Go now implements the Flight SQL extensions for Substrait and transaction support. The Java server builder API now offers easier access to the underlying gRPC builder. The JDBC driver for Arrow Flight SQL has had some bugfixes, and has been refactored into a core library (which is not distributed as an uberjar with shaded names) and a driver (which is distributed as an uberjar). This is based on a Fixed-Size List layout as storage array Represent an Array where each slot contains a tensor, with all tensors having the same Thanks for your contributions and participation in the project! Columnar Format NotesĪ first “canonical” extension type has been formalized: arrow.fixed_shape_tensor to Will Jones have joined the Project Management Committee (PMC). Since the 11.0.0 release, Wang Mingming, Mustafa Akur and Ruihang Xia Many other bugfixes and improvements have been made: we refer The release notes below are not exhaustive and only expose selected highlights To learn how to get the libraries for your platform. With 531 commits from 97 distinct contributors. Over 3 months of development work and includes 476 resolved issues We can create a component that uses Array.The Apache Arrow team is pleased to announce the 12.0.0 release. Let's take a look at a simple example using this array of super heroes: const heroes = The Array.map function comes into its own when we need to insert a list of data from an array into a JSX component. This is the foundation of using Array.map to create JSX code that can be used in React components. This example shows how you can take a load of data stored in an array of objects and use map to create an array of HTML. This will return the following array of HTML: If you want to insert a dynamic value into the HTML you can place an expression inside curly braces like so: Hello c each`) Let’s start by looking at how to use JSX to render dynamic data to the page using React. In this article, you’ll learn how JSX helps to make components in React as close to HTML as possible while still allowing you to write some JavaScript. And thanks to the the Array.map method this can be done in a simple and efficient way. One of the most common tasks for React developers is to render a list of data (e.g.
