This commit adds a config option to the tsdb Config allowing the size of
the bitset cached in the TSI index to be specified.
Setting the cache size to 0 will disable the cache.
This commit ensures that cached bitset results at the Index level are
updated whenever new series ids are created that would belong in those
bitsets.
For example, if we have a cached bitset for the tuple {mem, region,
west}, and we add the series mem,host=prod,region=west then we would
update the cached bitset for {mem, region, west} with the series id of
the newly written series.
This separates out the dropping of a measurement from the series
to avoid frequent checks to see if a measurement still has series.
The series are dropped individually and we keep track of which
measurements are involved and then delete each measurment afterwards.
This commit firstly ensures that a shard's size on disk is accurately
reported when using the tsi1 index, by including the on-disk size of the
tsi1 index in the calculation.
Secondly, this commit add support for shard streaming/copying when using
the tsi1 index. Prior to this, a tsi1 index would not be correctly
restored when streaming shards.
This commit carries out the initial refactor of the tsi1.Index into
tsi1.Partition. We then create a new tsi1.Index that will be an
abstraction over a collection of Partitions.
This commit adds a basic TSI versioning scheme, by adding a Version field
to an index's MANIFEST file.
Existing TSI indexes will not have this field present in their MANIFEST
files, and thus will be deemed incomatible with the current version.
Users with existing TSI indexes will be able to remove them, and convert the
resulting inmem indexes to the current version of a TSI index using the
influx_inspect tooling.
