You can count duplicates in pandas DataFrame by usingDataFrame.pivot_table()function. This function counts the number of duplicate entries in a single column, or multiple columns, and counts duplicates when having NaN values in the DataFrame. In this article, I will explain how to count duplicat...
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...
