I use Logstash file input plugin to read those log files, and there are several compressed logs already there. Each day a couple hundred thousand files are sent to different buckets, then processed by logstash. Each document in an Elasticsearch index must have a unique _id, and Filebeat uses this property to avoid ingesting duplicate events. This input does not support this, it can lead to duplicates as you cannot guarantee that multiple Logstash instances will not try to read the same object in S3 at the same type.

The current sincedb implementation of this plugin only relies on the object key and doesn't use the file offset at all, so when we stop logstash in a middle of reading a file we don't have the choice to read the file back at the beginning causing duplicates in the log stream. Everything works fine until it gets to the last file, which it creates entries in Elasticsearch for endlessly. The upstream output must have a TCP route to the port (defaults to 9800) on an interface that this plugin is bound to.
