Set max parallelism using python SDK for N1QL query

I am using python sdk v2.5 to run N1QL queries. I want to set max parallelism for the query I am running. I tried using set_option command as below but this gives me following error.

query = N1QLQuery(cb_query)
query.timeout = 1200

errors’: [{‘code’: 1065, ‘msg’: ‘Unrecognized parameter in request: max-parallelism’}], ‘status’: ‘fatal’, ‘metrics’: {‘elapsedTime’: ‘157.358µs’, ‘executionTime’: ‘37.042µs’, ‘resultCount’: 0, ‘resultSize’: 0, ‘errorCount’: 1}}, http_status=400, tracing_context=0, tracing_output=None>, Tracing Output={":nokey:0": null}>

Please let me know how to go about this

try the max_parallelism
