To execute the sequence we created in the previous section, use the TableAPI.execute() method:

package kvstore.basicExample;
try {
    tableH.execute(opList, null);
} catch (OperationExecutionException oee) {
    // Some error occurred that prevented the sequence
    // from executing successfully. Use
    // oee.getFailedOperationIndex() to determine which
    // operation failed. Use oee.getFailedOperationResult()
    // to obtain an OperationResult object, which you can
    // use to troubleshoot the cause of the execution
    // exception.
} catch (IllegalArgumentException iae) {
    // An operation in the list was null or empty.

    // Or at least one operation operates on a row
    // with a shard key that is different
    // than the others.

    // Or more than one operation uses the same key.
} catch (DurabilityException de) {
    // The durability guarantee could not be met.
} catch (RequestTimeoutException rte) {
    // The operation was not completed inside of the
    // default request timeout limit.
} catch (FaultException fe) {
    // A generic error occurred
} 

Note that if any of the above exceptions are thrown, then the entire sequence is aborted, and your data will be in the state it would have been in if you had never executed the sequence at all.

TableAPI.execute() can optionally take a WriteOptions class instance. This class instance allows you to specify:

For an example of using WriteOptions, see Durability Guarantees.
