This is a question. From the docs at http://opentsdb.net/docs/build/html/api_http/uid/tsmeta.html, the ability to create new tsmeta objects via the api was removed in OpenTSDB 2.2.
Now the only way to create metadata objects is to rely on metasync, which needs to scan the whole database. Having this endpoint would have been a convenience. What were the reasons for making this change? Isn't it a breaking change for the API?
