Methods, systems, and media for controlling append-only file rewrites

A system for controlling append-only-file (AOF) rewrites, comprising:

• determine whether the AOF utilization exceeds an AOF utilization threshold;
• prior to an AOF rewrite being performed, determine a recovery time that is an estimate of a time to recover a shard from an AOF when performing the AOF rewrite by at least adding write times for each of a plurality of write operations to the shard;
• determine whether the recovery time exceeds a recovery time threshold;
• and
• when the recovery time is determined to exceed the recovery time threshold, cause the AOF rewrite to be performed.

A non-transitory computer-readable medium containing computer executable instructions that, when executed by a processor, cause the processor to perform a method for controlling append-only-file (AOF) rewrites, the method comprising:

• prior to an AOF rewrite being performed, determining a recovery time that is an estimate of a time to recover a shard from an AOF when performing the AOF rewrite by at least adding write times for each of a plurality of write operations to the shard;
• determining whether the recovery time exceeds a recovery time threshold;
• and
• when the recovery time is determined to exceed the recovery time threshold, causing the AOF rewrite to be performed.
