In total there is roughly 3 TB of data (we are well aware that such data layout is not ideal) Requirement: Run a query against this data to find a small set of records, maybe around 100 rows matching some criteria Code: import sys from pyspark import SparkContext from pyspark.sql...
Query pushdown:The connector supports query pushdown, which allows some parts of the query to be executed directly in Solr, reducing data transfer between Spark and Solr and improving overall performance. Schema inference: The connector can automatically infer the schema of the Solr collec...
