct normalized query and other times counted in Other Queries.
