OpenObserve vs Apache SeaTunnel: at a glance
What is OpenObserve?
OpenObserve is running a stabilization train on 0.91 while 0.92 gathers features in RC
Two branches are moving at once. The 0.91 line has taken four patch releases since the start of July, each carrying two or three fixes — memtable rotation, RBAC migration for metric stream names, PagerDuty integration bugs, an anomaly-detection threshold that no longer forces a retrain. In parallel, 0.92 is accumulating in release candidates: agent-level filters, an option to disable default index fields via ZO_FEATURE_DEFAULT_INDEX_FIELDS_ENABLED, and parallel zstd compression. The substantive 0.91.0 release itself — Super Org multi-tenancy, org-level ingestion tokens, and a round of Tantivy search performance work including a footer cache and bloom-filter pruning — sits just outside the recent window.
What is Apache SeaTunnel?
SeaTunnel can finally split one large file across readers — and hasn't shipped since March.
The 2.3.13 release in March is by far the densest in this window: parallel splitting of large files for HDFS, local CSV/text/JSON and logical Parquet splits, CDC source schema evolution on the Flink engine, a checkpoint API with configurable minimum pause, and new connectors for DuckDB, Lance, AWS DSQL and HugeGraph. The releases before it were thinner — 2.3.12 and 2.3.11 are dominated by documentation, much of it Chinese translations of existing connector pages, and 2.3.9 and 2.3.8 are bug fix rollups.

◆ Current state
Two branches are moving at once. The 0.91 line has taken four patch releases since the start of July, each carrying two or three fixes — memtable rotation, RBAC migration for metric stream names, PagerDuty integration bugs, an anomaly-detection threshold that no longer forces a retrain. In parallel, 0.92 is accumulating in release candidates: agent-level filters, an option to disable default index fields via ZO_FEATURE_DEFAULT_INDEX_FIELDS_ENABLED, and parallel zstd compression. The substantive 0.91.0 release itself — Super Org multi-tenancy, org-level ingestion tokens, and a round of Tantivy search performance work including a footer cache and bloom-filter pruning — sits just outside the recent window.
◆ Where it's heading
The shape here is a project consolidating after a large release rather than chasing new surface area. The 0.92 RC contents point at operator control over ingest and index cost — letting users switch off default index fields is a storage-and-write-amplification lever, and parallel compression is the same concern from the CPU side. Agent-level filters suggest the collector-side story is being tightened too.
◆ Prediction
A 0.92.0 general release is the near-term move, carrying the index-field control and compression work, with the 0.91.x patch train tapering once it lands. Whether multi-tenancy from 0.91 gets follow-on quota or billing controls is not yet visible in the RC contents.

SeaTunnel can finally split one large file across readers — and hasn't shipped since March.
◆ Current state
The 2.3.13 release in March is by far the densest in this window: parallel splitting of large files for HDFS, local CSV/text/JSON and logical Parquet splits, CDC source schema evolution on the Flink engine, a checkpoint API with configurable minimum pause, and new connectors for DuckDB, Lance, AWS DSQL and HugeGraph. The releases before it were thinner — 2.3.12 and 2.3.11 are dominated by documentation, much of it Chinese translations of existing connector pages, and 2.3.9 and 2.3.8 are bug fix rollups.
◆ Where it's heading
Two things are happening at once. The engine is getting faster on the shapes that actually stall a pipeline — a single enormous file, a schema that changed under a running CDC job — and the connector catalogue keeps widening toward analytical and vector-adjacent stores rather than more transactional databases. But the cadence has stretched: releases used to land every two to three months, and nothing has shipped in nearly five.
◆ Prediction
Expect the split-and-parallel-read work started for files to extend to more source connectors, since it is the change with the broadest effect on throughput. The release gap is the open question — these entries show a lengthening interval without indicating whether a 2.4 line is being prepared behind it.
