Looking for some pointers on where the partitioning is figured out in the source when a query is executed. I'm investigating an alternative partitioning scheme based on date patterns (using external tables).
The situation is that I have data being written to some HDFS root directory with some dated pattern (i.e. YYYY/MM/DD). Today I have to run an alter table to insert this partition every day. It gets worse if you have hourly partitions. This seems like it can be described once (root + date partition pattern in the metastore). So looking for some pointers on where in the code this is currently handled. Thanks, Steve
