Redis Enterprise Software (RS) is fully compatible with open source Redis. Redis Labs contributes extensively to the open source Redis project and employs it inside of RS. As a rule, Redis Labs adheres to the open source’s specifications and makes every effort to update RS with the latest version of Redis.

Redis commands

Any standard Redis client can be used with RS. That said, some of Redis functionality is not applicable in the context of RS, as follows:

  • Shared databases are not supported in RS given their potential negative impact on performance. Redis Labs recommends using dedicated databases instead. Therefore the following commands are blocked and produce an error when executed:
    • MOVE
    • SELECT
  • Because data persistence and backups are managed from RS’s management UI, the following commands are blocked:
    • BGREWRITEAOF
    • BGSAVE
    • LASTSAVE
    • SAVE
  • Because access controls are managed through RS’s managment interface the following commands are blocked
    • ACL DELUSER
    • ACL SETUSER
    • ACL GENPASS
    • ACL LOG
    • ACL SAVE
    • ACL LOAD management UI, the following commands are blocked:
    • BGREWRITEAOF
    • BGSAVE
    • LASTSAVE
    • SAVE
  • Because replication is managed automatically by RS and because it could present a security risk, the following commands are blocked:
    • MIGRATE
    • REPLICAOF
    • SLAVEOF
    • SYNC/PSYNC
  • Commands that are not relevant for a hosted Redis instance are blocked:
    • CONFIG RESETSTAT
    • DEBUG OBJECT/SEGFAULT
    • OBJECT
    • SHUTDOWN
    • CLIENT PAUSE
    • COMMAND INFO
    • COMMAND COUNT
    • COMMAND GETKEYS
    • SCRIPT-DEBUG
    • LATENCY LATEST
    • LATENCY HISTORY
    • LATENCY RESET
    • LATENCY GRAPH
    • LATENCY DOCTOR
  • STRALGO LCS is not yet supported
  • Lastly, only a subset of Redis configuration settings (via CONFIG GET/SET) is applicable to RS. Attempts to get or set a configuration parameter that is not included in the following list produce an error:
    • hash-max-ziplist-entries
    • hash-max-ziplist-value
    • list-max-ziplist-entries
    • list-max-ziplist-value
    • lua-time-limit (value must be between 0 and 60000)
    • notify-keyspace-events
    • set-max-intset-entries
    • slowlog-log-slower-than (value must be larger than 1000)
    • slowlog-max-len (value must be between 128 and 1024)
    • zset-max-ziplist-entries
    • zset-max-ziplist-value

Compatibility with Open Source Redis cluster

RS supports Redis OSS cluster protocol if it is enabled for a database.
