Apache TsFile vs Glances
A side-by-side editorial comparison of Apache TsFile and Glances — release velocity, themes, recent moves, and the top alternatives to consider.
Apache TsFile vs Glances: 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 Glances?
After a year of CVE fixes, Glances 4.5.7 turns to making its alerts tell the truth.
Most Glances releases this year carried security patches: 4.5.2 alone corrected eight CVEs, and 4.5.3 to 4.5.6 kept going, ending with a credential leak through URL config values. 4.5.7 in September broke the pattern with a long list of correctness fixes, many of them alerts that fired on the wrong value or never fired, plus WebUI colouring bugs and a fix for --enable-mcp under mcp 2.0. 4.5.8 in October fixed export edge cases.
Apache TsFile vs Glances: editorial side-by-side
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.
Glances
5.0ANALYTICS
After a year of CVE fixes, Glances 4.5.7 turns to making its alerts tell the truth.
◆ Current state
Most Glances releases this year carried security patches: 4.5.2 alone corrected eight CVEs, and 4.5.3 to 4.5.6 kept going, ending with a credential leak through URL config values. 4.5.7 in September broke the pattern with a long list of correctness fixes, many of them alerts that fired on the wrong value or never fired, plus WebUI colouring bugs and a fix for --enable-mcp under mcp 2.0. 4.5.8 in October fixed export edge cases.
◆ Where it's heading
Hardware coverage keeps widening alongside the fixes (Intel, AMD and ARM GPUs, Rockchip NPUs, LXC containers), and a v4 cutover tag in October suggests repository restructuring ahead. The security run appears to have eased since August.
◆ Prediction
Unclear what the v4 cutover changes for users; until it is explained, expect more 4.5.x maintenance releases.
