Tony Moulton updated BEAM-6654:
-------------------------------
Description:
Similar to HbaseIO.ReadAll, it would be very useful to support a SDF based
transform which can compose queries based off of input elements.
Implementation would split the work similarly to how the current Source API
implementation works (leveraging slices within Elasticsearch).
This work can facilitate a transition of ElasticsearchIO to SDF when more
runners have implemented support. Until then, I propose leaving the read()
implementation alone and add a readAll method and associated transform to be
implemented as an SDF. Once enough runner support is ready, the existing Read
transform would be updated to use the same SDF as the ReadAll transform with a
null input element.
A prototype implementation currently exists (albeit developed in a bubble) at
[https://github.com/0xdecaf/beam/tree/feature/elasticsearchio.readall]
