Constant tarantool::space::SPACE_ID_MAX

pub const SPACE_ID_MAX: SpaceId = _; // 2_147_483_646u32

Maximum possible space id.

Note that on older versions of tarantool it’s actually possible to create a space with id 1 higher than this, but that value is also used as an error marker in some api functions so it realy shouldn’t be used as a valid space id. This value is used when creating spaces via this library, so we may prohibit you from creating a space with id which is valid on your tarantool version (but this is unlikely to cause problems).

You can also use box.schema.SPACE_MAX from lua to know for a fact what is the maximum allowed space id on your tarantool version.
