The manual says:
The following update operations are supported by Tarantool:
• ``'='`` – assign new value to the field
• ``'+'`` – add argument to the field (*both arguments are treated as signed 32-bit ints*)
• ``'^'`` – bitwise AND (*only for 32-bit integers*)
• ``'|'`` – bitwise XOR (*only for 32-bit integers*)
• ``'&'`` – bitwise OR (*only for 32-bit integers*)
• ``'splice'`` – implementation of `Perl splice <http://perldoc.perl.org/functions/splice.html>`_ function
The above is missing the following supported operations: '-' (subtraction), '#' (delete) and '!' (insert).
