Module box
As well as executing Lua chunks or defining your own functions, you can exploit
Tarantool’s storage functionality with the box module and its submodules.
Every submodule contains one or more Lua functions. A few submodules contain members as well as functions. The functions allow data definition (create alter drop), data manipulation (insert delete update upsert select replace), and introspection (inspecting contents of spaces, accessing server configuration).
To catch errors that functions in box submodules may throw, use pcall.
The contents of the box module can be inspected at runtime
with box, with no arguments. The box module contains:
- Submodule box.backup
- Submodule box.cfg
- Submodule box.ctl
- Submodule box.error
- Submodule box.index
- Examples for
box.index - space_object:create_index()
- index_object.unique

- index_object:parts
