does anyone have any documentation on how to interpret the result of an explain ? I’m trying to improve some quite sophisticated xqueries so as to add any necessary index, but there is so many information in the result of the explain, it’s possible I miss some points in it.
Look out for the database scan operators, to get an idea of the interaction between the XQuery engine and the database:
- XqcUnnestCollectionScan - retrieve all documents of a collection
- XqcUnnestDoctypeScan - retrieve all documents of a doctype
- XqcUnnestStdIdxScan - retrieve documents qualified by index access using given predicates
- XqcUnnestFullIdxScan - retrieve values stored in a given index
