Just added a Doctrine PreparedQueryExtractor

programarivm commented 6 years ago

Thanks for the review! QueryExtractor and PreparedQueryExtractor are merged now into AbstractExtractor if this makes more sense.

programarivm commented 6 years ago

Just added one more Doctrine example using a MapFieldsTransformer -- btw I won't push any more examples to this PR until the MapFieldsTransformer example is reviewed.

programarivm commented 6 years ago

The MapFieldsTransformer is temporarily removed from this PR
QueryExtractor and PreparedQueryExtractor are merged into QueryExtractor -- which is now a prepared query with 3 params with the third one being optional

programarivm commented 6 years ago

Yeah, it makes sense. $this->data can always be bigger and bigger. Perhaps that is a problem that may be addressed by splitting huge queries into smaller chunks to multiprocess them in parallel.
