Tornado 4.5 changed request routing in a breaking way. This adds support
for the new behavior while preserving existing behavior for older
versions of Tornado.
- Submit batches serially while the count of buffered measurements exceed a configurable threshold (minimum triggered batch size). Batches can be larger than this value (maximum batch size)
- If the there are measurements in the buffer but the threshold is not met after N seconds (60 by default), submit a batch that is less than minimum triggered batch size.
- rename sprockets_influxdb.set_submission_interval to sprockets_influxdb.set_timeout
- Add new sprockets_influxdb.set_trigger_size
- Move from a single periodic callback object to adding a timeout to the ioloop
- Update tests to work with the new structure
- Add more detailed dubugging information
- Add a flag to disable submission
- Add more environment variables for configuration
- Add a maximum buffer size that discards metrics when there are too many
- Remove correlation-id fields
- Rework how the line protocol is marshalled and support the various data types.
- Remove the accept tag
- Strip down content_type to the ``type/subtype`` format only
- Make ``correlation_id`` a field value and not tag
- Change the precision to second precision, per the InfluxDB docs (use the most
coarse precision for better compression)
