This commit improves the startup time when using the `inmem` index by
ensuring that the series are created in the index and series file in
batches of 10000, rather than individually.
Fixes#9486.
This commit adds initial empty sketches back to the tsi1 index, as well
as ensuring that ephemeral sketches in the index `LogFile` are updated
accordingly.
The commit also adds a test that verifies that the merged sketches at
the store level produce the correct results under writes, deletions and
re-opening of the store.
This commit does not provide working sketches for post-compaction on the
tsi1 index.
If all the series in a measurement were tombstone, MeasurementHasSeries
would return true because the ok var was re-used from a prior check
earlier in the func. This caused it to be true all the time unless
the measurment was actually tombstoned.
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.
Now that each shard-local index is maintaining a bitset of series ids,
tracking the series present in the local shard's tsm engine, there is no
need to track shards in the `inmem` index.
This commit removes the methods associated with tracking those
series/shard relationships.
There are two series key formats: the `models` package format, which is
also line-protocol format, and the `tsdb` package format, which is used
by the series file when serialising series keys.
When writing to a series, rather than taking a `models` format key from
the `coordinator` package and then converting it to a `tsdb` package
format, it would be cheaper to keep the key in the `models` format
before hashing it to determine which partition the key lives in.
This commit adds the ability to correctly mark a series as deleted in
the global series file. Whenever a shard engine determines that a series
should be deleted, it checks with each shard's bitset for series that
are to be deleted and are no longer contained in any shard-local
bitsets.
These series are then removed from the series file.
This commit adds a bitset into each shard's in-memory index, to be used to
track undeleted series ids. Currently tsi1 support is not implemented.
When new series are added to the shard, the series id is added
to the bitset. When series are deleted from the shard, the series
ids are removed from the bitset.
Becasue each shard shares the same inmem index reference, the bitset
is stored in the `ShardIndex`, which is local to each shard, and then
different references are passed into the shared `Index` object, depending
on which shard is writing the series.
This commit ensures that the series file should work appropriately on
32-bit architecturs. It does this by reducing the maximum size of a
series file to 512MB on 32-bit systems, which should be fully
addressable.
It further updates tests so that the series file size can be reduced
further when running many tests in parallel on 32-bit architectures.
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.
The DropSeries code path ended up creating a MeasurementSeriesIterator
for each dropped series, this was too expensive just to see if a
series exists.
This adds a HasSeries func and fixes and issue where TSI files were
compacted while an iterator was still in use causing a panic.
The previous sha was taken from a revision on a devel branch that I
thought would continue staying in the tree after it was merged. That
revision was rebased away and the API was changed for the logger.
This updates the usage of the logger and adds a simple package for
constructing the base logger.
The 1.0 version of zap changed the format of the default console logger
so this change moves over to this new logger instead of attempting to
retain backwards compatibility with the old format.
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.
TSI did not check that the max select series limit during planning
the same way that inmem did. This means that the limit could be
set but the planning of a high cardinality query would still OOM
the server. This fixes that limit as well as makes the query interruptible
during planning.
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.
