Couchbase Online Training Course Content
Overview of Couchbase Training:
Let us discuss few concepts of Couchbase Online Training and the remaining in depth concepts are explained during the Couchbase Training.
What is Couchbase?
- In the Couchbase the data is stored in the form of key value format or in the format of JSON object because in this Couchbase we do not use any data schema.
- Developing applications with Couchbase is easy and one of the attribute of Couchbase is memcache D.
- Memcache is a distributed object caching system without changing a line of production code. These existing applications can transition a Couchbase server gaining data replication and durability and ability to add, remove servers with zero application downtime.
- Couchbase provides durable disk-based storage for your data but it also includes a built-in data cache derived from memcache D as data is stored in Couchbase it is automatically cached in RAM.
- In this way the Couchbase delivers predicable low latency access for random reads and writes capacity can be added or removed from a live Couchbase cluster with no application downtime.
- The administrator UI allows any number of servers to be added or removed at once, in this case we have indicated we want to add two servers to the cluster once added rebalance operation is initiated.
“Global Online Trainings provides all types of trainings and among all training institutes Global Online Training is one of the best training institute from India.”
- When the rebalance, operation begins Couchbase determines which of the data in the existing servers should be migrated to the new servers and begins that data migration process.
- Once the data has been transferred to the new servers there made active members of the cluster, the Couchbase client applications are notified of the new cluster configuration.
- And the data is now written to and read from the new locations. Live rebalancing enables continuous operations there is never a need to take an application offline.
- Live rebalancing even permits non-disruptive data base upgrades.
- The Couchbase supports data replication as data is written to Couchbase it is replicated to other servers in the cluster.
- The number of replicas copies is configurable in the case of server failure a manual or automatic fail over operation will eject the failed server and activate replica copies of that data on other servers to ensure data availability during the server outage.
What are the uses of MySQL in Couchbase?
MySQL is a Relational Database Management and it allows the database to store the information. And also MySQL is the free open source and it is the RDBMS that uses SQL. SQL means Structured Query Language and it is the most popular language. And it is used to help for adding, accessing and managing content in a database. And it is processing quickly, good reliability and easy flexibility.
All these concepts help you to gain good knowledge over Couchbase Course also. Couchbase database includes the important data.
“We also provide MySQL Training course at Global Online Trainings by Professional Trainers. It is the basic Online Training for many other Courses.”
A rich set of built in monitoring and management tools support the continuous up time of the Couchbase cluster. About Couchbase course whether one or hundreds of servers. In addition to the built-in administrator UI all metrics and administration functionality are available through a management rest interface supporting.
What are the Couchbase components in Couchbase?
Some of the important components of Couchbase are as follows.
- The cluster will have number of nodes, each and every node will have the Couchbase services.
- These each and every node has v-bucket, that are inside the node.
- V-bucket will be acting like partitions and v-bucket are consider as bucket.
- These buckets are nothing, but database and it stores the actual document.
- Simply V-bucket is nothing but logical storage unit. Each and every V-bucket has partitioned into 1024 partitions.
- The partitions of the V-bucket are distributed in cluster and the details of these v-bucket are maintained in map.
- This map is variable for the all the nodes in the cluster and as well as the client library.
- The basic unit of data storage in Couchbase is a JSON document and each of these JSON document will be assigned with one unique key.
- The user applications will use this key by updating the particular document.
- And this key will be obtained by KETAMA Algorithm to get the Hash value and high availability is achieved through data replication at the V-Bucket level.

Learn about Couchbase Server Architecture in Couchbase Training:
In that Couchbase server architecture block diagram, the first block is the cluster manager, the main function of the cluster manager is to give response to manage all the nodes in cluster. If you want to create a Couchbase cluster, need to select the nodes and we have select the required services.. And this gives a couple of advantages. The main concept of the Couchbase server architecture is to be familiarizing with the exactly that the ability to select the different services and to scale those independently as dataset grows as index in requirement grows as a query requirement.
In automatic sharding of Couchbase data, the cluster and the SDK cooperate to automatically evenly distribute the data across the cluster. It helps to store the Couchbase data documents in the buckets and these buckets are breaks into multiple v-buckets. The v-buckets are nothing but the data nodes in the cluster and the distribution of the data is done efficiently.
“We also provide you the Couchbase Certification after completion of Couchbase Training.”
Exceptional data streaming:
The Database Change Protocol (DCP) was introduced in Couchbase server 3.0 and DCP is the high-performance protocol. Every mutation from the client to network will be send through the DCP. It is used both internally within the cluster for replication to send the updates to the indexer to the full text service and it is also used externally.
Storage Operations in Couchbase can be explained during Couchbase Course:
Whenever the client writes any document in Couchbase, firstly we have to calculate the hash value of the key of that particular document. After calculating the Hash value the client knows the v-bucket of the particular node. So, the document will be directly going to that particular v-bucket node only. And all this document will be stored in replication Queue and this replication queue will replicate the document to another node or else data server.
Learn about Oracle GlodenGate uses in Couchbase Online Training:
Oracle Golden Gate enable to replace and direction of data between multiple, various platforms across the enterprise at the transaction rank. The modular architecture give flexibility to remove and duplicate ideal data records, transactional changes, and modify to DDL (data definition language) diagonally a selection of topologies.
This may be helpful for the individual to get better understanding about Couchbase Online Training. Oracle GlodenGate Training is provided by top experts at Global Online Trainings. It has many benefits that helps the individuals regarding Couchbase Online Training.
Couchbase VS MongoDB can be discussed in Couchbase Online Course:
- Couchbase is nothing but a data store, MongoDB is also a document store.
- It is the combination of Membase and CouchDB. If you have interruption and any query on any multiple objects the couchbase uses http protocol. So these are called as buckets.
- If you want to query an object, we have created views with different columns in the document and theses are called maps.
- The view has the relevant columns, these views are similar to Sybase. These are maps created before query the couch database.
- These are useful because Couchbase identifies the uncreated index over this map. Couchbase uses map reduce, reduce is nothing but it is to create aggregate functions for reducing views.
- So, this is the difference between MongoDB and Couch database, the MongoDB directly query the data store and also it uses the document store for querying the data.
- The one of the difference between Couchbase and MongoDB are, Couchbase has triggers, so we can create triggers inside the Couchbase, the MongoDB does not have triggers.
- The main advantage of Couchbase is offline data base, so we can install Couchbase in our mobile.
- Couchbase is the dashboard in-built, so it is the free dashboard. The MongoDB is not dashboard in-built, if we have different tools they are not free in MongoDB.
