For this problem, most people appear in this place:Client client = new TransportClient(settings).addTransportAddress(new InetSocketTransportAddress("172.16.2.13", 9300));?The problem is that a new name was set for cluster when initializing Settings earlier, such as: Settings Settings = Immutablesettings.settingsbuilder (). Put ("Cluster.name", " Tonsonmiao "). Build ();Because if ClusterName is set, the container will look for the IP and port to be set from the cluster name Tonsonmiao when addin

Label:Elasticsearch has a plug-in module called River that can import data from an external data source into a elasticsearch and index it. The river is a singleton pattern on the cluster, it is automatically assigned to a node, and when the node is hung, the river is automatically assigned to another node. Currently supported

do not do too much to explain, you can refer to MySQL client/server Protocol detailed understanding of MySQL Protocol,binlog events and other related knowledge. The related replication functions are implemented in the Go-mysql project.MySQL DumpIf it is a new MySQL, of course we can binlog the way to synchronize data conveniently. But if we want to sync a MySQL that's been running for a while, there might be a problem. Since earlier Binlog files have

Text mode batch update multiple fields The simplest use of an update request is to add new data. The new data is merged into the existing data, and if the same field exists, it is replaced by the new data. For example, we can add tags and views fields for our blog: Post/website/blog/1/_update { "doc": {" tag

The Elasticsearch data is stored on the hard disk. When our access logs are very large, kabana is very slow when drawing graphics. and hard disk space is limited, it is not possible to save all log files. What if we want to get the important data of the site every day, such as the amount of traffic per day, and the way we want to visualize it?First, the specific
