WebJun 24, 2024 · Redgate SQL Monitor is a query optimization tool that features customizable alerts, custom reporting, and a dashboard for monitoring SQL performance. The main features are: A detailed dashboard updating in 15-second intervals, displaying CPU, memory, disk usage, reads and writes, and database wait times. Webquery optimizers in order to enhance query optimization, rather than replacing or discarding traditional query opti-mizers altogether. For example, a common observation about PostgreSQL is that cardinality under-estimates frequently prompt the query optimizer to select loop joins when other methods (merge, hash) would be more e ective [30,31].

Accurate cardinality estimates are fundamental to cost-based optimizers, such as the Db2 optimizer. Cardinality estimation is a process where the optimizer traditionally uses statistics to determine the size of intermediate query results such as the output cardinality of an operator in an access plan that applies one or more predicates.
WebApplying ML-based techniques to optimize traditional databases, or AI4DB, has becoming a hot research spot in recent. Learned techniques for query optimizer(QO) is the forefront in AI4DB. QO provides the most suitable experimental plots for utilizing ML techniques and learned QO has exhibited superiority with enough evidence.
