What is Apache TsFile?
TsFile 2.5 adds Go to its Java, C++ and Python implementations.
Apache TsFile is the columnar time-series file format underneath IoTDB. The 2.x line has concentrated on the native and Python ends: Arrow-compatible results into Python DataFrames in 2.3.0, CSV, Parquet and Arrow conversion scripts in 2.3.1, SIMD and parallel reads in 2.4.0, and in October 2.5.0 with table-model read and write APIs for Go plus persistent dataset indexes. The old 1.1 line still gets occasional backport releases, most recently 1.1.4 in September.
What is Deepnote?
Deepnote's agent now runs from first prompt to finished notebook without handoffs.
Deepnote's most recent entry, in October, makes Deepnote Agent a single agent that keeps context from the first instruction to the finished notebook, and lets private and shared projects sit in the same folder. It builds on June's native Codex connection to a workspace's notebooks, schedules and data, and July's MCP tools that let agents create and attach integrations. Spring releases added run snapshots, Git sync, Polars support, PDF export and AI usage metering.

Apache TsFile
2.5ANALYTICS
TsFile 2.5 adds Go to its Java, C++ and Python implementations.
◆ Current state
Apache TsFile is the columnar time-series file format underneath IoTDB. The 2.x line has concentrated on the native and Python ends: Arrow-compatible results into Python DataFrames in 2.3.0, CSV, Parquet and Arrow conversion scripts in 2.3.1, SIMD and parallel reads in 2.4.0, and in October 2.5.0 with table-model read and write APIs for Go plus persistent dataset indexes. The old 1.1 line still gets occasional backport releases, most recently 1.1.4 in September.
◆ Where it's heading
TsFile is being shaped into an interchange format that non-JVM tools can read and write directly, with each release widening language coverage or speeding up the native path. The 1.1 backports show IoTDB users on older versions are still being supported.
◆ Prediction
Expect a 2.5.x patch release fixing the new Go and index features, following the pattern of 2.3.1 after 2.3.0.
Deepnote
2.5ANALYTICS
Deepnote's agent now runs from first prompt to finished notebook without handoffs.
◆ Current state
Deepnote's most recent entry, in October, makes Deepnote Agent a single agent that keeps context from the first instruction to the finished notebook, and lets private and shared projects sit in the same folder. It builds on June's native Codex connection to a workspace's notebooks, schedules and data, and July's MCP tools that let agents create and attach integrations. Spring releases added run snapshots, Git sync, Polars support, PDF export and AI usage metering.
◆ Where it's heading
The notebook is being repositioned as a workspace agents operate in, both Deepnote's own agent and external ones like Codex. Releases have slowed from monthly in spring to one entry each in July and October.
◆ Prediction
Further agent capabilities or more external agent connections are the likeliest next move; the slower cadence makes timing hard to read.
