Metrics needing one extra byte to fit the output buffer would not be split, so we would emit lines without a line ending. Metrics which overflowed by exactly one field length would be split one field too late, causing truncated fields.
This changes the current use of the InfluxDB client to instead use a
baked-in client that uses the fasthttp library.
This allows for significantly smaller allocations, the re-use of http
body buffers, and the re-use of the actual bytes of the line-protocol
metric representations.
main reasons behind this:
- make adding/removing tags cheap
- make adding/removing fields cheap
- make parsing cheaper
- make parse -> decorate -> write out bytes metric flow much faster
