Hi all, I have created a PR https://github.com/apache/hudi/pull/13152 for RFC-94 for Hudi Timeline User Interface (UI).
*Problem Statement:* Analysing Hudi Timeline files are quite tedious when debugging, especially when they are encoded in an Avro binary. The only way to navigate or browse the timeline is to use a CLI or a file browser to list out the files under .hoodie. Doing this, we often have a rough time identifying concurrent operations, long running tasks or even jobs that are sometimes stuck. *Solution:* Similar to how Spark-Web-UI renders Event Timeline that displays in chronological order the events related to the executors (added, removed) and the jobs, we can also render Hudi Timeline using a similar approach, and all these will only require a list file operation of the .hoodie directory. This UI can be extended to also show incremental clean range, i.e. which timelines are cleaned and allow users to view instants content by decoding the avro binary to JSON. A simple PoC is implemented in this PR: https://github.com/apache/hudi/pull/13147 As of now, the simple PoC is implemented in plain HTML and vanilla javascript without any CSS libraries, I will leave the decision of the CSS library up to the community. PTAL, any feedback will be appreciated. Cheers, Voon
