[−][src]Enum declarative_dataflow::QuerySupport
Attributes might only appear in certain classes of queries. If that is the case, indexing overhead can be reduced.
Variants
Basic
Simple pull queries and star-joins require only a single index.
Delta
Delta queries require an additional index for validation of proposals.
AdaptiveWCO
Adaptive, worst-case optimal queries require three indices per direction, one for proposals, one for validation, and one for per-key statistics.
