Sergey Shelukhin updated HIVE-14535:

Feel free to comment.
Update: we ended up going with sequence number based implementation
Update #2: this feature has been partially merged with ACID; the new table type
is insert_only ACID, and the difference from the regular ACID is that it only
supports inserts on one hand; and that it has no restrictions on file format,
table type (bucketing), and much fewer restrictions on other operations
(export/import, list bucketing, etc.)
Currently some features that used to work when it was separated are not
integrated properly; integration of these features is the remaining work in
this JIRA
