> Key: HUDI-3144
> URL: https://issues.apache.org/jira/browse/HUDI-3144
> Project: Apache Hudi
> Issue Type: Task
> Components: metadata
> Reporter: Manoj Govindassamy
> Assignee: Manoj Govindassamy
> Priority: Blocker
> Fix For: 0.11.0
>
>
> When the metadata index lookups is done for several thousands of keys, the
> keys are looked up in metadata table partitions in a serial fashion key by
> key, leading to the overall delay in the index lookup.
> # When the indexes are laid out in multiple file groups, the lookup can be
> parallelized at the filegroup level
> # Even within a single filegroup, sorted keys can be split and the lookup
> can be done in parallel.
