Decoupling internal and external tasks in a database environment

A system comprising:

• a multiple tenant cloud-based database platform comprising a plurality of shared storage devices collectively storing database data and an execution platform independent from the plurality of shared storage device;
• and
• one or more processors for managing database tasks, the one or more processors are configured to:
• receive a query directed to database data;
• assign, by a first database query manager, execution of the query to one or more execution nodes of an execution platform,
• determine that execution of the query was unsuccessful;
• reassign, by the first database query manager, the query to a second database query manager to be retried;
• assign, by the second database query manager, a retry of the execution of the query to one or more execution nodes of an execution platform.

A non-transitory computer-readable storage medium, having instructions stored thereon, when executed by one or more processors, cause the one or more processors to:

• receive a query directed to database data;
• assign, by a first database query manager, execution of the query to one or more execution nodes of an execution platform;
• determine that execution of the query was unsuccessful;
• reassign, by the first database query manager, the query to a second database query manager to be retried;
• assign, by the second database query manager, a retry of the execution of the query to one or more execution nodes of an execution platform.
