Restrictions

To prevent a single user from occupying resources for queries for a long time, note the following restrictions:

If the execution duration of a query statement exceeds15 seconds, a timeout error will be returned.
If a query generates a large amount of data and an error is returned, you need to simplify the query statement.
Only the first 4,000 records are returned for a single query.
A single query statement can be used to perform a maximum of two join queries for tables.
A maximum of 200 advanced queries can be created for each account.

To get full functionality of advanced queries, you need to enable the resource recorder. The following describes how the resource recorder may affect your use of advanced queries.

If you have never enabled the resource recorder, no resources can be queried with an advanced query.
If you have enabled the resource recorder and a monitoring scope is specified, only resources within the monitoring scope can be queried with an advanced query.
If you enable the resource recorder and disable it after a period of time, only resource data collected during the period when the resource recorder is enabled can be queried with an advanced query.

For details about how to enable and configure the resource recorder, see Configuring the Resource Recorder.
