The BatchGetItem operation returns the attributes of one or more items from one or more tables. You identify requested items by primary key. A single operation can retrieve up to 16 MB of data, which can contain as many as items. BatchGetItem returns a partial result if the response size limit is exceeded, the table's provisioned throughput is exceeded, or an internal processing failure occurs.

If a partial result is returned, the operation returns a value for UnprocessedKeys. You can use this value to retry the operation starting with the next item to get. For example, if you ask to retrieve items, but each individual item is KB in size, the system returns 52 items so as not to exceed the 16 MB limit. It also returns an appropriate UnprocessedKeys value so you can get the next page of results.

If desired, your application can include its own logic to assemble the pages of results into one dataset.

If none of the items can be processed due to insufficient provisioned throughput on all of the tables in the request, then BatchGetItem returns a ProvisionedThroughputExceededException. If at least one of the items is successfully processed, then BatchGetItem completes successfully, while returning the keys of the unread items in UnprocessedKeys.

If DynamoDB returns any unprocessed items, you should retry the batch operation on those items. However, we strongly recommend that you use an exponential backoff algorithm. If you retry the batch operation immediately, the underlying read or write requests can still fail due to throttling on the individual tables.

If you delay the batch operation using exponential backoff, the individual requests in the batch are much more likely to succeed. By default, BatchGetItem performs eventually consistent reads on every table in the request.

If you want strongly consistent reads instead, you can set ConsistentRead to true for any or all tables. In order to minimize response latency, BatchGetItem retrieves items in parallel.

When designing your application, keep in mind that DynamoDB does not return items in any particular order. To help parse the response by item, include the primary key values for the items in your request in the ProjectionExpression parameter. If a requested item does not exist, it is not returned in the result.

Requests for nonexistent items consume the minimum read capacity units according to the type of read. A map of one or more table names and, for each table, a map that describes one or more items to retrieve from that table. Each table name can be used only once per BatchGetItem request. Use the character in an expression to dereference an attribute name. For example, consider the following attribute name:. The name of this attribute conflicts with a reserved word, so it cannot be used directly in an expression.

To work around this, you could specify the following for ExpressionAttributeNames :. Tokens that begin with the : character are expression attribute valueswhich are placeholders for the actual value at runtime. For each primary key, you must provide all of the key attributes. For example, with a simple primary key, you only need to provide the partition key. For a composite primary key, you must provide both the partition key and the sort key.

The primary key attribute values that define the items and the attributes associated with the items.I tried with filter but no luck. I like this code because I was unable to find any other code example of using boto3 and printing the specific tag values.

However, looks like this code would not run properly if the running EC2s have multiple tag names that have "Name" in the tag names. For example, the running instances has a tag name "Name" and value "web1" and has another tag name "Cluster Name" and value "US-West". I have not tested it yet, but I will circle back after I test it. As ikekim said this will not work properly if instance.

However, if any part uploads are currently in progress, those part uploads might or might not succeed. As a result, it might be necessary to abort a given multipart upload multiple times in order to completely free all storage consumed by all parts. To verify that all parts have been removed, so you don't get charged for the part storage, you should call the ListParts operation and ensure that the parts list is empty.

The following operations are related to AbortMultipartUpload :. When using this API with an access point, you must direct requests to the access point hostname. You first initiate the multipart upload and then upload all parts using the UploadPart operation.

After successfully uploading all relevant parts of an upload, you call this operation to complete the upload. Upon receiving this request, Amazon S3 concatenates all the parts in ascending order by part number to create a new object. In the Complete Multipart Upload request, you must provide the parts list. You must ensure that the parts list is complete. This operation concatenates the parts that you provide in the list. For each part in the list, you must provide the part number and the ETag value, returned after that part was uploaded.

Processing of a Complete Multipart Upload request could take several minutes to complete. While processing is in progress, Amazon S3 periodically sends white space characters to keep the connection from timing out.

Because a request could fail after the initial OK response has been sent, it is important that you check the response body to determine whether the request succeeded.

Note that if CompleteMultipartUpload fails, applications should be prepared to retry the failed requests. The following operations are related to DeleteBucketMetricsConfiguration :. If the object expiration is configured, this will contain the expiration date expiry-date and rule ID rule-id.
