Redis filtering issue with unexpected results and need help on response handling. Any suggestions?
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
