Work Description: rezarokni commented on pull request #9032: [BEAM-7386]
Bi-Temporal Join
URL: https://github.com/apache/beam/pull/9032
The extentions/timeseries is intended to be a incubation area for utilities
that assist with working with time series data
This sample will take two streams left stream and right stream. It will
match the left stream to the nearest right stream based on their timestamp.
Nearest left stream is either <= to the right stream timestamp.
