"-retentionPeriod - retention period in months for the data. Older data is automatically deleted. Default period is 1 month." Not sure I want that in a TSDB!

"-retentionPeriod - retention period in months for the data. Older data is automatically deleted. Default period is 1 month." Not sure I want that in a TSDB! "Reducing disk space usage by deleting unneded time series. This doesn't work as expected, since the deleted time series occupy disk space until the next merge operation, which can never occur." Ouch. But ok, disk space is cheap. The killer point: it seems to be purely json based- no SQL of any kind. I'm not sure about that. A lot of code would have to be changed to fit that model.
