When set to true, the provider will aggregate into a single table called AggregatedFiles all the files located in the URI directory which have the same schema.

Data Type

bool

Default Value

false

Remarks

By default, the first file in the folder is used to define the schema, however MetadataDiscoveryURI can be specified to use a different file instead.

Take for example the following CSV contents.

File 1

ItemID,Name,NumInStock
1,Peanuts - Salted,76
2,Peanuts - Unsalted,43
3,Raisins,26

File 2

ItemID,Name,NumInStock
4,Pretzels - Original,55
5,Pretzels - Chocolate,35
6,Toffee,44

The resulting aggregate table is shown below. Note that only the columns present in the defined schema are used in the aggregate.

AggregateFiles

ItemID,Name,NumInStock
1,Peanuts - Salted,76
2,Peanuts - Unsalted,43
3,Raisins,26
4,Pretzels - Original,55
5,Pretzels - Chocolate,35
