Work Description: regadas commented on issue #10869: [BEAM-9321] Add
BigQuery Avro logical type support on write
URL: https://github.com/apache/beam/pull/10869#issuecomment-593551872
Hi, I think we need to consider a few things:
1) in BigQuery this is not the default behavior; Users need to explicitly
enable `useAvroLogicalTypes` to have their types converted to the data types
mentioned in the doc as opposed to the underlying avro raw type. This means
that tables will have different schemas!
2) The previous Beam version was already released with this; Logical Types
are not respected and created Table will have schemas where types match the
avro raw types.
It makes sense that logical types should be respected by default (it option
to disable), but because of the previous points I don't think we can. or even
if it's a good idea.
