Struct ProjectionSpec 

pub struct ProjectionSpec {
    pub name: String,
    pub table: String,
    pub group_keys: Vec<usize>,
    pub aggregates: Vec<ProjectionAggregate>,
    pub filter_signature: Option<String>,
}

Fields

name: String

table: String

Table the projection is attached to.

group_keys: Vec<usize>

Columns (by index in the parent table schema) used as group keys.

aggregates: Vec<ProjectionAggregate>

Aggregates materialised in this projection.

filter_signature: Option<String>

Optional pre-applied filter — e.g. WHERE env = 'production'. Represented as a canonical string because the matcher only needs equality on the serialised form; a richer AST comparison can plug in later.
