Hi Fabrice, I don't know about the loader, but the data model and query execution don't care if the primary key of a table is multi-column, EXCEPT for the director table. We may reject equi-joins between partitioned tables if the join column is not the director's key column. -Daniel On 12/18/2014 04:21 PM, Fabrice Jammes wrote: > Hello, > > Do you know if I can specify a multi-column primary key in the id > field of a cfg file? > Indeed, for AvgForcedPhotYearly > PRIMARY KEY is (`deepSourceId`,`year`), > > Cheers, > > Fabrice > > ######################################################################## > Use REPLY-ALL to reply to list > > To unsubscribe from the QSERV-L list, click the following link: > https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=QSERV-L&A=1 ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the QSERV-L list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=QSERV-L&A=1
