摘要
One or more client threads are executed. One or more processing threads corresponding to the one or more client threads are executed. The processing threads are configurable to generate statistical information for each database query statement processed by the corresponding client thread. The statistical information is generated from the processing threads. The statistical information is stored in chunks of memory managed via a plurality of queues. The chunks of memory containing the statistics are analyzed. Outlier statements are filtered based on the statistics. Non-outlier statements are stored by a storage device.
