Module mz_storage::source

Types related to the creation of dataflow raw sources.

Raw sources are streams (currently, Timely streams) of data directly produced by the upstream service. The main export of this module is create_raw_source, which turns RawSourceCreationConfigs and SourceConnections implementations into the aforementioned streams.

The full source, which is the differential stream that represents the actual object created by a CREATE SOURCE statement, is created by composing create_raw_source with decoding, SourceEnvelope rendering, and more.

Modules

• generator
• kafka 🔒
• mysql 🔒
  Code to render the ingestion dataflow of a MySqlSourceConnection.
• postgres 🔒
  Code to render the ingestion dataflow of a PostgresSourceConnection. The dataflow consists of multiple operators in order to take advantage of all the available workers.
• reclock 🔒
• source_reader_pipeline 🔒
  Types related to the creation of dataflow raw sources.
• statistics 🔒

  Types related to the source ingestion pipeline/framework.

Structs

• KafkaSourceReader
  Contains all information necessary to ingest data from Kafka
• RawSourceCreationConfig
  Shared configuration information for all source types. This is used in the create_raw_source functions, which produce raw sources.
• SourceExportCreationConfig
  Reduced version of RawSourceCreationConfig that is used when rendering each export.

Functions

• create_raw_source
  Creates a source dataflow operator graph from a source connection. The type of SourceConnection determines the type of connection that should be created.
