Reducing the weight of our footer. Restoring the table from backup will not set it's tags, autoscaling policies, stream settings, TTL settings, and CloudWatch Metrics. To run a Scan operation, which is used to fetch a collection of items, use this command:. Single Scan operation can return up to a maximum of 1 MB of data. Results can be narrowed down using a combination of FilterExpression s and ExpressionAttributeValues.

The following command will only return items where lastName attribute equals Doe. If you want to prevent from creating huge and unreadable CLI commands, you can reference json files too:. If you know the table's Key Schema and want to get a particular item by its key or combination of keys when using composite key , you can use GetItem operation:.

Inserting a new record to DynamoDB can be done using put-item operation. You can reference the item that is to be inserted inline:. Keep in mind that if there's an existing item with the same primary key as the new item in the specified table, the new item completely replaces the existing item.

The Query operation finds items based on primary key values. You can query any table or secondary index that has a composite primary key:. If you want to narrow down the query results on a non-index attribute, you can combine it with FilterExpression :. Keep in mind that FilterExpression is applied after the items have already been read; the process of filtering does not reduce consumed read capacity units.

Sorting in DynamoDB can only be made on an attribute that is indexed as a sort key. The result of this request is an object with an Item attribute containing data for a single item. In this case, we returned an object with multiple Items in it this time.

Notice that the params we used in this query contained a KeyConditionExpression that was looking for the artist property of artist to match the value of :artist stored in the ExpressionAttributeValues.

In this case, the value was an object that contains the attribute type descriptor and the value:. If we want to add another condition to our query we can do so with the sort key operators.

We also then need to create the value that we want the sort key to start with in the ExpressionAttributeValues :. Again, we have multiple items returned back to us. In general, DynamoDB table scans are not efficient operations. In this case, our table was small enough to return all the items in the table. However, if we had a larger DynamoDB table or larger items we might hit the limit of data we can get back in a single call. In that case, we would also get back a value for where to continue the scan operation if we were iterating over all the table data.
