6.4.3 The rpd_exec_stats Table

Note

The Performance Schema table described here is available as of MySQL 8.0.24. HeatWave AutoML queries are shown as of MySQL 8.0.31.

The rpd_exec_stats table stores query execution statistics produced by HeatWave nodes in JSON format. One row of execution statistics is stored for each node that participates in the query. The table stores a maximum of 1000 queries.

For HeatWave AutoML routines that include multiple sub-queries, such as ML_TRAIN, a new record is used for each query.

The rpd_exec_stats table has these columns:

• QUERY_ID

  The query ID. The counter auto-increments for each RAPID or, as of MySQL 8.0.31, HeatWave AutoML query.

• NODE_ID

  The HeatWave node ID.

• EXEC_TEXT

  Query execution statistics. For HeatWave AutoML, this contains the HeatWave AutoML routine that the user runs.
