Apache TsFile vs Kubecost: at a glance
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 Kubecost?
Kubecost cuts three 3.3.2 release candidates in two days, still without notes.
Kubecost opened the 3.3.2 patch line on November 11 and tagged rc.1 through rc.3 by November 13. Each is an automated in-code version bump with no described changes, as with every tag since October, when the 3.3.1 and 3.2.5 candidates went out the same way.

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.
Kubecost
5.0ANALYTICS
Kubecost cuts three 3.3.2 release candidates in two days, still without notes.
◆ Current state
Kubecost opened the 3.3.2 patch line on November 11 and tagged rc.1 through rc.3 by November 13. Each is an automated in-code version bump with no described changes, as with every tag since October, when the 3.3.1 and 3.2.5 candidates went out the same way.
◆ Where it's heading
The quick run of candidates suggests 3.3.2 is close to a final tag. The public tags still say nothing about what the patch fixes.
◆ Prediction
Expect a 3.3.2 final tag within days; what it changes will not be visible from these release notes.
