The # operator in Lua means “return count of components”. So, if t is a tuple instance, #t will return the number of fields.

Rtype:number

In the following example, a tuple named t is created and then the number of fields in t is returned.

tarantool> t = box.tuple.new{'Fld#1', 'Fld#2', 'Fld#3', 'Fld#4'}
---
...
tarantool> #t

- 4
