index_object:max()

object index_object¶

index_object:max([key])¶

Find the maximum value in the specified index.

Parameters:	index_object (index_object) – an object reference key (scalar/table) – values to be matched against the index key
Return:	the tuple for the last key in the index. If the optional key value is supplied, returns the last key that is less than or equal to key. Starting with Tarantool 2.0.4, index_object:max(key) returns nothing if key doesn’t match any value in the index.
Rtype:	tuple

Possible errors: index is not of type ‘TREE’.

Complexity factors: index size, index type.

Example:

tarantool> box.space.tester.index.primary:max()
---
- ['Gamma!', 55, 'This is the third tuple!']
