predisHow can I optimize the memory usage of Redis when using PHP?

1. Use Redis::setOption() to enable the Redis::OPT_SCAN option. This will allow you to iterate over keys without loading the entire dataset into memory.

2. Use Redis::pipeline() to execute multiple commands in a single transaction. This will reduce the number of requests and therefore the amount of memory used.

3. Use Redis::expire() to set a time-to-live (TTL) for keys. This will ensure that keys expire when they are no longer needed, freeing up memory.

4. Use Redis::memoryUsage() to get the memory usage of a given key. This will allow you to identify which keys are using the most memory and take appropriate action.

5. Use Redis::memoryOptimize() to optimize the memory usage of a given key. This will reduce the memory usage of a key without changing its value.

6. Use Redis::getOption() to get the current configuration options. This will allow you to identify any options that are not set optimally for your use case.

7. Use Redis::config() to set configuration options. This will allow you to configure Redis to use the optimal settings for your use case.

Example code

$redis = new Redis();
$redis->setOption(Redis::OPT_SCAN, true);

Output example

None
