QuestDB vs Slurm
A side-by-side editorial comparison of QuestDB and Slurm — release velocity, themes, recent moves, and the top alternatives to consider.
QuestDB vs Slurm: at a glance
What is QuestDB?
QuestDB keeps proving its market-data case with reproducible benchmarks between releases.
QuestDB 10.1 and Enterprise 4.1 are the October product releases: merge-append partitions for late data, SUBSAMPLE and exact percentiles, then resource groups, audited views and OIDC for shared clusters. The newest entry is a benchmark rather than a release, replaying 354 million top-of-book events for a full US equities day as Arrow, with memory and throughput figures and rerunnable code. The rest of the feed is technical content on joins, Parquet and QWP compression.
What is Slurm?
Slurm's newest entry is a test case, not a release; 26.05.5 is still current.
Slurm maintains three branches (25.05, 25.11, 26.05). On September 2 it shipped coordinated security releases on all three fixing seven CVEs, including an operator-to-administrator privilege escalation and SQL injection via cluster names. 26.05.5 on October 13 returned to ordinary fixes. The newest feed item is a testsuite commit checking that step cancels in --stepmgr jobs record the job owner rather than root.

QuestDB
5.0DEVOPS
QuestDB keeps proving its market-data case with reproducible benchmarks between releases.
◆ Current state
QuestDB 10.1 and Enterprise 4.1 are the October product releases: merge-append partitions for late data, SUBSAMPLE and exact percentiles, then resource groups, audited views and OIDC for shared clusters. The newest entry is a benchmark rather than a release, replaying 354 million top-of-book events for a full US equities day as Arrow, with memory and throughput figures and rerunnable code. The rest of the feed is technical content on joins, Parquet and QWP compression.
◆ Where it's heading
The release work and the content point the same way: QuestDB as the shared store for trading data, read by many teams and many engines. Enterprise features govern how a cluster is shared, while the posts show the data leaving QuestDB through Parquet and Arrow at volume.
◆ Prediction
Expect the next release to target read-out paths such as Arrow streaming or Parquet export, since the benchmarks are already measuring them; the entries do not show a date.
Slurm
5.0DEVOPS
Slurm's newest entry is a test case, not a release; 26.05.5 is still current.
◆ Current state
Slurm maintains three branches (25.05, 25.11, 26.05). On September 2 it shipped coordinated security releases on all three fixing seven CVEs, including an operator-to-administrator privilege escalation and SQL injection via cluster names. 26.05.5 on October 13 returned to ordinary fixes. The newest feed item is a testsuite commit checking that step cancels in --stepmgr jobs record the job owner rather than root.
◆ Where it's heading
Slurm's cadence is monthly point releases on the 26.05 line with occasional coordinated security drops across all supported branches. The test commit points at accounting accuracy for step-manager jobs as current work.
◆ Prediction
A 26.05.6 point release in November is likely, possibly including the --stepmgr cancel accounting fix the new test covers.
