[Anonymous]

HI,

But most of the time was failed, i am getting error like "ERROR[HY000] [Simba][Athena](1120) An unexpected error has occurred during stream read.it could be caused by the stream buffer exceeded its maximum capacity.please consider lowering the RowsToFetchPerBlock value and try again.[Execution ID:0d3c8d08-c474-474d-be67-7e7c9d2b36dd][Failbit:1][Badbit: 0][Eof:1]"

In the configuration of the Odbc Driver Row ToFetchPerBlock is montioned 10000.

Hi Pardiles,

We raised the ticket with the microsoft support team,but we didn't get the proper solution, they are saying try to reduce the Row To Fetch Count only

our case we maintined 7k  As "Row to Fetech Count" then refresh  was worked properly

Thanks!!

Hi @Anonymous ,

Have you tried lowering the RowsToFetchPerBlock value or reducing the frequency of refresh?
