-------------------------------------------------------------

- All data displayed on the slow query page comes from the TiDB slow query system table and slow query log. For details, see the slow query log documentation.
- You can filter slow query sentences by time range, database associated with slow query sentences, SQL keywords, SQL types, and the number of slow query sentences displayed. As shown below, the last 100 slow queries within 30 minutes are displayed by default.
Adjust the time before TiDB Server OOM and sort by Max Memory. This way, we can find the SQL list that consumes the amount of memory in the cluster.
