🗓️ Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog.

🏷️ 0.0.6 (Unreleased)

🔧 Changed

• Key encoding now uses a single-pass API (TypeEncoder#encode(T, byte[])) across read and write paths, including Bloom filter lookup, WAL encoding, and type writers.
• Added EncodedBytes as the shared return type for encoded payload (bytes + effective length).

⚠️ Breaking

• TypeEncoder no longer exposes bytesLength(T) and toBytes(T, byte[]).
• External/custom TypeEncoder implementations must migrate to:
• EncodedBytes encode(T value, byte[] reusableBuffer)
• Migration intent:
• Use the provided reusable buffer when it is large enough.
• Allocate a larger buffer when needed.
• Return effective encoded length in EncodedBytes.length.

🏷️ 0.0.5

✨ Added

• Data blocks were introduced and the on-disk storage format was significantly improved.
• All disk writes now use a temporary file followed by an atomic rename; all streams are correctly closed.
• Data storage is configurable via the application configuration.
• Data in chunks and data blocks are validated using a magic number and CRC32.
• Added support for Snappy compression.

🏷️ 0.0.4

✨ Added

• Add recovery support to rebuild indexes after failures. (#22)
• Introduce pages for segment-based indexing. (#31)
• Create Directory implementation using java.nio. (#50)
• Add a performance comparison framework for benchmark testing. (#60)
• Add integration tests for deletion and graceful degradation. (#76, #63)
• Add a test class for long-running index operations. (#49)

🔧 Changed

• Improve design of the sorteddatafile package for better modularity. (#59)
• Enhance index configuration validation and parameter consistency. (#81)
• Introduce limits on the number of delta files to prevent unbounded growth. (#75)
