Hi, first time on this forum, sorry if this is a duplicate. I'm running into some weird hardware-specific issues running LogStash that's causing the aggregate plugin to not apply on certain events. However, all of the data piecemeal would be uploaded to Elasticsearch, because I'm grouping events w/ aggregate using a unique ID, and all of the different events (regardless if aggregate ran or not) would contain this unique ID. Is there a feature in Elasticsearch similar to the Logstash aggregate filter, where I can smush different uploaded items together based on if one of their fields is the same value or not?
