For time-series data, the columnar layout means queries only need to read the columns involved, and the compression ratio is usually significantly higher than text CSV, so I/O cost is lower in scenarios where large files are scanned repeatedly.

UnverifiedColumnar storage can deliver performance improvements of tens of times over traditional row-based databases for aggregation operations, because queries only read the involved columns rather than entire rows.69% similarUnverifiedA sequential full table scan (Seq Scan) on large tables means substantial I/O, which in a managed database directly translates into higher compute and storage I/O costs.67% similarUnverifiedEmbedding-based retrieval converts files or code blocks into vectors and stores them in an index, taking the most similar blocks at query time, which can turn stuffing the whole repo in into taking a small block by relevance, compressing the cost of a single call to a constant level.67% similarVerifiedReranking uses a cross-encoder to score query-document pairs one by one, with accuracy far higher than vector similarity but at higher computational cost, so fine ranking is done only on the small number of candidates after coarse ranking, forming a two-stage architecture of coarse ranking plus fine ranking.67% similarUnverifiedAdding metadata (document ID, section path, effective date) to chunks improves retrieval quality more than adding another reranker.66% similar
