The much-awaited Redis version 4.0 is here! Here at Redis we make an ongoing effort to ensure that our customers can enjoy all the latest and greatest features of Redis.

We are excited to announce that our latest version of Redis Enterprise, our core engine that powers Redise Cloud and Redise Pack products, now supports the latest release of Redis – version 4.0.

What’s new in Redis version 4.0

Redis 4.0 release adds several significant enhancements including:

  • Redis Modules – the most talked about ability to extend Redis functionality by directly hooking into Redis core and extending it
  • Async non blocking delete operations – new ‘UNLINK’ command is same as ‘DEL’ but working in a non-blocking way. To get the same with ‘FLUSHDB’ and ‘FLUSHALL’ use the new ‘ASYNC’ flag
  • Improvements to existing eviction policies and a brand new eviction policy – LFU (Least Frequently Used)
  • Mixed RDB-AOF format – this comes enabled by default in Redise. This allows faster rewrites and reloads when using the AOF persistence.
  • Active defrag – this feature was contributed by our very own Oran Agra. Redis now actively defrag its allocated memory, freeing up unused ‘holes’ in RAM.
  • Many more improvements about performance,memory usage and bug fixes

You can learn more about the release in this blog post and if you really want the full blown list you can always visit the release notes.
