Artem Malykh created IGNITE-10297: ------------------------------------- Summary: Investigate possibility of restricting API of Upstream transformer Key: IGNITE-10297 URL: https://issues.apache.org/jira/browse/IGNITE-10297 Project: Ignite Issue Type: Improvement Components: ml Reporter: Artem Malykh Assignee: Artem Malykh
Signature of 'transform' method of UpstreamTransformer is Stream<UpstreamEntry> -> Stream<UpstreamEntry>. For now it is used only for bagging and for that purpose, UpstreamEntry -> Stream<UpstreamEntry> would suffice (just use 'flatMap' on upstream), maybe we should change signature to this form. From other hand, we'll cut some possibilities like limiting of upstream. This question needs investigation. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
