I am trying to generate custom data files , but I could not.

My code : ./vmart_gen store_sales_fact1.tbl --files 3

I would like to divide my file into 3 files. How?

Hi!

From Docs:

Step 8: (Optional) Generate Custom Data Files
...
Splits the fact table data into the specified number of files. By default, the data generator produces a single, unnumbered fact table data file. If you specify a value of two (2) or more, the data generator numbers the files by appending an underscore character (_) and three digits to the file name, starting at _001. For example:

./vmart_gen --files 3

produces:

VMart_Fact_001.tbl
VMart_Fact_002.tbl
VMart_Fact_003.tbl

Default: 1

You do not specifies a table, generator do it automatically for FACT table.

Example of cmd:

Code: Select all

./vmart_gen \
--files 3
--datadirectory /tmp/VMart
--seed 9999
--time_file /path/to/time_file.txt \
--inventory_fact 100000 \
--customer_dimension 500 \
--date_dimension 500 \
--employee_dimension 50 \
--product_dimension 500 \
--promotion_dimension 500 \
--shipping_dimension 500 \
--vendor_dimension 500 \
--warehouse_dimension 500 \
--promotion_dimension 100
