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 OpenNLP?

Apache OpenNLP ships 3.0.0 final, closing a milestone track that ran since spring.

Apache OpenNLP runs three release lines: 1.9.x for Lucene and Solr 8 users, 2.5.x as the stable line, and the 3.0 track that went through six milestones. On 12 November the project tagged 3.0.0 final alongside a 2.5.13 patch, again shipping both lines on the same day. The tags carry no release notes in the feed, so what changed since 3.0.0-M6 is not visible here.

Q
QuestDB
DEVOPS
5.0

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.

A5.0

Apache OpenNLP ships 3.0.0 final, closing a milestone track that ran since spring.

◆ Current state

Apache OpenNLP runs three release lines: 1.9.x for Lucene and Solr 8 users, 2.5.x as the stable line, and the 3.0 track that went through six milestones. On 12 November the project tagged 3.0.0 final alongside a 2.5.13 patch, again shipping both lines on the same day. The tags carry no release notes in the feed, so what changed since 3.0.0-M6 is not visible here.

◆ Where it's heading

The 3.0 milestones combined security hardening (deserialization and XXE fixes, model-loading allowlists) with new text tooling such as the Unicode normalization engine and a SymSpell spell checker, while 2.5.x added RoBERTa inference through ONNX Runtime. With 3.0.0 out, the 2.5 line is likely to move to backports only, and new work should land on 3.x.

◆ Prediction

Expect a 3.0.1 patch and continued 2.5.x security backports; whether 1.9.x gets further releases is unclear from these entries.
