explore feels slow in big tables

[amtoine]

i think the TUI renders every row of the data, even if it's out of the screen 🤔

this means that a table with 15000 rows will feel much slower than the first 100 lines of the same table.

if the history is big enough, one can compare

open $nu.history-path | query db "SELECT * from history" | first 20000 | explore

and

open $nu.history-path | query db "SELECT * from history" | first 200 | explore

alternately, one can use the following command to generate a dummy table of a certain length

def t [n: int] {
    let ids = seq 1 $n | each { random uuid } | wrap id
    let names = seq 1 $n | each { random chars --length 64 } | wrap name
    let vals = seq 1 $n | each { random int } | wrap val

    $ids | merge $names | merge $vals
}

it starts to feel slightly slow with t 10_000, and it gets worse with t 20_000 and t 30_000 freezes.

Note

also works with seq 1 $n with $n = 10^{5}$
