Hey guys, I wanted to ask if I'm using the DocTransformer API as intended. There is a setContext( TransformerContext c ) method which is called by the TextResponseWriter before it calls transform on any docs. That context object contains a DocIterator reference. I want to use a DocTransformer to add info from DynamoDB based on the uniquekeys of docs, so I figured this would be the way to go to get all needed data from DDB in a batch before transform.
Turns out if you call nextDoc on that iterator, that doc will not be transformed because the iterator is not reset or regenerated in any way before transformations start being called. In some cases, if the Collector collected extra docs, the DocSlice will have more docids to return even after hasNext, and the code doesn't check that, so it will transform those. Then eventually it may throw an IndexOutOfBoundsException. My gut says this is not intended. Why not give the DocList in the TransformContext? So in the example solrconfig, I think there is a suggestion to use DocTransformers to get data from external DBs, but has anyone done this, and how do they handle making a single/batch request instead of doing one for every transform call?
