How to optimize below tables load time.

FROM
(ooxml, embedded labels, table is Sheet1);

Hi,
Looks like there is issue in your joining field.
Provide xls sheet to understand issue.

otherwise chk here
Hi,
Instead of join use Mapping Load and ApplyMap() like below if they are one-to-one.
Product_Group_Mapping:
MAPPING LOAD product_group,
bucket
FROM
(ooxml, embedded labels, table is Sheet1)
WHERE 1 = 1;
TemP:
LOAD Date,
product_group,
ApplyMap('Product_Group_Mapping', product_group, 'N/A') AS bucket
FROM
(ooxml, embedded labels, table is Sheet1);
Hope this helps you.
Regards,
Jagan.
Hi,
I do not know how many times you need to reload but I would suggest that load that data into QVD files and then load the main app from the QVD files. QVD files should reload faster but this all depends on how often the excel file is updated
hi,
you can also do like
TemP:
LOAD Date,
product_group
FROM
(ooxml, embedded labels, table is Sheet1);
Left join(TemP)
LOAD product_group,
bucket
FROM
(ooxml, embedded labels, table is Sheet1)
where exists(product_group);
