Hi All, Samza Table API is an abstraction for data sources that support random access by key and currently supports operations like Puts, Gets and Deletes on data sources. Partial updates to existing records using the Table API is a commonly requested feature and we have taken a stab to add support for it. Here is the SEP wiki page for it: https://cwiki.apache.org/confluence/display/SAMZA/SEP-30%3A+Support+Partial+Updates+in+Table+API If there are no major blockers, we are tentatively seeking to open a vote on Monday, Dec 13th.
Thanks, Ajo
