Redis Why is fetching long?

Question

Redis

There is a server with a radish, 250-400k records and all the responses to the selection by key are long from 10 to 30 seconds .. keys like word_123_user_3
Maybe we are doing something wrong or is there some other solution to quickly write and read information in parallel?

Answer 1

Are you doing keys word_123_*?

Use SCAN

Answer 2

There is also a Tarantula (trantool).

But I would still start differently - with profiling.
Whether at you badly fulfills search.
Either you are trying to upload a million already selected records from the server to the client.
Either the key does not match what you are looking for.
You need to profile.
