Hi Xuchuanyin,
Thanks for asking the doubt.
Consider the following example where we have 2 segments:
Seg_0 : R1(0-100), R2(100-200), R3(200-300)
Seg_1 : R4(0-50), R5(150-250), R6(250-350)
Now the new ranges formed after merging all the overlapping ranges for both
the segments will be:
R1(0-100
Hi ManishNalla:
"""
merging the overlapping intervals and getting new intervals(ranges) out of
them
"""
===
What do you mean by saying this? Can you give an example for it.

emm, eliminating delta files to enhance query performance is quite reasonable
and compaction is a candidate for it. However I have some questions about
this, maybe they will help in your design.
Q1:
A segment with delta files means there are some UD(update/delete) operations
on this segment before
1. Will dataloading to MV be supported for all the table properties and load
options provided by Carbon. ?
2. Will the newly proposed "alter datamap datamapname compact" command
support all compaction types(auto/major/minor/custom) ?
3. Would load to partition table having MV also be supported ?
