Hi All,
Can I specify watermark using raw sql alone? other words without using
.withWatermark from
Dataset API.
Thanks!
Hi,
I could not find useful formula or documentation which will help me to
decide the broadcast join data size depends on the cluster size.
Please let me know is there thumb rule available to find.
For example
cluster size - 20 node cluster, 32 gb per node and 8 core per node.

No, streaming dataframe needs to be written to disk or similar (or an in-memory
backend) then when the next stream arrive join them - create graph and store
the next stream together with the existing stream on disk etc.

For your use case one might indeed be able to work simply with incremental
graph updates. However they are not straight forward in Spark. You can union
the new Data with the existing dataframes that represent your graph and create
from that a new graph frame.
However I am not sure if this will
