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.
Fixes#8819.
Previously, the process of dropping expired shards according to the
retention policy duration, was managed by two independent goroutines in
the retention policy service. This behaviour was introduced in #2776,
at a time when there were both data and meta nodes in the OSS codebase.
The idea was that only the leader meta node would run the meta data
deletions in the first goroutine, and all other nodes would run the
local deletions in the second goroutine.
InfluxDB no longer operates in that way and so we ended up with two
independent goroutines that were carrying out an action that was really
dependent on each other.
If the second goroutine runs before the first then it may not see the
meta data changes indicating shards should be deleted and it won't
delete any shards locally. Shortly after this the first goroutine will
run and remove the meta data for the shard groups.
This results in a situation where it looks like the shards have gone,
but in fact they remain on disk (and importantly, their series within
the index) until the next time the second goroutine runs. By default
that's 30 minutes.
In the case where the shards to be removed would have removed the last
occurences of some series, then it's possible that if the database was already at its
maximum series limit (or tag limit for that matter), no further new series
can be inserted.
They rebased a revision we were previously relying upon that allowed us
to use the vanity name so we are reverting back to an older version with
the old import path.
It looks like the real import path to the project is go.uber.org/zap
instead of github.com/uber-go/zap since the example in the project
references that path.
The logging library has been switched to use uber-go/zap. While the
logging has been changed to use structured logging, this commit does not
change any of the logging statements to take advantage of the new
structured log or new log levels. Those changes will come in future
commits.
This has various benefits:
- Users embedding InfluxDB within other Go programs can specify a different logger / prefix easily.
- More consistent with code used elsewhere in InfluxDB (e.g. services, other `run.Server.*` fields, etc).
- This is also more efficient, because it means `executeQuery` no longer allocates a single `*log.Logger` each time it is called.
* Capitalize first letter of message
* Log all services staring consistently
* Remove some extraneous log statements in meta.Store
* Log data dirs for meta, data and hinted handoff
