Is Elasticsearch a time series database?
Elasticsearch is a fantastic tool for storing, searching, and analyzing structured and unstructured data — including free text, system logs, database records, and more. With the right tweaking, you also get a great platform to store your time series metrics from tools like collectd or statsd.
Does Netflix still use Cassandra?
Netflix has been rolling out the Apache Cassandra NoSQL data store for production use over the last six months. As part of our benchmarking we recently decided to run a test designed to validate our tooling and automation scalability as well as the performance characteristics of Cassandra.
Is Cassandra database free?
Apache Cassandra is a free and open-source, distributed, wide column store, NoSQL database management system designed to handle large amounts of data across many commodity servers, providing high availability with no single point of failure.
Why is Cassandra good for time series data?
Cassandra has good support for modelling time series data wherein each row can have dynamic number of columns. … Since Cassandra is highly efficient with writes, this write heavy workload is a good fit for Cassandra.
Is InfluxDB SQL?
InfluxDB is similar to a SQL database, but different in many ways. … Relational databases can handle time series data, but are not optimized for common time series workloads. InfluxDB is designed to store large volumes of time series data and quickly perform real-time analysis on that data.
Is Cassandra a SQL?
For all intents and purposes, CQL is SQL, so in the strictest sense Cassandra is an SQL database. … Under this (mis)interpretation, Cassandra should not be considered an “SQL database” since it is not relational, and does not support ACID properties.
Can Cassandra store unstructured data?
Apache Cassandra is a massively scalable, column family NoSQL database solution that provides users the ability to store large amounts of structured and unstructured data. In the big data landscape, it fits into the structured storage category and is simply an alternative or additional data store option.
What type of database is Cassandra?
Apache Cassandra™ is a distributed NoSQL database that delivers continuous availability, high performance, and linear scalability that successful applications require.
When should you not use Cassandra?
Cassandra is based on a NoSQL database and does not provide ACID and relational data properties. If you have a strong requirement for ACID properties (for example Financial data), Cassandra would not be a fit in that case.
Is Cassandra a relational database?
On a recent project, we decided that, instead of a standard RDBMS, we would use Cassandra. … However, it would be irresponsible to discuss the challenges of using Cassandra after over nine years using relational databases, without a quick word about what Cassandra is. Cassandra is a NoSQL database.

What the heck is time series data?
Simply put: time-series datasets track changes to the overall system as INSERTs, not UPDATEs. … In short, here’s how I like to define time-series data: a collection of values that represents how a system/process/behavior changes over time.
What is Cassandra database good for?
Apache Cassandra is a highly scalable, high-performance distributed database designed to handle large amounts of data across many commodity servers, providing high availability with no single point of failure. It is a type of NoSQL database.
How is data stored in Cassandra?
Logging writes and memtable storage When a write occurs, Cassandra stores the data in a memory structure called memtable, and to provide configurable durability, it also appends writes to the commit log on disk. … The memtable is a write-back cache of data partitions that Cassandra looks up by key.
