It is desired that Modeler documentation contain more detailed discussion of what nodes or node functions are supported with pushback when working with Analytic Server, specifically as it relates to what nodes pushback only to Analytic Server and which nodes will pushback to the cluster itself with respect to different data sources (HDFS/Hive/HCatalog/BigSQL/etc). Currently it comes as a surprise to users when a node properly pushes back to Analytic Server, but not fully back to the entire cluster and they see reduces performance from their expectations, perhaps based on the data source used.
Further to this the SQL Preview button currently provides feedback indicating if the nodes in the stream support pushback to Analytic Server or not, but do not color the stream as is seen when using ODBC data sources. Colored visual feedback for AS data sources would be a plus, perhaps using one color to indicate AS pushback and yet another to indicate full pushback to the underlying data source (i.e. past AS).
