Class TableSchema

java.lang.Object

org.apache.cassandra.spark.bulkwriter.TableSchema

public class TableSchema
extends java.lang.Object

Schema information for bulk write operations.

This class does NOT implement Serializable (Logger is not serializable). For broadcast to executors, BroadcastableTableSchema is used instead, and executors reconstruct TableSchema from the broadcastable data.
