previously we parsed/returned large sections of the documents back index row in order to compute facet information. this would require parsing the protobuf of the entire back index row. unfortunately this creates considerable garbage. this new version introduces a visitor/callback approach to working with data inside the back index row. the benefit of this approach is that we can let the higher-level code see values, prior to any copies of data being made or intermediate garbage being created. implementations of the callback must copy any value which they would like to retain beyond the callback. NOTE: this approach is duplicates code from the automatically generated protobuf code NOTE: this approach assumes that the "field" field be serialized before the "terms" field. This is guaranteed by our currently generated protobuf encoder, and is recommended by the protobuf spec. But, decoders SHOULD support them occuring in any order, which we do not. |
