Stuart Carnie ed344d25f8 feat(storage): Teach storage how to find a distinct set of tag keys ... The TagValues API will perform a linear scan if there is no predicate; otherwise, it will use the index to find a list of candidate series keys. TagKeys expects the predicate to be transformed such that `_measurement` and `_field` are remapped to `\x00` and `\xff` respectively. There is one TODO marked to analyze the predicate for a `\x00 = '<measurement>'` pattern. If found, the predicate can be eliminated and fall back to a linear prefix scan by combining the org, bucket and measurement. This is tracked by issue #13497.		2019-04-24 11:14:22 -07:00
