Hi, does this version support for the updating and deleting with spark-2.1?
Seems like it does not support, what time is it planned to support it?

release after 3-days of discussion. It will have following features.
1. Introduced new data format called V3(version 3).
Improves the sequential IO by keeping larger size blocklets.So read
larger data at once to memory.
Introduced pages with size of 32000 each for every column inside
blocklet. And min/max is maintained for each page to improve the filter
queries.
Improved compression/decompression of row pages.
Our all performance is improved by 50% compare to old format as per TPC-H
benchmark results.
2. Alter table support in carbondata. (Only for Spark 2.1)
Support renaming of existing table.
Support adding of new column.
Support removing of new column.
Support Upcasting(Ex: from smallint to int) of datatype
