I would use 8 if I have max_write_buffer_number set to 8 as each
write_buffer will have it's own WAL. If max_write_buffer_number is 1 I
would use recycle_log_file_num=1.

Do you have any reason for this value? :))

With ceph I have always used it to set the number of WALs to recycle,
ie to recycle 8 WALs I use:
"
recycle_log_file_num=8
"

Yes here I found it’s a boolean (= true)
Will this true convert to 1?

Options.recycle_log_file_num = true will keep a pool of WAL files and
try to reuse them. When writing to an existing log file, random writes
are used from size 0. Before writes hit the end of the file, the file
size doesn't
I believe it is the number of WALs that should be reused and should be
equal to write_buffer_number but don't quote me.
