Buffer

Last updated 5 years ago

Was this helpful?

When the data or logs are ready to be routed to some destination, by default they are buffered in memory.

Note that buffered data is not longer a raw text, instead it's in Fluent Bit internal binary representation.

Optionally Fluent Bit offers a buffering mechanism in the file system that acts as a backup system to avoid data loss in case of system failures.
