How to add caching
Sourcegraph is backed by two Redis caches,
Engineers are welcome to cache data as they see fit.
Troubleshooting local redis access
A simple way to test your caching locally is through the
redis-cli. You can install it using
brew if you do not have it:
brew install redis
You might run into the following error with
sg after installing:
❌ Start Redis failed to write to Redis at 127.0.0.1:6379: MISCONF Redis is configured to save RDB snapshots, but it's currently unable to persist to disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.
Potential solutions for this are:
- Restarting Redis (e.g.
brew services restart redis)
- Changing the config to stop writes:
redis-cli > config set stop-writes-on-bgsave-error no > exit
