Timo Walther created FLINK-8240: ----------------------------------- Summary: Create unified interfaces to configure and instatiate TableSources Key: FLINK-8240 URL: https://issues.apache.org/jira/browse/FLINK-8240 Project: Flink Issue Type: New Feature Components: Table API & SQL Reporter: Timo Walther Assignee: Timo Walther
At the moment every table source has different ways for configuration and instantiation. Some table source are tailored to a specific encoding (e.g., {{KafkaAvroTableSource}}, {{KafkaJsonTableSource}}) or only support one encoding for reading (e.g., {{CsvTableSource}}). Each of them might implement a builder or support table source converters for external catalogs. The table sources should have a unified interface for discovery, defining common properties, and instantiation. The {{TableSourceConverters}} provide a similar functionality but use a external catalog. We might generialize this interface. In general a table source declaration depends on the following parts: - Source - Type (e.g. Kafka, Custom) - Properties (e.g. topic, connection info) - Encoding - Type (e.g. Avro, JSON, CSV) - Schema (e.g. Avro class, JSON field names/types) - Rowtime descriptor/Proctime - Watermark strategy and Watermark properties - Time attribute info - Bucketization This issue needs a design document before implementation. Any discussion is very welcome. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
