Chronix Engine

The storage engine of Chronix — everything between an accepted write and a pruned, decoded read:

• wal — write-ahead log: CRC32c-protected records, group commit, configurable fsync policies, rotation, truncation, crash recovery.
• memtable — lock-free skip-list write buffer with freeze-and-swap flush lifecycle and time-shard routing.
• segment — immutable columnar .csx segment files: row groups, per-column encoding and stats, LZ4/Zstd compression, mmap read path, optional AES-256-GCM field encryption (feature field-encryption).
• storage — pluggable storage backend trait with an atomic local-filesystem implementation and transparent encryption wrapper.
• index — pruning structures: time index, series bloom filters, inverted tag index, skip index, zone maps, and the segment catalog with its manifest WAL + snapshots.
• compaction — hybrid TWCS + size-tiered compaction with streaming K-way merge, tombstone cleanup, and write-amplification budgeting.
• cache — last-value cache, TinyLFU segment cache, metadata cache.
• objstore (feature object-store) — S3/GCS/Azure object storage backend with local disk caching for cold-data tiering.
