                             long startupTimestampMillis)

Creates a Kafka 0.10 StreamTableSource.

参数:

outputDataType - Source output data type

topic - Kafka topic to consume

properties - Properties for the Kafka consumer

decodingFormat - Decoding format for decoding records from Kafka

startupMode - Startup mode for the contained consumer

specificStartupOffsets - Specific startup offsets; only relevant when startup mode is StartupMode.SPECIFIC_OFFSETS

startupTimestampMillis - Startup timestamp for offsets; only relevant when startup mode is StartupMode.TIMESTAMP
