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 Fulcrum?

Fulcrum turns on Insights, its AI assistant for field data, for every customer.

Fulcrum, a field data collection platform, opened Insights to all customers on all plans as a public beta, on by default. Users ask questions in plain language across up to five apps and get charts, maps and tables, with an org-level off switch. Around it, web, iOS and Android releases fixed map, GPS and photo markup issues and tuned Photo FastFill and Insights styling.

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

Fulcrum turns on Insights, its AI assistant for field data, for every customer.

◆ Current state

Fulcrum, a field data collection platform, opened Insights to all customers on all plans as a public beta, on by default. Users ask questions in plain language across up to five apps and get charts, maps and tables, with an org-level off switch. Around it, web, iOS and Android releases fixed map, GPS and photo markup issues and tuned Photo FastFill and Insights styling.

◆ Where it's heading

Fulcrum is adding AI at both ends of its workflow: FastFill extracts data from photos and audio at capture, and Insights answers questions about the data afterwards. Mobile releases stay focused on reliability for GPS and map features still in beta.

◆ Prediction

Expect Insights to move toward general availability or paid packaging once the beta collects usage, and GPS Integration to leave beta after the current fix cycle.
