Changes in 0.2.0

In development, not yet released. tools/release.sh prepare 0.2.0 removes this note.

Collection

The default landing budget, max_delta_bytes, is 4 MiB rather than 8 MiB, so a landed file fits in one message under the default limit of an OpenTelemetry Collector. Measured on a corpus of 6,970 files, 38 exceeded 4 MiB under the old default and none exceeded 8 MiB.
asz repack DEST re-cuts the landed files of a root into a new root under the configured budget, keeping every record’s bytes and order, carrying the cursors over, and building the chains again on the new files. A landed file is never rewritten in place.

asz push sends every landed file and every round to an OpenTelemetry logs receiver over OTLP/HTTP, one log record per line with the line’s bytes unchanged, so a receiver can write the files back byte for byte. Records name the sender with telemetry.sdk.name, the format and its version, the file, the line and its kind. Each file is sent once; push.state records which. The protobuf encoding is written in the project, so the module still has one dependency.

The page reads Session Data and Session Flow and nothing else. It took every record’s time from the index; it now takes it from the record, so a root that arrives with only its landed files and its rounds renders in full, and the index is assembly’s alone.

Session Data’s reader and writer can carry a record as the bytes of its line, unchanged, which is what a repack and a receiver on a wire need so file digests still match.
