Question

When running queries on the ledger, how do simple keys differ from composite keys?

A Simple keys and composite keys are not used when executing queries on the ledger.
B Simple keys allow for more complex queries than composite keys.
C Composite keys allow for more complex queries than simple keys.
D Simple keys and composite keys function the same way when executing queries on the ledger.

Explanation

Composite keys combine multiple attributes and can be modeled to support equivalence queries across multiple parameters; a simple key identifies an individual state entry. This makes composite keys more capable for key-based query patterns. ოფიციal Hyperledger Fabric documentation describes composite keys as enabling equivalence queries against multiple parameters.
