Redis Streams adapter may cause event drops?

[RomainFranceschini]

Hi, I use the Redis stream adapter but I'm concerned with event dropping.

AFAIU, since this adapter evicts old entries when adding new events, a greater insertion rate than the read rate would cause event drops.

I guess this is acceptable since the maxLen configuration can be tweaked, but I'm struggling to find a good way to monitor the stream in production and gather valuable data that would help me have a comfortable maxLen value.

Am I overthinking this?
