What is dbt Core?

dbt's 1.x releases now point users at v2 straight from the command line.

dbt 2.0 GA split the project into a proprietary 'dbt' binary and dbt-oss, and the 2.0 dev channel has since added read-only Databricks Unity Catalog access through Lake Compute. The 1.x line is still shipping: 1.13.0b1 adds an opt-in --use-v2-parser that hands parsing to the Fusion parser, and today's 1.12.6 prints a v2 availability notice on dbt --version and relays Fusion parser logs through the otel log format.

What is Fluent Bit?

Fluent Bit ships parallel version lines with eBPF tracing, GCS/OTLP expansion, and a steady stream of crash fixes.

Fluent Bit is running three active release branches simultaneously — 4.2.x, 5.0.x, and 5.1.x — with backports keeping the older lines current on security and correctness fixes. The 5.x line is where new capabilities land: eBPF-based tracing (DNS, scheduler, openssl), expanded GCS output (Workload Identity Federation, Parquet compression, Application Default Credentials), and OTLP metrics improvements. Crash fixes across in_tail, in_winevtlog, out_azure_blob, and the Kafka consumer show active hardening of production edge cases.

dbt Core vs Fluent Bit: editorial side-by-side

dbt Core
ANALYTICS
6.3

dbt's 1.x releases now point users at v2 straight from the command line.

◆ Current state

dbt 2.0 GA split the project into a proprietary 'dbt' binary and dbt-oss, and the 2.0 dev channel has since added read-only Databricks Unity Catalog access through Lake Compute. The 1.x line is still shipping: 1.13.0b1 adds an opt-in --use-v2-parser that hands parsing to the Fusion parser, and today's 1.12.6 prints a v2 availability notice on dbt --version and relays Fusion parser logs through the otel log format.

◆ Where it's heading

The 1.x branch is being turned into an on-ramp for v2: a PyPI banner in 1.12.5, a CLI notice in 1.12.6, deprecated-version warnings and the Fusion parser opt-in in 1.13. Meanwhile 2.0 work concentrates on adapter parity (ClickHouse, Databricks) and Lake Compute.

◆ Prediction

Expect 1.13 to reach GA with the v2 parser opt-in and more migration prompts, and 2.0.x to extend Lake Compute past read-only Unity access. The entries don't show an end-of-life date for 1.x.

Fluent Bit
ANALYTICS
5.0

Fluent Bit ships parallel version lines with eBPF tracing, GCS/OTLP expansion, and a steady stream of crash fixes.

◆ Current state

Fluent Bit is running three active release branches simultaneously — 4.2.x, 5.0.x, and 5.1.x — with backports keeping the older lines current on security and correctness fixes. The 5.x line is where new capabilities land: eBPF-based tracing (DNS, scheduler, openssl), expanded GCS output (Workload Identity Federation, Parquet compression, Application Default Credentials), and OTLP metrics improvements. Crash fixes across in_tail, in_winevtlog, out_azure_blob, and the Kafka consumer show active hardening of production edge cases.

◆ Where it's heading

The eBPF input plugin is building out a full observability surface — DNS, scheduler, openssl traces added over several releases — suggesting a push toward kernel-level telemetry collection as a differentiator from Fluentd and other log shippers. The GCS output expansion (Parquet, WIF, ADC) follows the same pattern: depth-first feature addition to a specific destination rather than broad new connectors. The multiline JSON parser, namespace-scoped systemd capture, and Kubernetes namespace exclusion filter all point toward tighter Kubernetes-native operation.

◆ Prediction

The next move is likely more eBPF trace types (HTTP, TCP) completing the network observability set, and broader OTLP coverage given OpenTelemetry's growing dominance as the wire format in observability stacks.
