I'm trying to figure out where in the code: - the JDBC client sends the query to a drillbit - a drillbit receives the partitioned query - a drillbit sends and receives the data to and from another drillbit
I'm trying to take out the intermediate data between drillbits and write it to a file. Thank you for your help.
