Overview
A slow query is defined as a query statement in which the query request exceeds a specified time limit. The corresponding statement is referred to as a slow query statement. The slow query feature allows you to directly view detailed command information for Memcached Edition instances in which query requests exceed 10, 20, 40, or 50 milliseconds.
Notes
Slow logs are retained for 15 days.
The default account can query up to 15,000 times per second, while custom accounts are limited to 20 queries per second.
If the process of querying results is slow, try narrowing the time range down for the query.
