How to Stream Data Serialization in Olingo v2
Hi!!!
I have develop a OData Service using Olingo v2 ( i need this version, i
cann`t no use v4)
But some times muy dataset to return is huge, and I can not store it in the
List<Map<String, Object>>
that EntityProvider.writeFeed needs.
There is any workaround to avoid creating a huge List??? ( pagination is
not an option)

Hi Christina, thanks
I am reading de ODatav2 code. And I will to try to implement it (if it is
possible)
maybe you could give me some orientation
should I implement a new AtomEntityProvider writeFeed method
public ODataResponse writeFeed(final EdmEntitySet entitySet, final
List<Map<String, Object>> data,
final EntityProviderWriteProperties properties) throws
EntityProviderException
That instead of using l List<Map<String, Object>>
receive Stream?
or it is better a different aproach

Hi,
in Olingo V2 there is no streaming API. If pagination is not an option then I see no other way.
You could write your own serializer which is capable of doing this.
