DragonFly
➢ Replication from Redis is available
➢ Replication process is the same as with redis
➢ HA is supported via Sentinel or HAproxy
➢ You can continue to use the redis-cli
➢ You don’t need to change or upgrade SW libraries
Migrating to it
Generally, there are 3 ways to migrate
from Redis to DragonflyDB
I. Dump the Rredis DB and restore to DragonflyDB
II. Setup DragonflyDB as a slave then promote it to master
III. Same as II, but with Sentinel or HAproxy in front
