Please change your query to improve its efficency:
Your queries should take less than 5 seconds: - Use the 'pointDirection' parameter
- Don't use the 'pointKey' parameter without the 'operatorKey' parameter.
- Don't use the 'sort' parameter for automatic and/or large queries.
- Don't query data for a large range of days.
Also, please do not make multiple concurrent call to our api (avoid multi-threads, multi-instances, multi-servers, ...)
