index_object:min()

object index_object

index_object:min([key])

Find the minimum 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 first key in the index. If optional `key` value is supplied, returns the first key which is greater than or equal to `key` value. In a future version of Tarantool, index:min(`key` value) will return nothing if `key` value is not equal to a 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:min()
---
- ['Alpha!', 55, 'This is the first tuple!']
