MySQL HeatWave User Guide
The rpd_query_stats table stores query
compilation and execution statistics produced by the MySQL HeatWave
plugin in JSON format. One row of data is
stored for each query. The table stores data for the last 1000
executed queries. Data is stored for successfully processed
queries and failed queries.
For MySQL HeatWave AutoML routines that include multiple sub-queries, such
as ML_TRAIN, a new record is used
for each query.
The rpd_query_stats table has these columns:
CONNECTION_ID
The ID of the connection.
QUERY_ID
