pub enum AccessStrategy {
UnknownOrLocal,
Persist,
Index(Vec<(GlobalId, IndexUsageType)>),
SameDataflow,
}
Expand description
For a global Get, this indicates whether we are going to read from Persist or from an index. (See comment in MirRelationExpr::Get.)
Variants§
UnknownOrLocal
It’s either a local Get (a CTE), or unknown at the time.
prune_and_annotate_dataflow_index_imports
decides it for global Gets, and thus switches to
one of the other variants.
Persist
The Get will read from Persist.
Index(Vec<(GlobalId, IndexUsageType)>)
The Get will read from an index or indexes: (index id, how the index will be used).
SameDataflow
The Get will read a collection that is computed by the same dataflow, but in a different
