Hi [~jbernste]
Thanks for your feedback. I looked at
[https://solr.apache.org/guide/8_11/transform.html#paging]. Paging can be
implemented with this stream function.
However In my experiment, performance of *PagingStream* seems much better
compared to {*}stream functions (recNum gt, lt){*}.
e.g. *StreamFunction approach took 1872 ms.*
{code:java}
having(
select(
search(order_details, q="product_id:[1 TO
1000000]",qt="/export",fl="id,qty",sort="qty desc"),
id,
qty,
recNum() as recNum),
and (gt(recNum, 0),lt(recNum, 11))
){code}
where *Paging Stream took 1044 ms*
{code:java}
page(start=1,rows=10,
search(order_details, q="product_id:[1 TO
1000000]",qt="/export",fl="id,qty",sort="qty desc"),
sort=qty desc){code}
