To change the maximum size of a string type in Redis, you need to modify the value of the redis-server configuration parameter called maxmemory. This parameter specifies the maximum amount of memory that Redis can use for all its data structures.
By default, the maxmemory parameter is set to zero which means that Redis will use as much memory as it needs until the system runs out of memory. To change the maximum size of a string type, you need to set the maxmemory parameter to a specific value that limits the total amount of memory that Redis can use.
To do this, follow these steps:
- Open the Redis configuration file located at
/etc/redis/redis.conf(may differ based on your installation method). - Find the line that starts with
maxmemory. - Replace the default value of
0with the desired maximum memory size in bytes. - Save and close the configuration file.
- Restart the Redis server using the command
sudo systemctl restart redis.
For example, if you want to limit the maximum size of a string type to 100MB, you can set the maxmemory parameter to 100000000.
