setAll

public IcebergSource.Builder<T> setAll(java.util.Map<java.lang.String,java.lang.String> properties)

watermarkColumn

public IcebergSource.Builder<T> watermarkColumn(java.lang.String columnName)

Emits watermarks once per split based on the min value of column statistics from files metadata in the given split. The generated watermarks are also used for ordering the splits for read. Accepted column types are timestamp/timestamptz/long. For long columns consider setting watermarkColumnTimeUnit(TimeUnit).

Consider setting `read.split.open-file-cost` to prevent combining small files to a single split when the watermark is used for watermark alignment.

watermarkColumnTimeUnit

public IcebergSource.Builder<T> watermarkColumnTimeUnit(java.util.concurrent.TimeUnit timeUnit)

When the type of the watermarkColumn(java.lang.String) is Types.LongType, then sets the TimeUnit to convert the value. The default value is TimeUnit.MICROSECONDS.

properties

@Deprecated
public IcebergSource.Builder<T> properties(java.util.Map<java.lang.String,java.lang.String> properties)

Deprecated.

Use setAll(java.util.Map<java.lang.String, java.lang.String>) instead.

build

public IcebergSource<T> build()

buildStream

public org.apache.flink.streaming.api.datastream.DataStream<T> buildStream(org.apache.flink.streaming.api.environment.StreamExecutionEnvironment env)

Build the IcebergSource and create a DataStream from the source. Watermark strategy is set to WatermarkStrategy.noWatermarks().

Returns:

data stream from the Iceberg source
