When using the RestlookupService, I could not find a way to specify any timeout configuration, as we can do in InvokeHTTP.
I wanted to use this lookup service in order to complete my record with datas given from external REST Service. But this service may takes time, almost 20 seconds.
The LookupService fires an exception because of read timeout.
I try to do a simple trick using InvokeHTTP, put the result in a DistributedMapCache and then try to use a LookupService to retrieve the returned record and inject it in the source. But does not work.
So my only solution for now is to work with the Merge and then using JoltTransformation.
