There is a JDBC table sink, but it only supports append mode (via INSERTs). The CSVTableSource is for reading data from CSV files, which can then be processed by Flink. If you want to operate on your data in batches, one approach you could take would be to export the data from Postgres to CSV, and then use a CSVTableSource to load it into Flink. interface TableEnvironment { /** reads a table from the given descriptor */ Table from (TableDescriptor tableDescriptor); // we already have a "from (String)" method to get registered table from catalog } interface Table { /** Writes the Table to a sink that is specified by the given descriptor. t_env.register_function("data_converter", udf(DataConverter(), input_types = [DataTypes.STRING()], result_type = DataTypes.ROW([ DataTypes.FIELD("feature1", DataTypes.STRING()) ]))) t_env.from_path(INPUT_TABLE) \ .select("monitorId, time, data_converter(data)") \ .insert_into(OUTPUT_TABLE) t_env.execute("IU pyflink job") This patch will wrap the flink's DataStream as a StreamTable, which could allow user to use SQL to insert records to iceberg table, it will try to provide the similar experience with spark sql. Currently, this patch is depending on #1185.

However Flink does not provide a sink API to guarantee the exactly once semantics in both bounded and unbounded scenarios, which blocks the unification. So we want to introduce a new unified sink API which could let the user develop sink once and run it everywhere. Specifically Flink allows the user to
