Hi Liang, it sounds good.
Any plan to support Apache Beam (instead of Spark directly) ? Regards JB On 08/09/2016 06:02 AM, chenliang613 wrote:
HiI would like to start one discussion thread for Apache CarbonData Roadmap.Your any input and comments would be very appreciated! Apache CarbonData 0.1.0-incubating Support integration with Apache Spark1.5.2,1.6.1,1.6.2Support integration with Apache Hadoop 2.2 later versionColumnar data storeFully Index: it can significantly accelerate query performance and reduces the I/O scans and CPU resources, where there are filters in the query. it can also do skip scan in more finer grain unit (called blocklet) in task side scanning instead of scanning the whole file.Global Multi Dimensional Keys(MDK) based B+Tree Index for all non-measure columnsMin-Max Index for all columns:.Inverted index for all dimensionsOperable encoded data :Through supporting efficient compression and global encoding schemes, can query on compressed/encoded data, the data can be converted just before returning the results to the users, which is "late materialized".Column group: Allow multiple columns to form a column group that would be stored as row format. This reduces the row reconstruction cost at query time.Supports for various use cases with one single Data format : like interactive OLAP-style query, Sequential Access (big scan), Random Access (narrow scan).
