1, Cassandra IntroductionApache Cassandra is a set of open source distributed key-value storage systems. It was originally developed by Facebook to store particularly large data. Cassandra is not a database, it is a mixed non-relational database, similar to Google's BigTable. This article mainly from the following five aspects to introduce CASSANDRA:CASSANDRA dat

Kafka in versions prior to 0.8, the high availablity mechanism was not provided, and once one or more broker outages, all partition on the outage were unable to continue serving. If the broker can never recover, or a disk fails, the data on it will be lost. One of Kafka's design goals is to provide data persistence, and for distributed systems, especially when the cluster scale rises to a certain extent, the likelihood of one or more machines going do
