redis_copy

Rapidly copies all keys from one Redis instance to another. Uses SCAN to read keys and pipelines DUMP/RESTORE to move values.

Dependencies

$ go get gopkg.in/redis.v5

Running

Edit the file to set the Redis connection info, and maybe tune the number of records per chunk (currently 7500) and number of goroutines (10), then:

$ go run redis_copy.go
