ExecutionInfo Class |
Basic information on the execution of a query.
This provides the following information on the execution of a (successful) query:
- The list of Cassandra hosts tried in order (usually just one, unless a node has been tried but was dead/in error or a timeout provoked a retry (which depends on the RetryPolicy)).
- The consistency level achieved by the query (usually the one asked, though some specific RetryPolicy may allow this to be different).
- The query trace recorded by Cassandra if tracing had been set for the query.

| QueriedHost |
Retrieves the coordinator that responded to the request
|
| QueryTrace |
Gets the trace for the query execution.
|
| TriedHosts |
Gets the list of host that were queried before getting a valid response,
