supportsPathQueries property
true when this keystore can push value-field predicates
down to its native query plan (queryByPath is then a real
indexed query). false when queryByPath is unsupported
and consumers must fall back to a scanKeys + in-memory
filter.
Hive backends return false. A future SQL backend flips
this to true once it has defined the indexed-query schema.
Implementation
@override
bool get supportsPathQueries => false;
