org.apache.phoenix.util.CSVCommonsLoader.upsert()
Upserts data from CSV file. Data is batched up based on connection batch size. Column PDataType is read from metadata and is used to convert column value to correct type before upsert. The constructor determines the format for the CSV files. @param fileName @throws Exception
