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.
