Scylla vs cassandra

Cassandra and Scylla are two popular NoSQL databases that are widely used for handling large amounts of data.

With ScyllaDB you will achieve higher performance at scale using dramatically fewer nodes, with far less administration, and lower infrastructure costs. You can even switch from Cassandra to ScyllaDB without interruption and commonly with no code changes. ScyllaDB is available as a fully managed service, an enterprise offering, and open source. ScyllaDB was built for performance at scale, delivering lower latency and and higher throughput through its close-to-the-metal design. Read Blog. They also eliminated unpredictable latencies. Fanatics replaced 55 nodes of Cassandra with just 6 nodes of ScyllaDB.

Home Compare ScyllaDB vs. Apache Cassandra. ScyllaDB offers a similar architecture, data format, and query language as Cassandra, but without Java and its expensive GC pauses. You can improve performance at scale with fewer nodes, reduced administration, and lower infrastructure cost. Switching from Cassandra to ScyllaDB is seamless, requiring minimal code modifications. ScyllaDB was built for performance at scale, delivering lower latency and higher throughput via its close-to-the-metal design. ScyllaDB requires fewer nodes to deliver better performance than Cassandra, resulting in significant cost savings and greater ROI. Unlike Cassandra, ScyllaDB scales linearly as you add more nodes, thanks to its shared-nothing asynchronous architecture. Keep your latencies predictable and low, even during maintenance operations such as node replacements, repairs, and topology changes. Cassandra needs a lot of tuning and upkeep. ScyllaDB offers unique features like workload prioritization, which lets you co-locate workloads under a single cluster without compromising performance. G2 rates products and sellers based on reviews gathered from our user community, as well as data aggregated from online sources and social networks. Read More. Watch Video.

But the results speak for themselves. On the other hand, Scylla is based on Cassandra's distributed design and provides a column-family data model, which is similar to Cassandra's, but with additional optimizations for performance.

Cassandra is a poster child of the NoSQL world. Originally an open source project sprung out of Facebook, it has been adopted by the Apache Foundation and backed by an enterprise, DataStax, that also offers DataStax Enterprise based on Cassandra. Cassandra is among the top 10 database solutions according to DB-Engines. That is precisely why it now has a potentially dangerous rival in ScyllaDB. The goal is to be a drop-in replacement for Cassandra, and when we're talking about database 8 in the world, that's kind of a big deal. Dor Laor and Avi Kivity did not set out with this grandiose plan back in

Cassandra is already one of the most highly available NoSQL databases, although its maximum latency under load can run on the high side, because the Java VM needs to garbage collect global memory GC and Cassandra needs to compact its SSTables, both at what are often inopportune times. People try to get around the inconsistent latency problem by combining Cassandra with Memcached or Redis. Finally, introduce a shard-per-core architecture and auto-tuning. Scylla has additional capabilities beyond Cassandra: materialized views, global and local secondary indexes, workload prioritization, and a DynamoDB-compatible API. Scylla also lacks a few capabilities available in DataStax Enterprise , the commercial version of Cassandra, such as the integrated graph database DSE Graph. Scylla boasts single-digit millisecond p99 latencies and millions of operations per second per node. Those two characteristics translate to needing fewer nodes by a significant factor than Cassandra. Scylla adopted most of its scale-out architecture from Cassandra.

First, different implementation language. How is this possible? One of ScyllaDB's benchmarks, in which it is shown to outperform Cassandra. While they share similarities, there are key differences between the two that make them suitable for different use cases. What is Cassandra? The important point is that it accomplishes this at a fraction of the cost of a modern NoSQL database. In our case, these algorithms include the writing and reading data procedures for each database: Scylla and Cassandra. Forum Donate. ScyllaDB promises something simple, alluring, and hard to believe: keep your codebase, replace Cassandra with ScyllaDB, get up to 10 times boost in performance. The problem is that threads require a context switch, which is slow. This is how we got started.

Close-to-the-metal architecture handles millions of OPS with predictable single-digit millisecond latencies. Our blog keeps you up to date with recent news about the ScyllaDB NoSQL database and related technologies, success stories and developer how-tos. This is part two of a two-part blog series on the relative performance of the recently released Apache Cassandra 4.

The Apache Hadoop software library is a framework that allows for the distributed processing of large data sets across clusters of computers using simple programming models. ScyllaDB, instead of relying on page cache, allocates most of its memory to row-cache. We showed up last, but based on Avi's revolutionary design KVM now dominates. It was a combination of market and technical reasons that made Cloudius target Cassandra. Ironically, Cassandra was an Oracle nobody would listen to. How is this possible? We decided to migrate our PostgreSQL -based database systems to a custom implementation of Cassandra. It can distribute data across multiple nodes in a cluster, allowing for horizontal scalability. However, Scylla's community is growing rapidly, and it benefits from Cassandra's vast ecosystem and community knowledge. High availability and scalability are supported out of the box.
