QuestDB vs Apache Arrow Rust
A side-by-side editorial comparison of QuestDB and Apache Arrow Rust — release velocity, themes, recent moves, and the top alternatives to consider.
QuestDB vs Apache Arrow Rust: at a glance
What is QuestDB?
QuestDB 10.2 adds a power-loss durability mode for WAL tables.
QuestDB 10.1 and Enterprise 4.1 were the October releases: merge-append partitions for late data, SUBSAMPLE and exact percentiles, then resource groups, audited views and OIDC for shared clusters. QuestDB 10.2 follows with a power-loss durability mode for WAL tables, GROUPING SETS, passthrough views with row-level retention and a DEDUP SKIP mode that keeps the first copy of a row. Between releases the feed runs benchmarks and how-tos, most recently live port congestion from free AIS ship data.
What is Apache Arrow Rust?
Arrow Rust cuts release candidates on three older lines at once.
Arrow Rust shipped 60.1.0 on October 28, with Parquet encryption keys redacted from Debug output and read-ahead planning in the push decoder, after 59.3.2 and 58.4.1 fixed a use-after-free in Buffer::shrink_to_fit. On November 13 the 57, 58 and 59 maintenance lines tagged release candidates for 57.3.3, 58.4.2 and 59.3.3 within a minute of each other. The tags carry only version bumps; the changelogs are not in the feed.

QuestDB
5.0DEVOPS
QuestDB 10.2 adds a power-loss durability mode for WAL tables.
◆ Current state
QuestDB 10.1 and Enterprise 4.1 were the October releases: merge-append partitions for late data, SUBSAMPLE and exact percentiles, then resource groups, audited views and OIDC for shared clusters. QuestDB 10.2 follows with a power-loss durability mode for WAL tables, GROUPING SETS, passthrough views with row-level retention and a DEDUP SKIP mode that keeps the first copy of a row. Between releases the feed runs benchmarks and how-tos, most recently live port congestion from free AIS ship data.
◆ Where it's heading
Releases are filling in what a production database needs beyond raw speed: crash safety, broader SQL and data retention controls. The content keeps the market-data focus while reaching into other streams such as ship tracking.
◆ Prediction
Expect another 10.x release within weeks, likely more SQL coverage, while Enterprise picks up the retention and durability features for shared clusters.
Apache Arrow Rust
5.0DEVOPS
Arrow Rust cuts release candidates on three older lines at once.
◆ Current state
Arrow Rust shipped 60.1.0 on October 28, with Parquet encryption keys redacted from Debug output and read-ahead planning in the push decoder, after 59.3.2 and 58.4.1 fixed a use-after-free in Buffer::shrink_to_fit. On November 13 the 57, 58 and 59 maintenance lines tagged release candidates for 57.3.3, 58.4.2 and 59.3.3 within a minute of each other. The tags carry only version bumps; the changelogs are not in the feed.
◆ Where it's heading
The project keeps four major lines alive and patches them together, so downstream users on older Arrow versions still get fixes. Feature work stays on the 60 line.
◆ Prediction
Expect the three patch releases to publish after the vote period, and a 60.2.0 or 61.0.0 candidate to follow.
