When this was taking place, there are periods when Redis throughput dropped.
We're running Redis on an EC2 instance (on an EBS device). Every time Redis tries to re-write the AOF file it ends up slowing down to an almost complete halt.
AOF background rewrite monitoring. AOF files will grow forever, but thankfully Redis comes with functionality to consolidate an AOF file into a minimal set of commands needed to reconstitute the dataset. Redis does this in a background rewrite process to avoid holding up the master process.Redis aof re write as a logarithmic equation
