How many bytes does a chunk equal to?

hi, I am using the C API :
auto future = fdb_transaction_get_range_split_points(tr, start.data, start.dataLen, end.data, end.dataLen,
chunkSize);
I want to know how many bytes does a chunk equal to ?

That’s a parameter you specify according to your needs, e.g 10000000 for 10 megs, and it will create splitpoints with 10 meg sized chunks between the start and end you specified.

Oh,I get it ~ Thanks!
