Spark SQL - Skillnad mellan df.repartition och DataFrameWriter

pyspark.sql.functions.substring_index¶ pyspark.sql.functions.substring_index (str, delim, count) [source] ¶ Returns the substring from string str before count occurrences of the delimiter delim. If count is positive, everything the left of the final delimiter (counting from left) is returned. The SQL SUBSTRING function is used to return a part of the string by specified position. For example: SELECT SUBSTRING(‘SUBSTRING Examples’, 1, 9); In certain scenarios, we have columns that store large strings. However, this may be required to get only part of the large string for certain purpose. I am using Spark 1.3.0 and Spark Avro 1.0.0.
