Hive Explain Plan Partition Pruning at Jeannette Robert blog

Hive Explain Plan Partition Pruning. Data organization plays a crucial role in query performance. From some of the examples in. You are correct that you should see something like dynamic partitioning event operator in the explain plan. The execution plan is a description of the tasks required for a query, the order in which they'll be executed, and some details about each. The explain plan shows that hive rewrites your query for efficiency to select data from the materialized view that partitions data by. Depending upon whether you follow star schema. Dynamic partition pruning (dpp) is one among them, which is an optimization on star schema queries (data warehouse architecture model). Hive provides an explain command that shows the execution plan for a query. Spark 3.0 has introduced multiple optimization features. The syntax for this statement is as follows: Ensure that queries make use of partition pruning by including the partitioning column in the where clause.
