power bi store data in byte?

[Anonymous]

Hi,

i have one query for storing data in bytes.

for example if I am using SQL DB as datasource and in DB i use decimal (38,10) and int datattype columns.

at SQL DB front these columns take 17 byte and 4 byte for storing data value.

So, if I import this table in PBI desktop then what would be the size in bytes PBI stores.

Thanks,

Shubham

Hi @Anonymous,

In Power BI, VertiPaq stores each column in a separate data structure. This simple fact allows the engine to implement some extremely important compressions and encoding. Here is a good article about VertiPaq, which could help you understand how the VertiPaq engine stores data in Power BI.

Thanks @v-ljerr-msft for sharing, it is very informative and detailed document.

so consider this, I can say Power BI use VertPaq engine and it has many methods to compress the data and these methods would be applicable according to the nature of data.

Am I right ?
