The ObjectStore has helper methods to store strings, JSON objects, XML objects, and bytes.

The ObjectStore has helper methods to store strings and bytes.

ObjectStore.Save(stringKey, stringValue);
ObjectStore.SaveJson<T>(jsonKey, jsonValue);
ObjectStore.SaveXml<T>(xmlKey, xmlValue);
ObjectStore.SaveBytes(bytesKey, bytesValue);

self.ObjectStore.Save(string_key, string_value)
self.ObjectStore.SaveBytes(bytes_key, bytes_value)

To store an object that is in a different format, you need to encode it to one of the supported data types. For instance, if you train a machine learning model and it is in binary format, encode it into base 64 before saving it.

The ObjectStore also has helper methods to retrieve the stored objects.

var stringValue = ObjectStore.Read(stringKey);
var jsonValue = ObjectStore.SaveJson<T>(jsonKey);
var xmlValue = ObjectStore.SaveXml<T>(xmlKey);
var bytesValue = ObjectStore.SaveBytes(bytesKey);

string_value = self.ObjectStore.Read(string_key)
bytes_value = self.ObjectStore.ReadBytes(bytes_key)

For complete examples of using the ObjectStore, see Object Store.

All organizations get 50 MB of free storage in the ObjectStore. Paid organizations can subscribe to more storage space. The following table shows the cost of the supported storage sizes:

When you deploy a live algorithm, you can access the data within minutes of modifying the ObjectStore. Ensure your algorithm is able to handle a changing dataset.

The live environment's access to the ObjectStore is much slower than in research and backtesting. Limit the individual objects to less than 50 MB to prevent live trading access issues.

The Resources page shows the total storage used in your organization and the storage used by individual projects so that you can easily manage your storage space. To view the page, log in to the Algorithm Lab and then, in the left navigation bar, click Organization > Resources.

You need storage billing permissions and a paid organization to edit the size of the organization's ObjectStore.

Follow these steps to edit the amount of storage available in your organization's ObjectStore:

1. Log in to the Algorithm Lab.
2. In the left navigation bar, click Organization > Resources.
3. On the Resources page, scroll down to the Storage Resources and then click Add Object Store Capacity.
4. On the Pricing page, select a storage plan.
5. Click Proceed to Checkout.

To free up storage space, delete the key-value pairs in the ObjectStore by calling the Delete method with a key.

ObjectStore.Delete(key);

self.ObjectStore.Delete(key)
