> 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
