Retrieves or sets the auto broadcast join threshold

Source: R/spark_context_config.R
spark_auto_broadcast_join_threshold.Rd

Configures the maximum size in bytes for a table that will be broadcast to all worker nodes when performing a join. By setting this value to -1 broadcasting can be disabled. Note that currently statistics are only supported for Hive Metastore tables where the command `ANALYZE TABLE <tableName> COMPUTE STATISTICS noscan` has been run, and file-based data source tables where the statistics are computed directly on the files of data.

Usage

spark_auto_broadcast_join_threshold(sc, threshold = NULL)

Arguments

sc

A spark_connection.

threshold

Maximum size in bytes for a table that will be broadcast to all worker nodes when performing a join. Defaults to NULL to retrieve configuration entries.
