Introduction Couchdb is a database that has been sought after by geek in the past two years. The author was a lotus developer. Unlike traditional relational databases, it claims to be a document database. The so-called document database does not mean that it can only store text because it is actually a schemal-less concept. All those who have used relational databases know that each field defined in the data table is defined as a Type: int, Char, date

CouchDB 0.11.0 released the download , the NoSQL database interested friends can go to the official download the latest CouchDB 0.11.0 trial. With the occurrence of "Digg and Reddit joining the NoSQL camp" in the previous period, the author has a simple understanding of the NoSQL database. At the same time, the NoSQL of the Couchdb class also has interest. If you

cbbackupThe tool is a flexible backup command that enables you to back up local data and remote nodes and different combinations of data that involve your cluster:Single node single bucketsAll buckets on a single nodeA single buckets on the entire clusterAll buckets on the entire clusterBackups can copy files directly on a separate node, or they can be saved to a backup location by connecting to a remote cluster and then through the data stream. Backups can be run on a running node or on a clus

Couchbase is an open-source, distributed, document-oriented (document-oriented) NoSQL database with built-in Memcached services.

Looking back at one of my previous blogs, in Fabric 1.0, we have 3 types of data stores, one based on the file system Blockchain data, which is like Bitcoin, and bitcoin is also stored in file form. The blockchain in Fabric1.0 stores the transaction order read-write set. What exactly is read and write set? Write what? In fact, our state Database, also known as the World State, stores the business data we operate in Chaincode in the form of key-value pairs. There is also a database of historical

. Without a single point of failure, no single point will cause data to be inaccessible. Read and write loads can be distributed evenly across different nodes of the system. Support for asynchronous persistence facilitates rapid recovery and can even be used directly as a key/value database. Often when communicating with friends in the industry, you will mention using the key segmentation method to do capacity expansion and load balancing. However, there are many problems with static key segment

Couchdb, as part of the nosql trend, is easy to compare with the database labeled with buzzwords. Key-value stores, tuple stores, bigtable clones, document store, graph database, and other labels are attached to each category. These classification labels sometimes help programmers outline the technical properties of the latter segment, but in many cases, the programmer's preference may be wrong and biased. We can say that these new technologies all w
