TokuDB Read Free Replication : Details and Use CasesTim.Callaghan
The biggest innovation in TokuDB v7.5 is Read Free Replication (RFR). I blogged a few days ago posting a benchmark showing how much additional throughput can be achieved on a replication slave, while at the same time lowering the read IO operations to almost zero. The official documentation on the feature is available here.
In this second blog I want to cover the requirements for RFR, as well as some interesting use-cases for the technology.
