Amazon Athena provides assistance for User Defined Functions (UDF)

Amazon Athena is an interactive query service which makes simple to study data straight in Amazon S3 with the help of standard SQL. You do not need to handle any infrastructure as Amazon Athena is serverless. Athena is simple to utilize. Simply point to your data in Amazon S3, specify the schema, and begin querying using standard SQL to execute ad-hoc queries and you will get results within seconds with few clicks in AWS management console. There is no necessity for complex ETL jobs to make your data for analysis with Amazon Athena. This makes it simple to SQL expertise to faster explore large-scale datasets. Now Amazon Athena offers new feature i.e. user-defined functions (UDFs), a feature which allows users to write custom scalar functions and call them in SQL queries. While Amazon Athena presents built-in functions, UDFs allow users to execute custom processing like compressing and decompressing data, redacting sensitive data, or applying customized decryption. Using Athena Query Federation SDK users can write their UDFs in Java. When a UDF is used in a SQL query submitted to Athena, it is called and performed on AWS Lambda. UDFs can be utilized in both SELECT and FILTER clauses of a SQL query. Users can call several UDFs in the same query. This new Athena UDF feature is accessible in Preview mode in the us-east-1 (N. Virginia) region. You can follow these steps to start your Preview. To know more on User Define Functions (UDF), read documentation. You can get UDF example implementations here. And to know further how to write your functions with Athena Query Federation SDK, go through this link.

Now Amazon Kinesis Video Producer SDK Provides Support in C

Amazon Kinesis Video Streams is an entirely controlled AWS service which can utilize to stream live video from devices to the AWS Cloud, or create applications for real-time video processing or batch-oriented video analytics. Also allows you to playback video for live and on-demand viewing, and faster create applications which use benefit of computer vision and video analytics via integration with Amazon Recognition Video, and libraries for ML frameworks such as Apache MxNet, TensorFlow, and OpenCV. The Amazon Kinesis Video Streams Producer libraries are a group of libraries which are segment of the Kinesis Video Streams Producer SDK. Amazon Kinesis Video Streams producer SDKs are free and open software libraries for creating applications which can stream audio and video data straight from an edge device to the AWS cloud for durable storage, playback, and machine learning based processing. Now Amazon Kinesis Video Streams producer SDK is accessible in C. Now developers can pick between C, C++, and Java SDKs to create streaming applications that top fits their edge device platform with this new feature support of producer SDK in C. Linux, MacOS, Windows, and Raspbian platforms can access Producer SDK in C and also further obtainable as a Docker container for deployment. Refer documentation to get more detail information about this feature and region table to get the full list where Amazon Kinesis Video Streams is available.

Now AWS Encryption SDK for C is Accessible

The Encryption SDK is a client-side library which makes it simpler for you to execute best-practice encryption. The Encryption SDK for C is being developed in open source in GitHub. The AWS Encryption SDK for C is created to offer a client-side encryption library for developers who are creating applications in C. Additionally, it works as a base for implementations of the AWS Encryption SDK in higher-level programming languages. Now, the AWS Encryption SDK for C is accessible to encrypt and decrypt your data in C and C++ applications. The AWS Encryption SDK for C is thoroughly well functioning and completely compatible with the Java, Python, and CLI implementations. Keyrings are offered by the AWS Encryption SDK for C that assist you to encrypt your data under different wrapping keys, covering keys in several AWS Regions. At the time of decryption, you can define which of the keys that encrypted the data can be utilized to decrypt it. You can describe every keys, a subset of keys, or one specific key, also any region, a subset of regions, or one specific region. For a complete example, refer examples. Go through the AWS Security blog about How to decrypt ciphertexts in multiple regions with the AWS Encryption SDK in C for more information.

Now DynamoDBMapper Offers Assistance For Amazon DynamoDB Transactional API Calls

The AWS SDK for Java offers a DynamoDBMapper class, permitting you to link your client-side classes to DynamoDB tables. To access DynamoDBMapper, you specify the relationship between items in a DynamoDB table and their related object instances in your code. The DynamoDBMapper class allows you to access your tables, executes different create, read, update and delete (CRUD) operations, and run queries. Now DynamoDBMapper gives assistance to Amazon DynamoDB transactional API calls, allowing developers who utilize DynamoDBMapper to define their code when creation cooperated, all-or-nothing modifies to various items both within and across DynamoDB tables. Now, DynamoDBMapper can be utilized by developers to run transactions. The transactional APIs offer developers atomic, consistent, isolated, and durable (ACID) operations in DynamoDB so that they can retain data accuracy in applications extra simply. Developers can help workflows and business logic which need adding, updating, or deleting multiple items as a single, atomic operation with transactions. This new feature is accessible in every standard AWS Regions where DynamoDB is available. Pricing for transactions is depends on the sizes of the items in the transactions. To download the AWS SDK for Java with the current version of the DynamoDBMapper class, refer AWS SDK for Java.
