Re: The received uncompressed data on the gateway client has exceeded limit.

Hi @iJuancho - nice work - what were the data types before you changed them?

Re: The received uncompressed data on the gateway client has exceeded limit.

In my case, The data type changes I made were:

 

- 9 columns of INT (4 bytes) to TINYINT (1 byte) => 45 millions * 9 columns * 4 bytes = 1.5Gb vs 386MB

- 5 columns of INT to SMALLINT (2 byte) => 45 millions * 5 columns * 4 bytes = 858Mb vs 429MB

- 4 columns of DECIMAL(14, 6) (13 bytes) to SMALLMONEY (4 bytes) = 45 millions * 4 columns * 13 bytes = 2.2Gb vs 686Mb

- 1 column of Varchar(50) to Varchar(30) = 2.1Gb vs 1.2Gb

 

If we add the changes these give us:

Before = 6.6GB

After = 2.7Gb

 

Finally, my fact table has a UNION between Sql Server and Oracle. When defining my Sql Server table as primary, Power BI takes the metadata of the primary table and forces data coming from Oracle to have that same data type.

Re: The received uncompressed data on the gateway client has exceeded limit.

Hi @iJuancho

 

It appears I will need to investigate the same approach you did in reducing the data sizes. See our response from MS here: 

http://community.powerbi.com/oxcrx34285/board/message?board.id=power-bi-web-app&message.id=27670#M27...

 

So the data type changes you made below... did you make them at the database table level or did you change their type in a SQL view or Stored Procedure? 

 

Thank you
