If a pattern is seen that matches reading the tag keys, it will be
replaced with a direct RPC call to read the tag keys which should be
better optimized than reading from the storage engine tsm1 files.
When a tsi1 partition closes, it waits on the wait group for compactions
and then acquires the lock. Unfortunately, a compaction may start in the
mean time, holding on to some resources. Then, close will attempt to
close those resources while holding the lock. That will block until
the compaction has finished, but it also needs to acquire the lock
in order to finish, leading to deadlock.
One cannot just move the wait group wait into the lock because, once
again, the compaction must acquire the lock before finishing. Compaction
can't finish before acquiring the lock because then it might be operating
on an invalid resource.
This change splits the locks into two: one to protect just against
concurrent Open and Close calls, and one to protect all of the other
state. We then just close the partition, acquire the lock, then free
the resources. Starting a compaction requires acquiring a resource
to the partition itself, so that it can't start one after it has
started closing.
This change also introduces a cancellation channel into a reference
to a resource that is closed when the resource is being closed, allowing
processes that have acquired a reference to clean up quicker if someone
is trying to close the resource.
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.
TagValues 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.
The TimeRangeIterator permits linear or random index scans and
can answer whether the current key has data for the specified time
interval, considering any tombstones.
When there are no tombstones there are some opportunities for
optimization to skip decoding blocks. Specifically, if the
queried time interval overlaps any boundaries of the TSM index entries.
