Run a streaming Action and return an Iterator which performs blocking I/O on the current
thread (if supported by the Database) or blocks the current thread while waiting for the
next result.
Run an Action and block the current thread until the result is ready.
Run an Action and block the current thread until the result is ready. If the Database uses synchronous, blocking excution, it is performed on the current thread in order to avoid any context switching, otherwise execution happens asynchronously.
Some utility methods for working with database results in a synchronous or blocking way that can be detrimental to performance when used incorrectly.
