Struct mz_transform::dataflow::DataflowMetainfo
source · pub struct DataflowMetainfo<Notice = RawOptimizerNotice> {
pub optimizer_notices: Vec<Notice>,
pub index_usage_types: BTreeMap<GlobalId, Vec<IndexUsageType>>,
}
Expand description
Extra information about the dataflow. This is not going to be shipped, but has to be processed in other ways, e.g., showing notices to the user, or saving meta-information to the catalog.
Fields§
§optimizer_notices: Vec<Notice>
Notices that the optimizer wants to show to users.
For pushing a new element, use Self::push_optimizer_notice_dedup
.
index_usage_types: BTreeMap<GlobalId, Vec<IndexUsageType>>
What kind of operation (full scan, lookup, …) will access each index. Computed by
prune_and_annotate_dataflow_index_imports
.

impl<Notice> DataflowMetainfo<Notice>
sourcepub fn used_indexes<T>(&self, df_desc: &DataflowDescription<T>) -> UsedIndexes
pub fn used_indexes<T>(&self, df_desc: &DataflowDescription<T>) -> UsedIndexes
Create a UsedIndexes
instance by resolving each id
in the
index_ids
iterator against an entry expected to exist in the
DataflowMetainfo::index_usage_types
.

T: Into<RawOptimizerNotice>,
pub fn push_optimizer_notice_dedup<T>(&mut self, notice: T)where
T: Into<RawOptimizerNotice>,
Pushes a RawOptimizerNotice
into Self::optimizer_notices
, but
only if the exact same notice is not already present.
