getNeverLeasedShards

protected List<String> getNeverLeasedShards(List<String> requestedShards)
                                     throws ExecutionException,
                                            InterruptedException

Given a list of requested shards, return all which don't yet have a lease record in the connected dynamo DB.

Parameters:

requestedShards - a list of shardIDs to check against DynamoDB

Returns:

a list of shards never leased

Throws:

ExecutionException - - in case any of the Async calls fails, this will always wraps the real exception, unwrap it if you need to know what exactly failed

InterruptedException - - In case the entire thread was interrupted
