how does browser paging work for the following?

  • queries in the url

(num: til 1000)

http://localhost:5001/?([]num:%20til%201000)

  • hdb/partitioned/segmented

  • rdb

does kdb keep any of these?

a. cursor

b. cookie

c. handle

d. page number

e. in-memory table/resultset

f. no in-memory table but re-evaluate the expression and show row[i] to row[i + page size - 1]

Hi,

the default implemantation of .z.ph (done in q.k) stores your query (you query with  /?<QUERY> ) in a variable called .h.R

when you use  pagination afterwards with /?[<offset>   the query in R is reevaluated.

just enter .z.ph to see the code its just some lines.

the .h.jx function is doing the pagination.
