Apache TsFile vs Simple Analytics: at a glance
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 Simple Analytics?
Privacy analytics tightening its API and moving IP blocking off the CDN
The feed stores each change several times — once with the body text captured as the title, once as a clean headline, sometimes a third time with a date prefix. Behind the duplication, three real changes: API v6 with proper interval support while v5 stays unchanged for compatibility, IP blocking moved off the bunny.net CDN so it works on custom domains and applies per site rather than account-wide, and Events Explorer readability work with column truncation, a full-width toggle and collapsible headers.

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.

Privacy analytics tightening its API and moving IP blocking off the CDN
◆ Current state
The feed stores each change several times — once with the body text captured as the title, once as a clean headline, sometimes a third time with a date prefix. Behind the duplication, three real changes: API v6 with proper interval support while v5 stays unchanged for compatibility, IP blocking moved off the bunny.net CDN so it works on custom domains and applies per site rather than account-wide, and Events Explorer readability work with column truncation, a full-width toggle and collapsible headers.
◆ Where it's heading
The work is about removing borrowed constraints. IP blocking inherited the CDN's limits and blast radius; moving it in-house made it per-site and custom-domain compatible. API v6 does the same for time handling — hourly data separates day and hour, weeks and months carry explicit start dates — while keeping v5 stable so nobody is forced to migrate. Both are the moves of a product whose users integrate it and stay.
◆ Prediction
With v6 shipped alongside an unchanged v5, expect a deprecation timeline for v5 to be the next API announcement, though the entries do not name one.
