azure stream analytics - Strange powerbi behaviour cannot explore dataset -

i sending data stream analytics powerbi. of time works fine time time upload large amounts of data test purposes. notice su utilization 100% , error messages in stream analytics saying might encounter strange behaviour because of that. , in of these cases when goto powerbi see datasets when try explore them nothing. table page not opened.

powerbi in preview, , there still silent bugs here , there.

two silent bugs come mind are:

1. powerbi not support embedded json objects. if single entry goes powerbi has embedded object, break entire table.

2. table schemas set in stone. if later decided wanted change schema (by changing select statement in stream analytics), have output entirely different table. if 2 different schemas go same table, table break , fail load have mentioned.
