Introduction to the Redis 6 release
|
|
|
|
|
===================================
|
|
|
|
|
|
|
|
|
|
Redis 6 improves Redis in a number of key areas and is one of the largest
|
|
|
|
|
Redis releases in the history of the project, so here we'll list only
|
|
|
|
|
the biggest features in this release:
|
|
|
|
|
|
|
|
|
|
* The modules system now has a number of new APIs that allow module authors
|
|
|
|
|
to make things otherwise not possible in the past. It is possible to
|
|
|
|
|
store arbitrary module private data in RDB files, to hook on different
|
|
|
|
|
server events, capture and rewrite commands executions, block clients on
|
|
|
|
|
keys, and so forth.
|
|
|
|
|
* The Redis active expire cycle was rewritten for much faster eviction of keys
|
|
|
|
|
that are already expired. Now the effort is tunable.
|
|
|
|
|
* Redis now supports SSL on all channels.
|
|
|
|
|
* ACL support, you can define users that can run only certain commands and/or
|
|
|
|
|
can only access only certain keys patterns.
|
|
|
|
|
* Redis now supports a new protocol called RESP3, which returns more
|
|
|
|
|
semantical replies: new clients using this protocol can understand just
|
|
|
|
|
from the reply what type to return to the calling program.
|
|
|
|
|
* There is server-side support for client-side caching of key values. This
|
|
|
|
|
feature is still experimental and will get more changes during the next
|
|
|
|
|
release candidates, but you can already test it and read about it here:
|
|
|
|
|
https://redis.io/topics/client-side-caching
|
|
|
|
|
* Redis can now optionally use threads to handle I/O, allowing to serve
|
|
|
|
|
2 times as much operations per second in a single instance when
|
|
|
|
|
pipelining cannot be used.
|
|
|
|
|
* Diskless replication is now supported even on replicas: a replica is now
|
|
|
|
|
able, under certain conditions the user can configure, to load the RDB
|
|
|
|
|
in the first synchronization directly from the socket to the memory.
|
|
|
|
|
* Redis-benchmark now supports a Redis Cluster mode.
|
|
|
|
|
* SRANDMEMBER and similar commands have a better distribution.
|
|
|
|
|
* Redis-cli improvements.
|
|
|
|
|
* Systemd support rewritten.
|
|
|
|
|
* A Redis Cluster proxy was released here:
|
|
|
|
|
https://github.com/artix75/redis-cluster-proxy
|
|
|
|
|
* A Disque module for Redis was released here:

|

|
|

|
|
|
|
|
|
Thanks to all the users and developers who made this release possible.
|
|
|
|
|
We'll follow up with more RC releases, until the code looks production ready
|
|
|
|
|
and we don't get reports of serious issues for a while.
|
|
|

|
|

|
|
|
|
|
