Hi, There is something I cannot understand regrading the explain plan of phoenix. I have a table that has 31 regions all together, however the explain plan of the query below suggests that there are 62 parallel scans,
how could it be? Yosi 0: jdbc:phoenix:ec2-54-203-158-70.us-west-2.c> explain select campaign_id, count(*) from fact5 group by campaign_id; +------------+ | PLAN | +------------+ | CLIENT PARALLEL *62-WAY* FULL SCAN OVER FACT5 | | SERVER FILTER BY FIRST KEY ONLY | | SERVER AGGREGATE INTO DISTINCT ROWS BY [CAMPAIGN_ID] | | CLIENT MERGE SO
