Before Teradata Database writes DBQL data to Data Dictionary tables, it holds the data in cache until either:
- The cache is full.
- You end query logging.
- The number of seconds has elapsed that you define in the DBS Control utility field DBQLFlushRate.You can select a rate from 1 to 3,600 seconds. However, Teradata recommends a flush rate of at least 10 minutes (600 seconds), which is the default. Less than 10 minutes can impact performance.
- You flush the DBQL cache manually.
