Loopback translator

The Loopback translator, known by the type name loopback, provides a quick testing solution. It works with all SQL constructs and returns default results, with some configurable behavior.

Table 1. Execution properties
Name Description Default


true to always throw an error.



Rows returned for non-update queries.



Wait randomly up to this number of milliseconds with each source query.



If positive, results will be asynchronously returned — that is a DataNotAvailableException will be thrown initially and the engine will wait the poll interval before polling for the results.



Set to the name of the translator which is to be mimicked.


You can also use the Loopback translator to mimic how a real source query would be formed for a given translator (although loopback will still return dummy data that might not be useful for your situation). To enable this behavior, set the DelegateName property to the name of the translator that you want to mimic. For example, to disable all capabilities, set the DelegateName property to jdbc-simple.
