Note, updatetable columnstore sucks everywhere, so I don't think so. It's only for OLAP, not OLTP (parse is oltp). What may help @azinman is group-compression

Note, updatetable columnstore sucks everywhere, so I don't think so. It's only for OLAP, not OLTP (parse is oltp). What may help @azinman is group-compression (ex: bigger pages of rows and compress the whole page, where each json-key can be repeated multiple times in a page since each page may have multiple rows). This is what happens on tokudb,hbse,hypertable,cassandra.
