mapreduce.yaml and NDB filters

[Moisés Belchín]

Hi all,

I'm using mapreduce library with pipelines and filters and NDB models. Everthing works very well !

My question:

Is it possible define filters in mapreduce.yaml file ? Like this:

mapreduce:

- name: Re-index

  mapper:

    input_reader: mapreduce.input_readers.DatastoreInputReader

    handler: mr.review_entities

    params:

    - name: entity_kind

      default: model.Entities

    - name: shard_count

      default: 20

    - name: queue_name

      default: fastest

    - name: filters

      default: [("status", "=", "ACTIVE")]

I have found however than in my case, I had to write the filters as a String containing a list of lists rather than a List of Tuple.

So if this does not work:

default: [("status", "=", "ACTIVE")]

Try:

default: '[["status", "=", "ACTIVE"]]'
