Feb 9, 2021
When a channel is created then, along with registering a state database, a query executor provider is also registered. The query executor provider returns query executors with and without a ledger lock. In some cases (such as with off-ledger and transient data) a ledger lock is not required and this will improve performance when reading data. closes trustbloc#291 Signed-off-by: Bob Stasyszyn <[email protected]>

Currently, the peer ledger function, NewQueryExecutor, acquires a read lock on the ledger which means that the caller needs to wait for any pending commit. In some cases, such as with off-ledger collections, the client does not require a lock on the ledger. The peer should expose a resource that allows a client to ask for a query executor that does not lock the ledger.
