What is Rethink DB?
Rethink database is an open-source database with one of the best query languages among databases. The push functionality of RethinkDB is extremely useful when developing a real-time application. RethinkDB supports server-side subqueries and distributed join operations, which eliminate the need for complicated client-side code and multiple network round trips to the database server. Because RethinkDB does not rely on string parsing, the risk of an injection attack is greatly reduced.
RethinkDB has been designed to be simple to use and install. It also has a robust data model and flexible querying capabilities. It has a fantastic admin interface with a web-based dashboard. The built-in data explorer provides online documentation as well as query language recommendations.
What is ReQL?
ReQL, a Rethink query language variant, is a data-driven, abstract, and polymorphic query language. In ReQL, all cluster operations are scriptable. The Rethink database model is a JSON document store with a query language based on JavaScript. Its partitioning method is based on a sharded cluster model and includes replication. A cluster node can be shared with a few mouse clicks. Aside from that, data is JOIN-able on references, can handle BLOBS, and is geospatial and multi-datacenter compatible. High-level data operations are automatically compiled into map-reduce jobs, which is a benefit of distributed architecture.
- Limitations of RethinkDB
If you require full ACID support or strict enforcement, RethinkDB is not a good choice. In such cases, relational databases are preferable. RethinkDB is a good option, but it performs poorly when compared to Cassandra in both single-node and multiple-node configurations. There are no user accounts in RethinkDB, so you must create your own auth and user accounts. Furthermore, there is no hard limit on the number of databases that can be created, but there is a hard limit of 64 shards.
- There are lots of benefits of RethinkDB over Cassandra
CQL, a Cassandra query language, is similar to SQL in many ways, but it has scalability issues due to the lack of JOINS and aggregate functions. Rethink DB supports map-reduce, a technique for performing aggregation tasks on huge data sets distributed across numerous servers. Rethink DB's real-time push design cuts the time and effort necessary to build scalable real-time apps in half.
- RethinkDB works best suited for displaying sports scores on various online displays
RethinkDB is useful in applications that require continuous real-time data updates. Furthermore, it is best suited for displaying sports scores on various online displays, monitoring systems, and fast workflow applications.
