Para was designed to be a simple and modular backend framework for object persistence and retrieval. It helps you build applications faster by taking care of the backend. It works on three levels - objects are stored in a NoSQL data store or any old relational database, then automatically indexed by a search engine and finally, cached. Para is also multitenant and has a clean and easy-to-use JSON API.
The name \"pára\" means \"steam\" in Bulgarian. And just like steam is used to power stuff, you can use Para to power your mobile or web application backend.
Why use it? Because it's open source, well documented and tested and it's just easier to use than most frameworks out there.
It's free to get started!
Get it through Maven or as an executable JAR package.

A managed service based on the open source library Para. Adding your own features is a pull request away on GitHub.
We are hosted on Amazon Web Services, inside a private cloud, which allows us to scale up and down quickly.
You can always switch to another hosting service or run Para on your infrastructure. We're cool with that.
Our simple JSON API and client SDKs allow you to easily integrate Para into your code.
Your users can be authenticated with their social accounts and Para will issue a JSON Web Token (JWT). LDAP and Active Directory are also supported. This combined with powerful resource permissions for each user, gives you great flexibility and security.
All your objects are indexed automatically by Elasticsearch - a robust and scalable search engine. Para supports many types of queries like basic field queries, wildcard, geo point, and \"more-like-this\" queries.
The API is simple and secure. Using basic HTTP methods you can create, read, update and delete objects. It also supports pagination and field limiting. All API calls are signed using the latest AWS signature v4 algorithm, used by Amazon.
Your objects are cached when they are created or updated. Caching allows for faster read times and decreases the load on the database. This works great for \"hot\" objects that don't change very often.
Para stores data in several regions of the AWS cloud and is powered by DynamoDB - a scalable, fault tolerant database with very low latency. Your data is stored in globally replicated tables, encrypted, on Solid State Drives (SSDs).
Premium plans feature an easy-to-use backup and restore control panel which enables you to import and export data from Para. Simply download the JSON data archive and restore it when needed.
per app, monthly
\nThe prices don't include European Union VAT (not applicable to customers outside the EU).
Billing is on a monthly basis. Annual billing is also available - pay 10 months and get 2 months free. Additional storage and app credits can be purchased at any time.

Welcome to the Awesome Accord repository! This guide provides resources and examples for implementing ACID transactions in Apache Cassandra. Learn how to leverage distributed transactions for building reliable applications.
Accord is in active development and still a feature branch in the Apasche Cassandra® Repo. You will find bug. What we ask is that you help with a contribution of a bug report.
You can use the Github discussions bug report forum for this or use the Planet Cassandra Discord channel for accord listed below. A bug report should have the folowing:
If you have suggestions about syntax or improving the overall developer expirience, we want to hear about that to! Add it as a suggestion or feature request using Github discussions or let us know in the Planet Cassandra Discord.
Now, on to the fun!

Cloud native is now mainstream in infrastructure. In a recent CNCF survey, 84% of organizations used or evaluated Kubernetes (and that figure has been growing steadily). Every cloud provider has a managed Kubernetes environment, and on-prem organizations are creating their own self-managed clouds. DataStax has been on the leading edge of the Data on Kubernetes movement since the release of K8ssandra and the K8ssandra operator nearly four years ago. And probably one of the strongest endorsements of this trend in technology, our Apache Cassandra® as a Service, DataStax Astra DB, runs completely on Kubernetes and cloud native technology. We successfully deploy thousands of clusters a week reliably and quickly. As you’ll see, we aren’t just sitting on all that knowledge.
With over twelve years of bringing Cassandra to the enterprise and some of the best partnerships in the industry, we’ve developed a wealth of experience working with your needs. We listen and respond to your challenges, always keeping your needs at the forefront of our product development. A common request: you want to be more cloud native when it comes to self-managing your data infrastructure. Astra DB is a popular offering for those enterprises migrating to a managed Cassandra in the cloud. Not all of you can take advantage of this service, but you’ve been asking for something similar as a self-managed offering.
DataStax Enterprise (DSE) is close, but we can’t just put it in a container and call it cloud native. So we took your input, dug deep into our experience with DataStax Astra and K8ssandra, and released our new self-managed option, Hyper-Converged Database (HCD)—a green-field approach to delivering data infrastructure for the future. HCD includes Mission Control to manage the deployment and ongoing operations while providing integration with existing cloud native Kubernetes installations. The initial release will support Cassandra workloads with notable enhancements such as the Data API, which eliminates data modeling with Cassandra and has been adopted by developers in Astra. For generative AI workloads, we have an add-on for the state-of-the-art vector search engine, JVector.
The first question you might ask is how this differs from DSE. DSE 6.9 was released today and is still a product line, but it is available in the classic download format of tar, package, or Docker image. DSE remains an option for teams using advanced workloads such as Solr, Spark, or Graph. If you’re an OpsCenter user, it's available as a download for an easy in-place upgrade. Mission Control can manage DSE and HCD clusters if you want a single control plane for all your Cassandra clusters. These systems complement each other based on your use case and deployment profile.
The real difference is what this means for the future of your cloud native infrastructure. To be truly \"cloud native,\" your applications should exhibit properties like scalability, elasticity, self-healing, and observability. HCD encapsulates our expertise in delivering these properties, enhancing your experience as you grow and strive for efficiency. We’re committed to delivering a future-proof solution that will keep you ahead of the curve. Experienced users will no doubt notice that we’re resetting some things to avoid technical debt, and that’s true. The result is that you’ll have an enterprise data option that will move fast and have a much more interesting roadmap based on the agility we’ll now have. Roadmap items that we’ve already announced include the addition of streaming and OpenSearch fully integrated and optimized for developer experience.
What we’re releasing today is version 1.0 of HCD, which covers core Cassandra workloads and includes the Data API; you can add vector search for next-generation application needs. If you want to build cloud native GenAI applications, this is a great place to start. You also get Mission Control to help deploy and administer your infrastructure in one or more datacenters. Backup, restore, repairs, migrations, security—all much easier than anything you’ve ever done before with Cassandra clusters. We can say that confidently because we do this every day on Astra DB, and now you can in your own self-managed systems.
To get started, we have some great resources for you. You’ll begin with Mission Control, which enables you to create and maintain an HCD cluster. You can follow the “Getting Started” section in the documentation or view our curated YouTube playlist. Once Mission Control is up and running, deploying your first HCD cluster only takes a few minutes. You’ll be amazed at how easy it is, and congratulations, welcome to the club! This is how our engineers running Astra DB feel every day.
We've also made DataStax Enterprise 6.9 generally available; read about it!
