[Elasticsearch] Distributed File Storage This article is translated from the distributed document store chapter in the Elasticsearch official guide.Distributed Document Storage In the previous chapter, we have been introducing index data and methods for getting data. However, we omit many technical details about how data is Distributed and Fetched in the cluster.

Elasticsearch Config folder has two configuration files: Elasticsearch.yml and Logging.yml, the first is the basic profile of ES, the second is the log configuration file, ES is also used log4j to record the log, so logging.yml Settings are set according to the normal log4j configuration file. The following is the main explanation of the Elasticsearch.yml this file can be configured things.Cluster.name:elasticsearchConfigure the ES

Using Elasticsearch to mention the Curl tool,Curl is an open source file Transfer tool that works with URL syntax in the command line mode. Website address:https://curl.haxx.se/Because Elasticsearch provides a standard HTTP interface, we can use curl to easily access the Elasticsearch.Some of the following collections use the Curl command to manipulate Elasticsearch.First: _cat seriesThe _cat series provide

After elasticsearch is installed, We need to configure a series of elasticsearch configurations as follows: Cluster. Name: rmscloud Cluster name Node. Name: "rcnode21" Node name Node. Tag: "tag21" Node label Node. Data: True Whether the node stores data Index. number_of_shards: 5 Number of index shards Index. num

This Learning note comes from the ES official website's Guidance document: ES JAVA API Client client is a class that enables various operations on the ES cluster: Index, GET, Delete, Search , as well as management tasks for ES clusters. Client constructs need to be based on the transportclient transportclient transportclient can remotely connect ES clusters through a transmission module, but it is not really connected to the

When we use Logstash to collect logs, we usually use the dynamic Index template that comes with logstash, although we can push our log data to the Elasticsearch index cluster without any custom action, but when we query, we find that The default index template often puts us in a field that does not need a word breaker, so that our more important aggregated statistics are inaccurate:For example, if there are

, you can do directed storage, directed search." ”Suppose you have an index of 100 shards. What happens when a request is executed on the cluster?1. The request for this search is sent to a node2. The node receiving the request broadcasts the query to each shard of the index (either the primary Shard or the replication shard)3. Each shard executes this search query and returns the result4. Results are merged, sorted, and returned to the user on the ch

In the previous article, we already know how to store the data in the index and how to retrieve it. But we're masking the technical details of the specific implementation of data storage into the cluster and getting data from the cluster (but we glossed over many technical details surrounding how the data is distributed and Fetched from the cluster). 1.

single shard with a single node. Try indexing 100 document first, then 200, then 400, and so on. Each time the benchmark is run, the number of document is doubled accordingly. The highest index speed is obtained, which is the best number of bulk bulk requests. Of course, volume requests are not the more document the better. If concurrent requests occur concurrently, too large bulk requests can make the cluster memory pressure larger, so it is recomme

]:[port (9200)]/[index]/[type]/[id]? [option], whereas indexes in Lucene correspond more to the concept of shards in ES. Back to elasticsearch,es the architecture follows the design concept with the following characteristics: 1. Reasonable default configuration: simply modify the Yaml configuration file in the node and you can configure it quickly. This is similar to the simplification of the configuration in Spring4. 2.

Unable to get information about pods and container Unable to get run information for other nodes in the cluster It is therefore still necessary to look for platform-level architecture scenarios.
