Module kumo.jsonl

{{since('dev')}}

This module provides utilities for reading and writing JSONL (newline-delimited JSON) log files stored in zstd-compressed segments, as produced by kumomta's logging subsystem.

It supports:

• Writing — kumo.jsonl.new_writer produces a LogWriter that compresses records into time-based segment files.

• Reading (single consumer) — kumo.jsonl.new_tailer returns a streaming tailer for a single consumer with optional filtering, checkpointing, and configurable batching.

• Reading (multiple consumers) — kumo.jsonl.new_multi_tailer fans a single read pass out to multiple independent consumers, each with its own filter, batch parameters, and checkpoint.
