Jacob Ferriero updated BEAM-9856:
---------------------------------
Description:
Currently the List Messages API paginates through in a single ProcessElement
Call.
However we could get a restriction based on createTime using Messages.List
filter and orderby.
This is inline with the future roadmap of HL7v2 bulk export API becomes
available that should allow splitting on (e.g. create time dimension).
Leveraging this bulk export might be a future optimization to explore.
This could look like paginating through each hour of data w/ in the time frame
that the store spans, in a separate thread.
was:
Currently the List Messages API paginates through in a single ProcessElement
Call.
In the future if a bulk export API becomes available that would allow splitting
on some dimension (e.g. create time), this should be refactored as a splittable
DoFn or at least run several sub queries so that we are not listing an entire
store in a single thread.
This could look like paginating through each hour of data w/ in the time frame
that the store spans, in a separate thread.
