@jrmccluskey , I meet a issue want to reference BigQueryEnrichementHandler to generate a SpannerEnrichemenetHandler.

Could you please help check how can batch list data can be received in def call(self, request: Union[beam.Row, list[beam.Row]], *args, **kwargs): method in SpannerEnrichemenetHandler()
I want to use EnrichemenetHandler to handle batch element instead of one by one beam. raw element, but when I put input data as below list, the data still comes to handler one by one. requests = [
beam.Row(sale_id=1, Consumer_Id='0b47c98f-58bf-4ae6-8577-9257f14ee7e6', product_id=1, quantity=1),
beam.Row(sale_id=3, Consumer_Id='e687e75a-d4be-411b-9301-4777183b2611', product_id=2, quantity=3),
beam.Row(sale_id=5, Consumer_Id='5c17e957-ceea-4ab9-a9d9-2d9f84c91380', product_id=4, quantity=2)
]

Create pipline as below approach

spanner_handler = SpannerMultiLineEnrichmentHandler(
project=project_id,
instance_id=instance_id,
database=database,
row_restriction_template=row_key + " ='{}'",
table_name=table_id,
fields=fields,
min_batch_size=3,
max_batch_size=3)

with beam.Pipeline() as p:
    _ = (
            p
            | "Create" >> beam.Create(requests)
            | "Enrich W/ Spanner" >> Enrichment(spanner_handler)
            | "Print" >> beam.Map(print))

I just want to get batch beam.raw list one time instead of one by one, please help on it, thanks.

Hey @lianliangzhang in general it is probably better to create a GitHub issue to discuss questions like this - could you please open one here and tag me, @jrmccluskey , and @claudevdm ? Please include the code you are currently using to define SpannerMultiLineEnrichmentHandler.
