It does this by periodically checking each topic for its size, and if greater than a certain threshold and the topic data has been replicated, deleting segments until the required size is reached. \r\n\r\nThe change also exposes maximum topic and segment sizes via configuration, as I believe some people may want to change these numbers.\r\n\r\nI decided to implement this via a go-routine, so that the function to check the topic sizes could simply walk the filesystem, and not have to worry too much about efficiency vis a vis caching sizes in RAM. I think a design whereby truncation is performed every few minutes is fine (it's how Apache Kafka works), and this approach seems simpler and more robust.\r\n\r\nRemaining:\r\n- letting data nodes know when they must redirect to other nodes for topic data.\r\n\r\n","created_at":"2015-04-14T02:01:25Z","updated_at":"2015-04-15T00:01:44Z","closed_at":"2015-04-15T00:01:44Z","merged_at":"2015-04-15T00:01:44Z","merge_commit_sha":"10e00dce6f647ef41a928fd4947ce68766d5beda","assignee":null,"milestone":null,"commits_url":"https://api.github.com/repos/influxdb/influxdb/pulls/2276/commits","review_comments_url":"https://api.github.com/repos/influxdb/influxdb/pulls/2276/comments","review_comment_url":"https://api.github.com/repos/influxdb/influxdb/pulls/comments{/number}","comments_url":"https://api.github.com/repos/influxdb/influxdb/issues/2276/comments","statuses_url":"https://api.github.com/repos/influxdb/influxdb/statuses/dab100a3b1a31b57a7b0e825d34a5f5f2af3bcf3","head":{"label":"influxdb:broker_truncation","ref":"broker_truncation","sha":"dab100a3b1a31b57a7b0e825d34a5f5f2af3bcf3","user":{"login":"influxdb","id":5713248,"avatar_url":"https://avatars.githubusercontent.com/u/5713248?v=3","gravatar_id":"","url":"https://api.github.com/users/influxdb","html_url":"https://github.com/influxdb","followers_url":"https://api.github.com/users/influxdb/followers","following_url":"https://api.github.com/users/influxdb/following{/other_user}","gists_url":"https://api.github.com/users/influxdb/gists{/gist_id}","starred_url":"https://api.github.com/users/influxdb/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/influxdb/subscriptions","organizations_url":"https://api.github.com/users/influxdb/orgs","repos_url":"https://api.github.com/users/influxdb/repos","events_url":"https://api.github.com/users/influxdb/events{/privacy}","received_events_url":"https://api.github.com/users/influxdb/received_events","type":"Organization","site_admin":false},"repo":{"id":13124802,"name":"influxdb","full_name":"influxdb/influxdb","owner":{"login":"influxdb","id":5713248,"avatar_url":"https://avatars.githubusercontent.com/u/5713248?v=3","gravatar_id":"","url":"https://api.github.com/users/influxdb","html_url":"https://github.com/influxdb","followers_url":"https://api.github.com/users/influxdb/followers","following_url":"https://api.github.com/users/influxdb/following{/other_user}","gists_url":"https://api.github.com/users/influxdb/gists{/gist_id}","starred_url":"https://api.github.com/users/influxdb/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/influxdb/subscriptions","organizations_url":"https://api.github.com/users/influxdb/orgs","repos_url":"https://api.github.com/users/influxdb/repos","events_url":"https://api.github.com/users/influxdb/events{/privacy}","received_events_url":"https://api.github.com/users/influxdb/received_events","type":"Organization","site_admin":false},"private":false,"html_url":"https://github.com/influxdb/influxdb","description":"Scalable
