Best way to extract a CSV with aggregations


(Thomas) #1

Hi,

I was wondering what is the best way to extract a csv with the various
terms of some fields alongside with the corresponding counts? For example
create a csv as follows:

productId, product, category, city, hour, products_count,

selled_products_count

Will cat API be useful in this case? Or I have to pass from multiple
aggregation calls to construct this information?

Thanks
Thomas

You'll probably need to parse the JSON query results in your programming
language to constuct a CSV result yourself. No the CAT API has a different
purpose - it is used to display columnar views of cluster/index/node info
and statistics - not query results.
