Apache Iceberg vs Glances
A side-by-side editorial comparison of Apache Iceberg and Glances — release velocity, themes, recent moves, and the top alternatives to consider.
Apache Iceberg vs Glances: at a glance
What is Apache Iceberg?
Iceberg 1.12 drops Spark 3.4 and starts laying groundwork for the v4 table spec.
Apache Iceberg maintains several minor lines at once, and most visible work is backports and dependency updates. 1.12.0 on September 30 is broader: it removes Spark 3.4 support, adds V4 groundwork such as relative paths in the spec and Parquet or Avro manifests, adds a REST unregister-table endpoint and content stats in the spec, and writes shredded Variant from Flink. Kafka Connect now reports commit failures instead of swallowing them.
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 Iceberg
0.0ANALYTICS
Iceberg 1.12 drops Spark 3.4 and starts laying groundwork for the v4 table spec.
◆ Current state
Apache Iceberg maintains several minor lines at once, and most visible work is backports and dependency updates. 1.12.0 on September 30 is broader: it removes Spark 3.4 support, adds V4 groundwork such as relative paths in the spec and Parquet or Avro manifests, adds a REST unregister-table endpoint and content stats in the spec, and writes shredded Variant from Flink. Kafka Connect now reports commit failures instead of swallowing them.
◆ Where it's heading
The project is moving from maintenance-only releases back to spec work, with V4 pieces landing in stages. Older engine versions are being dropped as that happens.
◆ Prediction
Expect more V4 spec and core pieces in 1.13 and patch releases on 1.11 and 1.12; a V4 release date is not visible in the entries.
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.
