MySQL replica that cannot be promoted to master. Conventionally, these are used for background processing jobs, such as taking backups, dumping data to other systems, heavy analytical queries, MapReduce MySQL replicas. The master handles write operations, while replicas handle read-only traffic, batch processing operations, and other tasks. Each MySQL instance within the shard should have the same data, excepting

As with the update stream, VTTablets can subscribe to a VStream to receive events. The VStream can pull events from a VStreamer cross-shard operations. The VTGate servers are capable of scatter-gather operations, but can only stream results. Thus, a query that performs a GROUP BY colx ORDER BY coly may be refused if the intermediate

MySQL replica that cannot be promoted to master.

The master handles write operations, while replicas handle read-only traffic, batch processing operations, and other tasks. Each MySQL instance within the shard should have the same data, excepting value used by the master in a statement is sent in the replication stream, so replicas will have the same value when re-playing the stream. • There is no strict guarantee about ordering: two concurrent statements

extensive fuzzing work; It carried out a fuzzing audit in 2020 which added coverage to complex text processing routines. Vitess is integrated into OSS-Fuzz which allows the fuzzers to run continuously and notify
