box.space._index

_index is a system space.

Tuples in this space contain the following fields:

• id (= id of space),
• iid (= index number within space),
• name,
• type,
• opts (e.g. unique option), [tuple-field-no, tuple-field-type ...].

Here is what _index contains in a typical installation:

 
tarantool> box.space._index:select{}---- - [272, 0, 'primary', 'tree', {'unique': true}, [[0, 'string']]]  - [280, 0, 'primary', 'tree', {'unique': true}, [[0, 'unsigned']]]  - [280, 1, 'owner', 'tree', {'unique': false}, [[1, 'unsigned']]]  - [280, 2, 'name', 'tree', {'unique': true}, [[2, 'string']]]  - [281, 0, 'primary', 'tree', {'unique': true}, [[0, 'unsigned']]]  - [281, 1, 'owner', 'tree', {'unique': false}, [[1, 'unsigned']]]  - [281, 2, 'name', 'tree', {'unique': true}, [[2, 'string']]]  - [288, 0, 'primary', 'tree', {'unique': true}, [[0, 'unsigned'], [1, 'unsigned']]]  - [288, 2, 'name', 'tree', {'unique': true}, [[0, 'unsigned'], [2, 'string']]]  - [289, 0, 'primary', 'tree', {'unique': true}, [[0, 'unsigned'], [1, 'unsigned']]]  - [289, 2, 'name', 'tree', {'unique': true}, [[0, 'unsigned'], [2, 'string']]]  - [296, 0, 'primary', 'tree', {'unique': true}, [[0, 'unsigned']]]  - [296, 1, 'owner', 'tree', {'unique': false}, [[1, 'unsigned']]]  - [296, 2, 'name', 'tree', {'unique': true}, [[2, 'string']]]---...
