Data processing with reliability
Previously defined in the Buffering concept section, the
bufferphase in the pipeline aims to provide a unified and persistent mechanism to store your data, either using the primary in-memory model or using the filesystem based mode.
bufferphase already contains the data in an immutable state, meaning, no other filter can be applied.
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.
