Class FlinkWriteConf


  • public class FlinkWriteConf
    extends java.lang.Object
    A class for common Iceberg configs for Flink writes.

    If a config is set at multiple levels, the following order of precedence is used (top to bottom):

    1. Write options
    2. flink ReadableConfig
    3. Table metadata
    The most specific value is set in write options and takes precedence over all other configs. If no write option is provided, this class checks the flink configuration for any overrides. If no applicable value is found in the write options, this class uses the table metadata.

    Note this class is NOT meant to be serialized.
