[jira] [Created] (ZEPPELIN-1635) Performance issue of z.angularBind?

Cédric Hernalsteens created ZEPPELIN-1635:
---------------------------------------------

             Summary: Performance issue of z.angularBind?
                 Key: ZEPPELIN-1635
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-1635
             Project: Zeppelin
          Issue Type: Wish
          Components: zeppelin-interpreter
    Affects Versions: 0.6.2, 0.6.1, 0.6.0
            Reporter: Cédric Hernalsteens


I am binding with `z.angularBind` a Scala Array of Array of Floats (10 x 3000).

In case the value actually changed and is sent / processed by the client, it becomes extremely slow (10s). This cannot by explained by the network being a potential bottleneck.

Could someone with a more detailed understainding of the Zeppelin interpreters (and the Angular one), and/or Angular, suggest a performance test more detailed than what I measured?

Is this a problem potentially coming from Zeppelin?
