Flushall in redis leads to loading the dataset in memory error

Question

How do I "FLUSHALL" in redis in this situation?

Running redis via docker on PopOs 21.0.4 as shown in the following docker-compose.yml

version: "2.4"
services:
  redis:
    image: redis:5-alpine
    command: redis-server --save "" --appendonly yes
    restart: always
    volumes:
      - "${PWD}//redis/data:/data"
    ports:
      - "6379:6379"

Connecting to redis-cli and issuing a FLUSHALL (or FLUSHDB) command and I get the error:

127.0.0.1:6379[1]> FLUSHALL
(error) LOADING Redis is loading the dataset in memory

Here is docker version:

There is an open issue about that error message. – Shaffer

Answer 1

The error message means that Redis is still loading data, i.e. in your case, the AOF file. You cannot run FLUSHALL until the loading finishes.

If you don't need the data to be loaded, you can delete the AOF file before starting Redis.
