fluent-plugin-buffer-event_limited

This gem is a mutation of the fluent-plugin-buffer-lightening buffer plugin by tagomoris.

Fluentd buffer plugin on memory to flush with many types of chunk limit methods:

• events count limit in chunk

These options are to decrease latency from emit to write, and to control chunk sizes and flush sizes.

Installation

Do gem install fluent-plugin-buffer-event_limited or fluent-gem ....

Configuration

EventLimited buffer plugin can be enabled with all of buffered output plugins.

To flush chunks per 100 records, configure like this:

<match data.**>
  type any_buffered_output_plugin
  buffer_type event_limited
  buffer_chunk_records_limit 100
  # other options...
</match>

Options of buffer_type file are also available:

<match data.**>
  type any_buffered_output_plugin
  buffer_type event_limited
  buffer_chunk_limit 10M
  buffer_chunk_records_limit 100
  # other options...
</match>

For less delay

For more frequently flushing, use flush_interval and try_flush_interval with floating point values on Fluentd v0.10.42 or later:

<match data.**>
  type any_buffered_output_plugin
  buffer_type event_limited
  buffer_chunk_records_limit 100
  # other options...
  flush_interval 0.5
  try_flush_interval 0.1 # 0.6sec delay for worst case
</match>
