[Q] keys scan command about keydb

[JohnSully]

Sorry we couldn’t help you. I’ll update this issue if we are able to improve Keys in the future.

While KeyDB is Multithreaded the Keys command will hold a lock for the duration of its execution. This has the same issues as with Redis.

We are looking into allowing lock free execution of commands and I will add this to the list of things to look at.

In short yes - it has the same issue but for a different reason.

Thanks.

The KEYS command now only blocks the current database (and thread) in unstable (slated for v5.1.0). It will still block on accesses to the same DB the KEYS command is running on, but we're a lot closer now to a fully non blocking KEYS.
