What is dqcheckr?

dqcheckr adds drift analysis, then removes the YAML a user had to hand-write.

dqcheckr runs configurable data-quality checks over files and DuckDB tables, driven by YAML dataset configs and recording results as snapshots. The 0.2.0 release added the ability to compare two historical snapshots and report per-column statistical drift, schema changes and trend charts, extending the tool from point-in-time checking into change over time. The most recent tag, 0.3.0, attacks the other friction point by generating the config itself from a sniff pass over the data.

What is Semgrep?

Semgrep keeps spending releases on parser breadth and large-repo throughput, not new surface.

Ten consecutive releases have gone into the engine rather than the product. The recurring shape is a parser refresh (Solidity, Ruby, Dart), a scan-performance change, and a batch of correctness fixes for Pro analysis. Nothing in this window changes what a team buys Semgrep for; it changes how reliably a scan finishes on a large repository.

dqcheckr adds drift analysis, then removes the YAML a user had to hand-write.

◆ Current state

dqcheckr runs configurable data-quality checks over files and DuckDB tables, driven by YAML dataset configs and recording results as snapshots. The 0.2.0 release added the ability to compare two historical snapshots and report per-column statistical drift, schema changes and trend charts, extending the tool from point-in-time checking into change over time. The most recent tag, 0.3.0, attacks the other friction point by generating the config itself from a sniff pass over the data.

◆ Where it's heading

Both moves point the same way: reduce what the operator has to write and know. Config generation removes the hand-authored YAML that gated first use, list_runs() and validate_config() make an existing setup inspectable, and the snapshot comparison turns accumulated run history into a second product surface. Check coverage keeps widening underneath — outlier detection, composite keys, row-count and file-size ceilings — and the reporting layer moved from rmarkdown to Quarto, with existing 0.1.x databases auto-migrated on first run.

◆ Prediction

Expect the generated configs and the drift reports to converge, so a sniffed config can seed thresholds from the snapshot history rather than from defaults, plus continued growth in the numbered QC check catalogue.

5.0

Semgrep keeps spending releases on parser breadth and large-repo throughput, not new surface.

◆ Current state

Ten consecutive releases have gone into the engine rather than the product. The recurring shape is a parser refresh (Solidity, Ruby, Dart), a scan-performance change, and a batch of correctness fixes for Pro analysis. Nothing in this window changes what a team buys Semgrep for; it changes how reliably a scan finishes on a large repository.

◆ Where it's heading

The performance work is converging on one problem: very large monorepos. File targeting now batches path filtering across worker domains, rule parsing shards by bytes instead of worker count, and a new Pro memory policy lets a scan trade RAM for skipping on-disk caching. Running alongside it is a quieter thread of trust work, and the 1.173.0 fix for silently dropped targets belongs to it: a file whose path filtering failed appeared in neither the findings nor the skipped list, which is the kind of gap that undermines a scan report more than any missing rule.

◆ Prediction

Expect the parser-refresh-plus-throughput cadence to continue, with the memory policy and the dependency-path output likely graduating out of experimental once large-repo users report back on them.
