We’ve written a pretty comprehensive blog about migrating to Scylla in general, but not all of those migration strategies apply to a managed cloud solution. So let’s drill down into specifics and step-by-step instructions targeted directly to your Scylla Cloud success.
We recently launched Scylla Cloud, allowing you to get the most out of Scylla while not having to burden yourself with cluster management tasks. In this blog post we will cover the initial onboarding process, including creating an account and spinning up a cluster.
We covered the basics of Elasticsearch and how Scylla is a perfect complement for it in part one of this blog. Today we want to give you specific how-tos on connecting Scylla and Elasticsearch, including use cases and sample code. Use Case #1 If combining a persistent, highly available datastore with full text search engine is a market requirement, then implementing a single, integrated solution is an ultimate goal that requires time and resources. To answer this challenge we describe below a way for users to use best-of-breed solutions that support full text search workloads. We chose Elasticsearch open source together with […]
“And now for our main event! Ladies and gentlemen, in this corner, weighing in at 34% of the cloud infrastructure market, the reigning champion and leader of the public cloud…. Amazon!” Amazon has unparalleled expertise at maximizing scalability and availability for a vast array of customers using a plethora of software products. While Amazon offers software products like DynamoDB, it’s database-as-a-service is only one of their many offerings. “In the other corner is today’s challenger — young, lightning quick and boasting low-level Big Data expertise… ScyllaDB!” Unlike Amazon, our company focuses exclusively on creating the best database for distributed data […]
Full text search is required in many human-facing applications, such as where users need to interact with a datastore to retrieve and insert data based on partial, wildcard information, spell correction and autocompletion. Additional benefits of full text search is the ability to retrieve multiple results sorted by their relevance. Lucene, the common parent to Solr and Elasticsearch The most popular textual search engine in the market is Lucene. It is used by Solr, Elasticsearch, Lucidworks and other text search tools. Lucene is a great search engine. It is extremely fast, stable, and you probably can’t get much better than […]
Benchmarking is no easy task, especially when comparing databases with different “engines” under the hood. You want your benchmark to be fair, to run each database on its optimal setup and hardware, and to keep the comparison as apples-to-apples as possible. (For more on this topic, see our webinar on the “Do’s and Don’ts of Benchmarking Databases.”) We kept this in mind when conducting this Scylla versus Cassandra benchmark, which compares Scylla and Cassandra on AWS EC2, using cassandra-stress as the load generator. Most benchmarks compare different software stacks on the same hardware and try to max out the throughput. […]
KairosDB, a time-series database, provides a simple and reliable tooling to ingest and retrieve chronologically created data, such as sensors’ information or metrics. Scylla provides a large-scale, highly reliable and available backend to store large quantities of time-series data. Together, KairosDB and Scylla provide a highly available time-series solution with an efficiently tailored front-end framework and a backend database with a fast ingestion rate.
A fast in-memory database provides benefits that we all can appreciate such as optimal latency and throughput for workloads. What if you could utilize extremely fast NVMe drives to have similar latency and throughput results? The scope of this blog post is to examine the outcomes of using an in-memory like database combined with NVMe drives to resolve cold-cache and data persistence challenges. In this experiment, various testing scenarios were done with Scylla and Intel® Optane™ SSD DC P4800X drives with a goal of providing a solution with the performance of an in-memory like database without compromises on throughput, latency, […]
In mid-2015, Intel and Micron jointly unveiled a new kind of non-volatile memory storage device named 3D XPoint (pronounced “cross-point”) that is 1000x faster than NAND. Now that 3D XPoint is generally available and has hit the broad market, we can start testing it. 3D XPoint uses electrical resistance and is considered to be bit addressable. It’s also worth mentioning that the endurance is much better with 3D XPoint because the stated wear leveling is 30 full drive writes per day for 5 years. 3D XPoint developers indicate that it is based on changes in resistance of the bulk material. […]
Introduction A highly available time-series solution requires an efficient tailored front-end framework and a backend database with a fast ingestion rate. KairosDB provides a simple and reliable way to ingest and retrieve sensors’ information or metrics, while Scylla provides a highly reliable and performant backend database that scales indefinitely, and can store large quantities of time-series data.
