Denis Magda commented on IGNITE-7655:
-------------------------------------

[~NIzhikov] , thanks for the explanation! It helped. Unfortunately, I don't see 
the changes (plus there are some TODOs left on the page). Akmal told me he had 
troubles with the same page earlier today. Probably, that's because you both 
might have been editing it at the same time. 

Could you have a look and update the doc one more time? Please make sure this 
option below is documented:

{{SaveMode.Append}} + {{OPTION_STREAMER_ALLOW_OVERWRITE=true}}

The problem with the existing Scala examples is that they are added to the 
folder of Java examples:

[https://github.com/apache/ignite/tree/master/examples/src/main/spark/org/apache/ignite/examples/spark]

while they need to be here:

[https://github.com/apache/ignite/tree/master/examples/src/main/scala/org/apache/ignite/scalar/examples/spark]

If it's not late to merge the changes to 2.4, please fix it. Ask the community 
for permission. Otherwise, create a ticket for 2.5.

Also, we need to have examples of Java API usage. If you don't have anything 
ready, then Akmal can create Java versions of the Scala example for 2.5.
