> Abstracting Index and Segment interface
> ---------------------------------------
>                 Key: CARBONDATA-284
>                 URL:
>             Project: CarbonData
>          Issue Type: Improvement
>          Components: hadoop-integration
>    Affects Versions: 0.1.0-incubating
>            Reporter: Jacky Li
>             Fix For: 0.3.0-incubating
> This issue is intended to abstract developer API and user API to achieve following goals:
> Goal 1: User can choose the place to store Index data, it can be stored in
> processing framework's memory space (like in spark driver memory) or in
> another service outside of the processing framework (like using a
> independent database service, which can be shared across client)
> Goal 2: Developer can add more index of his choice to CarbonData files.
> Besides B+ tree on multi-dimensional key which current CarbonData supports,
> developers are free to add other indexing technology to make certain
> workload faster. These new indices should be added in a pluggable way.
> This Jira has been discussed in maillist:
