Solr (6) Cluster and solr ClusterPreface As the number of users increases, the amount of space and concurrency increases, leading to the failure of a solr server. At this time, the solr cluster must be under.Cluster Architecture 　 Indexing and searching tasks are performed by multiple servers. The solution is to split the index data by shard (sharding). Each shard is completed by multiple servers. When an i

HA (High available) High Availability cluster ( two-machine hot standby)1. Understanding: Two servers A and B , when a service, B idle standby, when a service outage, will automatically switch to the B machine to continue to provide services. When the host is back to normal, the data consistency is resolved through the shared storage system by automatically or manually switching to the host as set by the user.2. The software that implements this func

MongoDB cluster technology: replica set sharding, mongodb ClusterA MongoDB replica set is a process of synchronizing data to multiple servers. The replica set provides redundant backup of data and stores data copies on multiple servers, this improves data availability, ensures data security, and allows data recovery from hardware faults and service interruptions.Mongodb replication requires at least two nodes. One of them is the master node, which is

Zookeeper cluster installation and zookeeper cluster Installation Zookeeper is a highly reliable coordination system for large-scale distributed systems. Therefore, we can Zookeeper is a coordination system, and its role object is a distributed system. So why? Does a distributed system need a coordination system? The reason is as follows: Developing a distributed system is often difficult and complex. Th

Turn from: http://bbs.chinaunix.net/thread-3685716-1-1.html Recently, the realization principle of the Timer quartz cluster is studied, and a method of using database lock to realize concurrency control in cluster environment is found. Because the system is now deployed in the cluster environment, the need for concurrent control, this is a good way to implement,

We understand that the growth of data is a problem that we inevitably face, because in the increasingly changing technology, the way we collect data and the upgrading of storage and processing technology, forcing us to face this problem, and in the increasingly hot data mining today, we also need to pay attention to such issues, change is inevitable!We have thought, in the extreme optimization of the situation, a common server, can be mined out infinite potential, and I did do this, with a 20,00
