- actuator 7y agoThis would just kill the performance on virtualized hardware like EBS. You would lose a lot of benefits of Redis at that point.
- manigandham 7y agoYou don't need to fsync on every write, that's what the replica is for. At lower/mid-tier hardware, network is faster than storage and your message is on multiple machines before it's even written to disk so fsync of 1 second is usually fine.
