The first idea for a mainframe was developed by a Harvard researcher who took the concept to IBM in the 1930s. After a decade or so of development, the 5 ton machine – that filled an entire room and would cost around $3M today to build – was ready to use in 1943. Industries such as banking, retail, insurance, utilities, healthcare, and government still rely on their mainframes to handle their most sensitive, large-scale transactional data. Mainframes excel when it comes to security and reliability which is why many organizations trust them with their mission-critical workloads.

Companies move to the cloud to take advantage of a wide variety of benefits, but building your infrastructure on a public cloud also comes with risks. Chief among them is vendor lock-in and the fear of being at a single cloud provider’s mercy, locked in behind what would be the months or years of work necessary to switch to a different cloud. But operating across multiple clouds at the same time is technically difficult and often prohibitively expensive. Many companies have embraced a different way of mitigating the lock-in risk: cloud portability.

When working with a database, it’s common practice to use some kind of id field to provide a unique identifier for each row in a table. Imagine, for example, a customers table. We wouldn’t want to use fields such as name or address as unique identifiers because it’s possible more than one customer could have the same name, or share the same address, or in some cases even both! Instead, it’s a good idea to assign each row some kind of truly unique identifier. One option we have is to use a UUID.

In an ideal world, all workloads are perfect and never face performance issues. In the real world, that’s hard to achieve. Your workload might not always follow best practices, or it could contain problematic queries that cause trouble.

We are thrilled to announce that CockroachDB dedicated, the fully managed single-tenant version of CockroachDB, is now HIPAA-ready and can be used to safely store protected health information (PHI). Any organization working in healthcare needs to comply with HIPAA requirements to protect sensitive patient data, regardless of whether they’re a “covered entity” (hospital, health insurance plan, pharmacy, etc.) or “business associate” (an organization that works with a covered entity).

CockroachDB has lots of customers who’ve switched from Oracle and other legacy SQL databases, saving both money and time. Generally speaking, though, we can’t share their names or specific details about their internal processes and workloads. So in this article we’ll be doing something a bit different. We wanted to tell the story of what it’s like for a finance company to transition from Oracle to CockroachDB. The names and quotes in this narrative are fictional, but the story itself is real. It comes from the things we’ve heard working with real-world customers in the finance industry – including Fortune 50 banks – who are moving transactional workloads off of Oracle and onto CockroachDB.

It’s 10 o’clock. Do you know where your data is? Chances are, it’s nestled snugly in its database. But chances are that it’s also less secure than you might think. Even in sophisticated systems with backups and failover plans, data loss is possible. And importantly, it can happen without you realizing it’s even possible – at least, not until it’s too late.

CDC Queries are SQL-like statements that allow you to (1) filter (2) transform (3) and choose the schema of your data stream. Instead of the headaches of sidecar services or downstream tools, filtering and transforming streaming data is now as simple as a SQL query. Here is a quick video tutorial about how to use CDC Queries that accounts for all the new functionality as of the CockroachDB 23.1 release:

We’re giving CockroachDB’s interactive SQL shell a face lift in v23.1! The SQL shell is the interactive read-eval-print loop (REPL) bundled inside CockroachDB under the command cockroach sql. It is also available as the standalone and more modestly sized cockroach-sql downloadable program, as well as our development tool cockroach demo.
