Examples with Row org.apache.cassandra.distributed.api.Row used on opensource projects

Example 1 with Row

use of org.apache.cassandra.distributed.api.Row in project cassandra by apache.

the class DistributedRepairUtils method validateExistingParentRepair.

private static void validateExistingParentRepair(QueryResult rs, Consumer<Row> fn) {
    Assert.assertTrue("No rows found", rs.hasNext());
    Row row = rs.next();
    Assert.assertNotNull("parent_id (which is the primary key) was null", row.getUUID("parent_id"));
    fn.accept(row);
    // make sure no other records found
    Assert.assertFalse("Only one repair expected, but found more than one", rs.hasNext());
}

Example 2 with Row

use of org.apache.cassandra.distributed.api.Row in project cassandra by apache.

the class DistributedRepairUtils method queryParentRepairHistory.

public static QueryResult queryParentRepairHistory(ICluster<IInvokableInstance> cluster, int coordinator, String ks, String table) {
    // This is kinda brittle since the caller never gets the ID and can't ask for the ID; it needs to infer the id
    // this logic makes the assumption the ks/table pairs are unique (should be or else create should fail) so any
    // repair for that pair will be the repair id
    Set<String> tableNames = table == null ? Collections.emptySet() : ImmutableSet.of(table);
    QueryResult rs = retryWithBackoffBlocking(10, () -> cluster.coordinator(coordinator).executeWithResult("SELECT * FROM system_distributed.parent_repair_history", ConsistencyLevel.QUORUM).filter(row -> ks.equals(row.getString("keyspace_name"))).filter(row -> tableNames.equals(row.getSet("columnfamily_names"))));
    return rs;
