Apache SeaTunnel vs Grafana Loki: at a glance
What is Apache SeaTunnel?
SeaTunnel 3.0 ends a six-month gap with 927 PRs and 30 new connectors.
Apache SeaTunnel shipped 3.0.0 on 30 September, its first release since March: 927 merged PRs, 30 new connectors (BigQuery, Salesforce, Google and TikTok Ads, Stripe, Shopify, Mem0, Deep Lake and more), a Python transform, PostgreSQL CDC add-column schema evolution and connectivity dry-runs for S3 and Kafka sources. The prior 2.3.13 release made large files splittable across readers.
What is Grafana Loki?
Loki 4.0 reaches RC3 and narrows S3 storage classes to Standard and Standard-IA.
Loki 4.0 is moving through release candidates. RC1's notes list the breaking changes: the V2 query engine unplugged, Simple Scalable Deployment targets and old /api/prom endpoints removed, protobuf as the default frontend encoding, and several deprecated settings and metrics dropped. RC2 removed every index backend but TSDB, and RC3 adds one more break, limiting S3 storage classes to STANDARD and STANDARD_IA, plus a compactor delete fix.

SeaTunnel 3.0 ends a six-month gap with 927 PRs and 30 new connectors.
◆ Current state
Apache SeaTunnel shipped 3.0.0 on 30 September, its first release since March: 927 merged PRs, 30 new connectors (BigQuery, Salesforce, Google and TikTok Ads, Stripe, Shopify, Mem0, Deep Lake and more), a Python transform, PostgreSQL CDC add-column schema evolution and connectivity dry-runs for S3 and Kafka sources. The prior 2.3.13 release made large files splittable across readers.
◆ Where it's heading
The connector catalogue is moving beyond databases and file stores into SaaS APIs and ad platforms, plus vector and memory stores. Schema evolution in CDC sources keeps widening, one database at a time, and the major version resets expectations after a lengthening release interval.
◆ Prediction
Expect 3.0.x patch releases fixing the new connectors, given how much landed in one version.
Grafana Loki
6.3ANALYTICS
Loki 4.0 reaches RC3 and narrows S3 storage classes to Standard and Standard-IA.
◆ Current state
Loki 4.0 is moving through release candidates. RC1's notes list the breaking changes: the V2 query engine unplugged, Simple Scalable Deployment targets and old /api/prom endpoints removed, protobuf as the default frontend encoding, and several deprecated settings and metrics dropped. RC2 removed every index backend but TSDB, and RC3 adds one more break, limiting S3 storage classes to STANDARD and STANDARD_IA, plus a compactor delete fix.
◆ Where it's heading
Each candidate trims a bit more legacy surface, so 4.0 is a cleanup major that pushes installs onto TSDB and the microservices or single-binary layouts. The Operator had prepared this path since 0.11 and 0.12.
◆ Prediction
Expect a few more RCs with small breaking changes, then 4.0.0 GA and an Operator release that drops the removed schemas.
