This post is about how Yelp is transitioning from the management of Cassandra clusters in EC2 to orchestrating the same clusters in production on Kubernetes. We will start by discussing the EC2-based deployment we have used for the past few years, followed by an introduction to the Cassandra operator, its responsibilities, the core reconciliation workflow of the operator, and finally, the etcd locking we employ for cross-region coordination.
Cassandra is a distributed wide-column NoSQL datastore and is used at Yelp for both primary and derived data.

Continue reading. The team is central to growing the number of active users on the Yelp platform. We thought it would be a valuable feature for consumers on Yelp and began researching and MySQL does not include a native high-availability solution for the replacement of a primary server, which is a single point of failure. This is a tradeoff of its dedication to ensuring consistency.
Replacing a primary server is sometimes necessary due to planned or unplanned events, like an operating system upgrade, a database crash or hardware failure. This requires pausing data modifications to the database while the server is restarted or replaced and can mean minutes of downtime. Pausing data modifications means Jupyter notebooks are a key tool that powers Yelp data.
It allows us to do ad hoc development interactively and analyze data with visualization support. As a result, we rely on Jupyter to build models, create features, run Spark jobs for big data analysis, etc. Since notebooks play a crucial role in our business processes, it is really important for us to ensure the notebook output is reproducible.
At Yelp we process terabytes of streaming data a day using Apache Flink to power a wide range of applications: ETL pipelines, push notifications, bot filtering, sessionization and more. Sitting at its core, a Kubernetes operator automatically watches over the deployment and the At Yelp, new web pages and app screens are powered by GraphQL for fetching data. This blog post describes the Dream Query — a pattern our feature teams use when refactoring or creating new pages.
Check out our previous blog post to see how we dynamically codegen DataLoaders to implement the server layer! You may receive a design mock that looks like this At Yelp, usage of Prometheus, the open-source monitoring system and time series database, is blossoming.
Yelp is initially focusing on onboarding infrastructure services to be monitored via Prometheus, one such service being Apache Kafka. This blogpost discusses some of the performance issues we initially encountered while monitoring Kafka with Prometheus, and how we solved them by contributing back to the Prometheus community. By default, Kafka exposes a lot of metrics that can be collected, most of which To connect our consumers with great local businesses, we make millions of recommendations every day for a variety of tasks like: Finding you immediate quotes for a plumber to fix your leaky sink Helping you discover which restaurants are open for delivery right now Identifying the most popular dishes for you to try at those restaurants Inferring possible service offerings so business owners can confidently and accurately represent their business on Yelp In the early days of Yelp circaengineers painstakingly designed heuristic rules to power recommendations like these, but Engineering Blog.

This can be even more frustrating if you, as an entrepreneur, are trying to decide where to focus your limited time, money, and energy to help give your business an edge. Making adoption of social media strategies even more difficult is the fact that this field changes so rapidly. Many of the negative reactions to social media are usually based on an understanding of social media that is limited to snarky Tweets, sharing funny cat videos, and using different filters on Snapchat.
This understanding, however, provides only an incomplete view of what social media can do for you and your business. As I am sure you have seen, however, there are many different types of social media you could use for your business.
It is also important to recognize that while most social media tools are free to use, there are certain products and services that provide a base level of services for free, but charge for more sophisticated services. Fortunately there are some common sense, and budget friendly, things you can do to increase the impact of your social media bucks. For example, if you own a bakery, work in retail, or own a floral business on the side, Pinterest might be the best way to showcase your business.
Focusing on showcasing your business in the best possible light always makes sense, and is no different for social media utilization. Both platforms, especially Facebook, have incredibly large platforms that can boost the reach of your business without costing you an arm and a leg. After you have selected your social media platform of choice, it is important to put together a plan (even a simple plan) on how often you will update, post, or otherwise engage on social media.
Chambers of commerce, small business development centers, and other local resources are just a few of the groups that you should be sure to engage with, and they are always happy to hear from interested parties. Especially for social media, where content is posted and shared on a minute-by-minute basis, it is even easier to adapt your approach to your customers and professional associations.
Social media is a potentially great tool, should be used to help build and expand your business, and can be implemented without breaking the bank. That said, it is impossible to overlook the benefits of building a social media strategy, engaging with customers, and expanding the reach of your business in an increasingly digital environment. Approaching social media from a business perspective, setting up a plan, and selecting the right strategy for your business can set your business up for an effective social media campaign.

The opinions expressed here by Inc. A great thing, especially for Millennials and other entrepreneurs focused on the bottom line, is that the vast majority of social media tools are free to use.
Another wrinkle that can complicate your efforts to get the most for your social media dollars is that many small businesses do not put together a social media strategy that works for business. These suggestions and ideas are certainly not meant to be exhaustive, but should give an idea of how to get the most out of social for your business, and to do so in a way that is also friendly to your bottom line. Social media encompasses a variety of options, not all of which are going to be equally as helpful for your business.Bet Me is the winner of a 2005 RITA Award.

But when Cole Springer goes to Vegas at the behest of Jesse's father, he finds Jesse very much alive.
Unless Springer can figure out what's going on--he won't be alive for very long. Jesse believes that whoever killed his "double" was really trying to kill him, only he doesn't know why--or who was killed in his place. The Vegas strip is full of murder, robberies and red-hot former flames in this fast-paced tale.
