# Limitations¶

## Nebula Graph versions¶

Only Nebula Graph v2.x is supported.

If you are using Nebula Graph v1.x, please use Studio v1.x. For more information, see Studio v1.x User Guide.

## Architecture¶

For now, Docker-based Studio v2.x supports x86_64 architecture only.

On Docker-based Studio v2.x, only CSV files with comma-separated data and without headers can be uploaded, but no limitations are applied to the size and store period for a single file. The maximum data volume depends on the storage capacity of your machine.

## Data backup¶

For now, you can export the queried results in the CSV format on the Console page. No other backup methods are available.

## nGQL statements¶

On the Console page of Docker-based Studio v2.x, all the nGQL syntaxes except these are supported:

• USE <space_name>: You cannot run such a statement on the Console page to choose a graph space. As an alternative, you can click a graph space name in the drop-down list of Current Graph Space.
• You cannot use line breaks (\). As an alternative, you can use the Enter key to split a line.
