gemfire vs cassandra

According to the official documentation, the installation of JNA can improve the memory usage performance of Cassandra, and on Linux it does not need to put JVM memory on the swap partition to prevent related performance issues.Cassandra 2.0.9 requires JNA 3.2.7 or more, it is recommended to download the installation directly without Yum.1. Download Jna.jar wget Https://maven.java.net/content/repositories/releases/net/java/dev/jna/jna/4.1.0/jna-4.1.0.

mention, they found that in the TC insert 160 million 2-20KB data, write performance began to drop dramatically. It seems that when the amount of data on the billion, TC performance began to decline significantly, from the TC author's own Mixi data, at least thousands the amount of data has not encountered such a significant write performance bottlenecks. Flare, which is an improvement on TC and TT, mainly supports scalability. MongodbTo meet the mass storage requirements, MONGO mainly solve t

Many cache libraries have been implemented in the Java community, with

In this process, you do not need to modify any database schema and application code.At the same time,Voltdb not only supports table partitioning, but also supports table replication. For large tables, you can improve performance by partitioning them. For small tables that are frequently read, you can reduce joinsby copying them.This is similar to the concept of mi

high availability require the framework to solve itself, so to achieve a complete, highly available framework, the complexity is still very high. In addition, the framwork mechanism is suitable for distributed systems that require task distribution and scheduling, such as Hadoop,jenkins.

memory resource pool consisting of up to dozens of terabytes of data can be loaded into the memory for memory computing. The computing process itself does not need to read or write data to the disk, but regularly writes data to the disk in synchronous or asynchronous mode. GemFire stores multiple copies of data in a distributed cluster. If one machine fails and other machines have backup data, you do not have to worry about data loss and have disk da

At the same time, VoltDB not only supports Table Partitioning, but also supports table replication. For large tables, you can use partitions to improve performance. For small tables that are frequently read, you can use replication to reduce join. This is similar to the concept of mirrored region and partitioned region in the dis
