Hi All,got a question in regards to Redis.We encounter issues, that filtering isn't working as expected. We use Redis as a whitelist, meaning that we extract a field from the raw log and using the EXISTS command to check if the key (build as a combination of strings) exists in Redis. If it does not exists in Redis the return value is `'0'` and we will drop the event.What we discovered is, that events that should be dropped are available at the destination.My questions are:What is / Is there a return value from Redis in case Redis was not able to process the query (EXISTS command)? Proabably not `'0'` , but if there is a response I somehow need to catch it.That was the only thing that came to my mind could cause the issue.Do you have some other ideas?Cheers,Mario
Redis filtering issue with unexpected results and need help on response handling. Any suggestions?
Can you share your exact filter in the Drop function? Are you comparing with `0` or `'0'`?
are you sure it's coming back as a string?
i'd validate the type of var
can you share the pipeline?
See screenshot.What you can't see is the RegExtract function.Already changed the drop filter to a more conservative one. Before it was as described:`__asset_exist == '0' && __asset_exist_lower == '0'`
Also this route is running for over a month with ~120m events per day, but there are only a few (<20) suspicious events.That is why I was asking this:""" What is / Is there a return value from Redis in case Redis was not able to process the query (EXISTS command)?
