What is td-agent?
Fluentd is written in Ruby for flexibility, with performance-sensitive parts in C. However, some users may have difficulty installing and operating a Ruby daemon.
That is why Treasure Data, Inc provides the stable distribution of Fluentd, called td-agent. The differences between Fluentd and td-agent can be found here.
What is calyptia-fluentd?
Our Calyptia also knows that Fluentd is written in Ruby for flexibility, with performance-sensitive parts in C. However, some users may have difficulty installing and operating a Ruby daemon. And td-agent is still seated on Ruby 2.7 due to compatibility reasons and Ruby versioning policy, calyptia-fluentd uses Ruby 3 instead of Ruby 2.7 for now.
That is why Calyptia, Inc. provides the alternative stable distribution of Fluentd, called calyptia-fluentd. The differences between td-agent and calyptia-fluentd are bundled and running Ruby versions for now.
For macOS, td-agent is distributed as .dmg installer.
