You can configure redis to limit how much memory is used.

maxmemory 104857600

Of course, that still might not be the result you want.

They do get put into redis.

Maybe we should have a different storage strategy if the data is too big? File storage? I just meant for it to be simple.

If you are going to use redis for storage then you'll need to fine tune it to the processing you are doing (we have).
