This paper identifies a failure mode in agentic LLM tools like Claude Code, where session compaction summaries misinterpret partial terminal output from timed-out commands as confirmed results, propagating false positives across sessions and model versions without re-verification.
GreptimeDB's Mito2 storage engine uses an LSM-tree design with columnar Parquet SSTs, three-level scan pruning, and TWCS compaction. The blog post provides a full walkthrough of its architecture.
SelfCompact is a scaffolding approach that lets language models autonomously decide when and how to compact long agent traces, achieving better performance with reduced token costs compared to fixed-interval methods.
Snapcompact is a technique that renders text into dense pixel-font images to replace text tokens with cheaper image tokens, achieving near-verbatim recall at a fraction of the input cost.
Lantern introduces a lightweight memory layer that archives conversation turns and retrieves relevant details after compaction, recovering 78.3% of lost facts with zero LLM calls and outperforming MemGPT-based methods.
A user shares a custom Plugin SDK hook that gradually compresses older turns while keeping recent ones raw to prevent context window exhaustion in long OpenClaw sessions, reducing re-sent context by 80%.
