Change the creation of the rows in HBase from hour to dat

[spico...@gmail.com]

Hello!

By default OpenTSDB creates a new row per time series per hour. It is possible to change this policy, to create a new row by day for example? If yes, how?

I look forward for your answers. Thank you.

 Rgards,

Sure, but it will require a lot of code changes.  Also, if you are storing millisecond-level entries, your rows will be way too large - you probably need to be storing no more than a few values per minute for this to be reasonable.  There will also be some implications on how compactions are performed, meaning the compaction queue will get 24x larger.

John's right that it's a pain but it's something I've been toying with via rollups and some other folks would like to change the row schema to gracefully handle less frequent data. I'll work on generalizing the code and maybe it can come into 2.4.
