Example

PQL

input = ACCESS({source='Source',
wrapper='GenericPush',
transport='TCPServer',
protocol='CSV',
dataHandler='Tuple',
options=[['port', '8080'],['read', '10240'],['write', '10240']],
schema=[
['id', 'Double'],
['data', 'String']]
})

output = SENDER({sink='Sink',
wrapper='GenericPush',
transport='TCPServer',
protocol='CSV',
dataHandler='Tuple',
options=[['port', '8081'],['read', '10240'],['write', '10240']]
}, input)
