QuestDB vs sasr
A side-by-side editorial comparison of QuestDB and sasr — release velocity, themes, recent moves, and the top alternatives to consider.
QuestDB vs sasr: at a glance
What is QuestDB?
QuestDB 10.0 collapses ingest and egress into one binary protocol, then aims at agent-run notebooks.
QuestDB's feed mixes release notes, engineering deep dives and customer stories, and the through-line for the past month has been QWP — its own binary columnar wire protocol. It shipped in 10.0, was benchmarked against InfluxDB Line Protocol on ingestion and against ClickHouse and TimescaleDB on Arrow reads, and now has a standalone explainer covering bidirectional dataframe transfer and built-in failover. Between the protocol posts sit JIT compiler internals and production references from banks and exchanges.
What is sasr?
An R package that runs SAS code in a SAS session and hands the results back.
sasr is a bridge from insightsengineering: it opens SAS sessions from R, executes SAS code in them, pulls back logs and results, and moves datasets in both directions. All three visible tags carry byte-identical release notes reading "First CRAN version", so the changelog records the package's scope rather than any per-release delta. There is no visible activity after the May 2023 CRAN landing.

QuestDB
6.3DEVOPS
QuestDB 10.0 collapses ingest and egress into one binary protocol, then aims at agent-run notebooks.
◆ Current state
QuestDB's feed mixes release notes, engineering deep dives and customer stories, and the through-line for the past month has been QWP — its own binary columnar wire protocol. It shipped in 10.0, was benchmarked against InfluxDB Line Protocol on ingestion and against ClickHouse and TimescaleDB on Arrow reads, and now has a standalone explainer covering bidirectional dataframe transfer and built-in failover. Between the protocol posts sit JIT compiler internals and production references from banks and exchanges.
◆ Where it's heading
The protocol work is the thread that matters. QuestDB has been positioning against InfluxDB Line Protocol on ingestion throughput for a while, and 10.0 turned that from a benchmark argument into the default path both in and out of the database. The follow-up posts are consolidation rather than new capability: the same protocol re-explained for a different reader each time, which is what a project does when it needs an ecosystem to adopt a format. Live views and agent-driven notebooks remain the less-proven half of the release.
◆ Prediction
Expect client libraries and third-party connectors to be the next visible work, since a proprietary wire protocol is only worth its switching cost once the dataframe tools speak it. Whether live views leave beta is not something these entries settle.
sasr
0.0DEVOPS
An R package that runs SAS code in a SAS session and hands the results back.
◆ Current state
sasr is a bridge from insightsengineering: it opens SAS sessions from R, executes SAS code in them, pulls back logs and results, and moves datasets in both directions. All three visible tags carry byte-identical release notes reading "First CRAN version", so the changelog records the package's scope rather than any per-release delta. There is no visible activity after the May 2023 CRAN landing.
◆ Where it's heading
The three tags land in nineteen days and say the same thing, which means the arc here is a single push to get an initial version onto CRAN rather than a development sequence. What the notes do establish is a deliberate scope: session lifecycle, code execution, log retrieval and dataset transfer, and nothing beyond that. The package positions itself as plumbing between two runtimes rather than as an attempt to reimplement SAS procedures in R.
◆ Prediction
With identical notes across every tag and no entries since May 2023, the changelog gives no basis for predicting a next move. Any future release would most plausibly track the SAS session interface it wraps.
