Array cursors are enabled for storage RPC calls
tsm1:
* Implemented cursors that utilize Array decoders
storage:
* Abstractions to easily switch to Array cursors
* only call ParseTags when necessary
* remove dependency on inmem.Series in tsdb test package
* Measurement and Series are no longer exported. Their use is restricted
to the inmem package
* improve Measurement and Series types by exporting immutable
fields and removing unnecessary APIs and locks
Reduced startup time from 28s to 17s. Overall improvement including
#9162 reduces startup from 46s to 17s for 1MM series across 14 shards.
* did not handle cached values correctly
* sort shards by time in either ascending or descending
order depending on the RPC request ordering to ensure they
are traversed in the correct order.
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.
TODO(sgc): implement `writer` type that handles all the details
of writing frames to the RPC stream. Additional responsibilities
of writer include
* point frame recycling to reduce memory pressure
* skip empty point frames
* skip series frames with no points
When a meta query does not include a time component then it can be
answered exclusively by the index. This should result in a much faster
query execution that if the TSM engine was engaged.
This commit rewrites the following queries such that they make use
of the index where no time component is present:
- SHOW MEASUREMENTS
- SHOW SERIES
- SHOW TAG KEYS
- SHOW FIELD KEYS
* Fprint* functions
* No nakedness
* clarify panic messages
* spacing between case statements
* remove break in favor of return
* remove goto in favor of for { continue }
