Module mz_storage::source

source ยท
Expand description

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.

Modulesยง

  • kafka ๐Ÿ”’
  • mysql ๐Ÿ”’
    Code to render the ingestion dataflow of a MySqlSourceConnection.
  • postgres ๐Ÿ”’
    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 ๐Ÿ”’
    Operators that transform collections that evolve with some timestamp FromTime into a collections that evolve with some other timestamp `IntoTime.
  • Types related to the creation of dataflow raw sources.
  • statistics ๐Ÿ”’
  • Types related to the source ingestion pipeline/framework.

Structsยง

  • Contains all information necessary to ingest data from Kafka
  • Shared configuration information for all source types. This is used in the create_raw_source functions, which produce raw sources.

Functionsยง

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