Change Log
FEATURE: Add timeLagSeries function for computing a time lag
FEATURE: Add timeLagSeriesLists function
FEATURE: Implement filterSeries function
FEATURE: add integralByInterval function
FEATURE: asPercent: rewrite to support different resolution metrics
FEATURE: diffSeries: support different resolution metrics
CHANGE: Supported Go version is 1.16
CHANGE: When checking for block rules, accept absence of file as empty set of rules; no error in that case
CHANGE: carbonapi 404 is not considered an error anymore - carbonapi has separate metric for not-founds for find
CHANGE: Various Default Config changes
CHANGE: Removed x11 parameter to cairo, which is no longer supported.
CHANGE: Changed finds error fan-in logic
- If all backends return and all errors are not found -> return 200 with empty body
- If all backends return errors, and they are mixed -> return 500
CHANGE: Refactored the api to have one backend by design.
CHANGE: Removed back-end filtering for /info, /find, /render requests. Removed dummy merging for all these as well.
CHANGE: New error logic for zipper
CHANGE: Refactored render handler for api. The requests now fail per-target.
CHANGE: Made error merging in zipper more liberal: now at least 3 backend failures are needed along with others all being 404 to result in 500. Before it was 1. - logging improvement Note: this is a temporary solution. The real one is to add replica semantics to zipper backend cluster config
CHANGE: Removed unused graphiteWeb function. Cleaned up limiter that was used only there
CHANGE: Set send_globs to true by default, and mark when otherwise.
CHANGE: Update http handlers for api and zipper to use gorilla/mux
CHANGE: Router: start using middlewares
CHANGE: find: answer with http 422 for requests that are too complex
CHANGE: Changed moving* behavior
BUGFIX: Not found metrics request return HTTP 404

BUGFIX: constantLine: add one more datapoint
BUGFIX: holtWintersAberration: fix index out of range error
BUGFIX: parser: return errors if there are syntax bugs in metric names wrapped by a function
IMPROVEMENT: Added new mode to use memcached.
IMPROVEMENT: Fixed double-counting of requests in case of not-found - not found for find is not considered an error anymore

IMPROVEMENT: traces: add two new options: jaegerBufferMaxCount and jaegerBatchMaxCount
IMPROVEMENT: Terminate goroutine on canceled outbound request
IMPROVEMENT: Reanimated expression parser fuzzer
IMPROVEMENT: Multiple Prometheus metrics improvements.
IMPROVEMENT: Added errors merge and exposure in carbonapi. Now we actually fail when everything fails. Relevant unit tests added
IMPROVEMENT: Added sorting when returning json response in api
IMPROVEMENT: Added context cancellations counter to zipper. It counts cancellations of the main request, not the sub-requests
IMPROVEMENT: Broke /render handler in api into smaller pieces
IMPROVEMENT: Code cleanup, vendor cleanup.
IMPROVEMENT: Removed superfluous use of testify lib. The lib can be pruned from dependencies now

Release v0.1.0
This is the first release of carbonapi from Booking.com. It is the tested version we are running in production. In our setup we use it together with:
Since this is the first release, here are the highlights. Next time it's going to be a changelog.
- improved overall quality, big refactorings, and code cleanups
- fixed request timeouts and cancellation
- better visibility with added metrics and logging
- now it's possible to block requests by a header
