What is Apache TsFile?

TsFile is quietly rebuilding itself as an Arrow-speaking interchange format

Apache TsFile is the columnar time-series file format underlying IoTDB, maintained as three parallel implementations in Java, C++ and Python. Recent releases have concentrated on the C++ and Python ends: SIMD paths and parallel reads in 2.4.0, an Arrow-compatible result path from C++ through to Python DataFrames in 2.3.0, and conversion scripts from CSV, Parquet and Arrow into TsFile in 2.3.1. The Java side gets steadier, smaller work — serialized-size calculation, schema modification during writes, encryption configuration.

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.

TsFile is quietly rebuilding itself as an Arrow-speaking interchange format

◆ Current state

Apache TsFile is the columnar time-series file format underlying IoTDB, maintained as three parallel implementations in Java, C++ and Python. Recent releases have concentrated on the C++ and Python ends: SIMD paths and parallel reads in 2.4.0, an Arrow-compatible result path from C++ through to Python DataFrames in 2.3.0, and conversion scripts from CSV, Parquet and Arrow into TsFile in 2.3.1. The Java side gets steadier, smaller work — serialized-size calculation, schema modification during writes, encryption configuration.

◆ Where it's heading

The centre of gravity has moved from format features to ecosystem reach. Arrow-backed DataFrames and format converters are not about storing time series better; they are about making TsFile readable by the Python analytics stack without a translation layer, which is the gap that keeps a specialized format confined to its own database. The C++ performance work in 2.4.0 serves the same end, since the Python bindings sit on top of it. Version numbering runs on two lines at once, with 1.1.x backports still shipping alongside the 2.x series.

◆ Prediction

Given the direction of the Arrow work, the Python interface is the most likely target for further capability rather than the Java one. The notes do not indicate when the 1.1 maintenance line ends.

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.
