Springboot NoSQL Introduction Spring data provides other projects to help you use a wide variety of nosql technologies, including MongoDB, neo4j, Elasticsearch, SOLR, Redis,gemfire, Couchbase and Cassandra. Spring boot provides automatic configuration for Redis, MongoDB, Elasticsearch, SOLR, and GemFire. You can make the most of other projects, but you need to co

factor. Yes, if you jump out of the box, you can get a lower latency effect in the RDBMS-but I'd like to remind you that relational databases are not designed for such tasks. Oracle is trying to solve the problem by acquiring TimesTen, which has been trying to combine the memory database with the RDBMS-but even if the car adds wings and does not become a plane, we can only think of this as a small improvement in some way. On the contrary, we find that many frequent transaction operators sponta

ApacheCassandra is a distributed, scalable, highly available, and fault-tolerant NoSQL database. It was first developed by facebook and then contributed to the Apache Foundation. Cassandra's data model is inspired by GoogleBigtable, and its distributed model is inspired by AmazonDynamo. If you want to learn more about Cassandra's design details, refer to a Facebook paper. This article describes Apache Cassandra is a distributed, scalable, highly avail

Recently, Twitter developed a distributed real-time statistics system, Rainbird. Usage Rainbird can be used for real-time data statistics: 1. count the number of clicks on each page and domain name on the website 2. Internal System Operation Monitoring (count the running status of the monitored server) 3. Record the maximum and minimum values Performance Requirements As a distributed application of large websites, the following performance is required: 1 High Write Performa
