Datastore FAQ

How to Improve Datastore Upload Times

In some circumstances Datastore uploads will be slower than network bandwidth allows. The known instance of this occuring is when you have files < .5MB in size. One way to get around this is to upload your Datastore as a compressed file and use a Grid on_experiment_start Action. to decompress it. One such example with Runs is below:

# Get Data
curl -o

# Create Datastore
grid datastore create / --name cifar5

# Create Run and unzip that Datastore
git clone
cd grid-tutorials//getting-started
grid run --config config.yml --dependency_file requirements.txt -- --data_dir /tmp/scratch/cifar5

Data is private

Any datastore you upload to Grid can only be accessed by you. Grid does not look at or manipulate your data in anyway.

Data retention

If you delete your account, all datastores you have created will be deleted immediately and permanently.

Public vs private data

When you create a datastore, you certify that you have the rights to that data. Only you have access to your datastore. It's up to you to make sure you have the rights to access that data.

For additional information, please refer to our Terms of Service.

Does Grid charge for Data Storage?

Grid does not charge for storing data. However, there is a limit of 50 datastores (including any/all version of the same datastore name). If you attempt to exceed this limit, you will have to delete other datastores / versions before your create operation will succeed.

Please reach out to use at or on the community Slack if this limit poses challenges for your workflow; we're happy to assist with alternatives or discuss what a more appropriate usage tier would look like for your usage.

Where does Grid mount my Datastore in a Session or Run?

By default Grid mounts datastores to /datastores/<datastore-name>. This can be customized via cli with the --datastore_mount_dir argument.

Is there a way to see what files are in a datastore?

Create an interactive session with the datastore mounted, then you will be able to browse the data including folders and files using JupyterLab or SSH.

How does Grid store/access my data?

Grid will have access to your account data for operational purposes. If we do need access to your account for debugging purposes, we will notify you.
