v5.1.0 / 2021.06.17

• [FEATURE] Flush last metrics on Statsd#close #180 by @kbogtob
• [ENHANCEMENT] Do not try to flush where there is no available message_queue [#189][] by @remeh
• [OTHER] Add pry to development dependencies and enable gem in Gemfile #192 by @ivoanjo

Known issues

If the DogStatsD client is instantiated before a fork, the forked process won't copy the companion thread that the original client needs to flush and the client won't work properly. This issue will be addressed in an upcoming version. If you are concerned by this issue, please read this section of the README.

v5.0.1 / 2021.04.09

• [OTHER] Re-introduce a Statsd#batch method to help with compatibility with v4.x versions. #176 by @remeh
  • It is deprecated and will be removed in v6.x
  • It does not have the exact same behavior as the batch method from v4.x versions since the flush could now automatically occur while the batch block is executed if the buffer has been filled.
• [BUGFIX] Safely close concurrent resources on Sender #175 by @marcotc

v5.0.0 / 2021.04.07

API breaking changes

1. This new major version uses automatic buffering with preemptive flushing, there is no need to manually batch the metrics together anymore. The preemptive flushing part means that just before the buffer gets full, a flush is triggered. Manual flush is still possible with the Statsd#flush method. The Statsd#batch method has been removed from the API. What would have been written this way with the v4 API:

require 'datadog/statsd'

statsd = Datadog::Statsd.new('127.0.0.1', 8125)

statsd.batch do |s|
  s.increment('example_metric.increment', tags: ['environment:dev'])
  s.gauge('example_metric.gauge', 123, tags: ['environment:dev'])
end

should be written this way with the v5 API:

require 'datadog/statsd'

statsd = Datadog::Statsd.new('127.0.0.1', 8125)

statsd.increment('example_metric.increment', tags: ['environment:dev'])
statsd.gauge('example_metric.gauge', 123, tags: ['environment:dev'])

# synchronous flush
statsd.flush(sync: true)

2. Statsd#initialize parameter max_buffer_bytes has been renamed to buffer_max_payload_size for consistency with the new automatic batch strategy. Please note the addition of buffer_max_pool_size to limit the maximum amount of messages to buffer.
