-------------------------------
Assignee: Jian Feng
> enable Hot and cold data separate when ingest data
> --------------------------------------------------
>
> Key: HUDI-2414
> URL: https://issues.apache.org/jira/browse/HUDI-2414
> Project: Apache Hudi
> Issue Type: Improvement
> Components: Writer Core
> Reporter: Jian Feng
> Assignee: Jian Feng
> Priority: Major
>
> when using Hudi to ingest e-commercial company's item data，there are massive
> update data into old partitions，if one record need update， then the whole
> file it belongs need rewrite, that result in every commit nearly rewrite the
> whole table.
> I'm thinking if Hudi can provide a hot and cold data separate tool, work with
> specific column(such as create time and update time) to distinguish hot data
> and cold data, then rebuild table to separate them into different file
> groups, after recreate table， the performance will be much better
