Database segment load balancer

A method performed by a database system, the method comprising:

• initiating a plurality of primary containers to implement a respective database segment instance, wherein each segment of the database is stored on a respective storage volume of a plurality of storage volumes, and wherein each storage volume of the plurality of storage volumes is mounted on a respective primary container of the plurality of primary containers;
• detecting a failure of a first primary container of the plurality of primary containers that is a segment instance of a first database segment;
• and
• in response to the detection, performing a recovery process, including:
• unmounting, from the failed first primary container, a first storage volume storing the first database segment,
• selecting a standby container from a pool of standby containers;
• mounting the first storage volume on the selected standby container, and
• reconfiguring the system so that the system processes queries for the first database segment using the selected standby container instead of the failed first container.

One or more non-transitory computer-readable storage media storing instructions, that when executed by one or more computers of a database system, cause the one or more computers to perform operations comprising:

• initiating a plurality of primary containers to implement a respective database segment instance, wherein each segment of the database is stored on a respective storage volume of a plurality of storage volumes, and wherein each storage volume of the plurality of storage volumes is mounted on a respective primary container of the plurality of primary containers;
• detecting a failure of a first primary container of the plurality of primary containers that is a segment instance of a first database segment;
• and
• in response to the detection, performing a recovery process, including:
• unmounting, from the failed first primary container, a first storage volume storing the first database segment,
• selecting a standby container from a pool of standby containers;
• mounting the first storage volume on the selected standby container, and
• reconfiguring the system so that the system processes queries for the first database segment using the selected standby container instead of the failed first container.
