Enum mz_dataflow_types::sources::KeyEnvelope
source · [−]pub enum KeyEnvelope {
None,
Flattened,
LegacyUpsert,
Named(String),
}
Expand description
Whether and how to include the decoded key of a stream in dataflows
Variants
None
Never include the key in the output row
Flattened
For composite key encodings, pull the fields from the encoding into columns.
LegacyUpsert
Upsert is identical to Flattened but differs for non-avro sources, for which key names are overwritten.
Named(String)
Always use the given name for the key.
- For a single-field key, this means that the column will get the given name.
- For a multi-column key, the columns will get packed into a
ScalarType::Record
, and that Record will get the given name.
