Description copied from interface: CoreQueryOps

Performs a query. This can handle single-query transactions.

Specified by:

queryBlocking in interface CoreQueryOps

Parameters:

statement - the statement to execute

options - query options

queryContext - non-null iff this query is on a Scope

target - this is required for some use-cases (transactions, notably, where all queries in a transaction attempt must be sent to the same node). The way targets are identified is currently very bound to Classic, and will need to be abstracted if we need to support the same functionality for Protostellar ultimately. However, the nature of Protostellar makes that unlikely.

errorConverter - required for converting Core errors into their final SDK forms. (It could be handled externally in most cases, but this DRYs the logic, and there is at least one transactions use-case that requires doing this conversion on the rows as they stream back.
