Dear Elasticsearch, We use the elasticsearch's \_ttl feature which is not clear to us. The next is written in the latest documentation : ## Expired documents will be automatically deleted regularly. You can dynamically set the indices.ttl.interval to fit your needs. The default value is 60s . The deletion orders are processed by bulk. You can set indices.ttl.bulk\_size to fit your needs. The default value is 10000. Knowing this, we modified the indices.ttl.interval to 30s and indices.ttl.bulk\_size to 3. After, we sent some (2000) logs into our index with \_ttl : 1m . After a while, we noticed that more logs have been deleted as expected. So all logs were deleted within 30s after one minute elapsed but there only 3 logs should have been deleted. Is this normal ? We thought that only 3 logs will be deleted. How is the deletion of logs implemented on the elasticsearch ? Could you give me more information on the deletion of logs ? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
