For 4: yea this is a problem, but I think it's not a big de
Hi Jakub,
Yea I think data source would be the most elegant way to solve your
problem. Unfortunately in Spark 2.3 the only stable data source API is data
source v1, which can't be used to implement high-performance data source.
Data source v2 is still a preview version in Spark 2.3 and may change
Hi Wenchen,
Thanks for your reply! We will have a look at the FileFormat.
Actually looking at the V2 APIs I still don’t see how you can use the existing
datasource (like Parquet + Hbase) and wrap it up in another one.
Imagine you would like to load some files from parquet and load some tables

Not much but still changed. I somehow agree that this is still manageable

Hi,
We're creating a new data source to fetch data from streaming source that
requires commiting received data and we would like to commit data once in a
while after it has been retrieved and correctly processed and then fetch
more.

In the master branch, we currently call this method in
ContinuousExecution.commit().
Note that the ContinuousReader API is experimental and undergoing active
design work. We will definitely include some kind of functionality to
