HBASE: Top Features in Storing Big data

In this post explained top features added in HBase to handle the data. The Java implementation of Google's Big Table you can call it as HBASE.  In HBase, the data store as two parts.
hadoop hbase

Row Key : 00001 
Column : (Column Qualifier:Version:Value)

Features of HBASE

  • HBase data stores consist of one or more tables, which are indexed by row keys.
  • Data is stored in rows with columns, and rows can have multiple versions.
  • By default, data versioning for rows is implemented with time stamps.
  • Columns are grouped into column families, which must be defined upfront during table creation. Column families are stored together on disk, which is why HBase is referred to as a column-oriented datastore
New features of HBASE check now

In addition...

HBase is a distributed data store, which leverages a network-attached cluster of low-cost commodity servers to store and persist data.HBase architecture is a little trick to know.

Region Servers...

RegionServers are the software processes (often called daemons) you activate to store and retrieve data in HBase.

The big difference...

  • HABSE handles growing data or big data. HBase automatically scales as you add data to the system. A huge benefit compared to most database management systems, which require manual intervention to scale the overall system beyond a single server. 
  • With HBase, as long as you have in the rack another spare server that's configured, scaling is automatic.

Amazon Web Services Load Balancer Types
Application Load balancer Network Load balancer Classic Load balancers.
Application Load Balancer

Balancing of HTTP and HTTPS traffic and provides advanced request routing targeted at the delivery of modern application architectures, including microservices and containers. 

Operating at the individual request level (Layer 7), Application Load Balancer routes traffic to targets within Amazon Virtual Private Cloud (Amazon VPC) based on the content of the request.

Network Load Balancer
 Network Load Balancer is best suited for load balancing of Transmission Control Protocol (TCP), User Datagram Protocol (UDP), and Transport Layer Security (TLS) traffic where extreme performance is required.

Classic Load BalancerClassic Load Balancer provides basic load balancing across multiple Amazo…

Though Ethereum leads in the real-time applications. The latest Hyperledger version is now ready for production applications. It has now become stable for production applications.
The Hyperledger now backed by IBM. But, it is still an open source. These interview questions help you to read quickly. The below set of interview questions help you like a tutorial on Hyperledger fabric. Hyperledger Fabric Interview Questions1). What are Nodes?
In Hyperledger the communication entities are called Nodes.

2). What are the three different types of Nodes?
- Client Node
- Peer Node
- Order Node
The Client node initiates transactions. The peer node commits the transaction. The order node guarantees the delivery.

3). What is Channel?
A channel in Hyperledger is the subnet of the main blockchain. You c…

JavaScript Vs JSON Top Differences

Image
Today I woke up after my night sleep, and quickly I completed my daily routines. I thought a few minutes to write useful posts to my readers. I decided to write the differences between Javascript and JSON.



JSON Quick InsightsJSON is simply a data-interchange format and, therefore, does not directly require immediate knowledge of the JavaScript language.JSON a subset of the JavaScript language. Since JSON is made from JavaScript.Data exchange can occur between both browser and server and even server to server, for that matter. Of course, these are not the only possible means to exchange JSON, and to leave it at those two would be rather limiting.The file extension is .json.JSON can be structured:A collection of name/value pairs.An ordered list of values.An introduction to JSON read here.
JavaScript Quick InsightsJavaScript is a text-based scripting language, whereby sequences of Unicode characters are strung togetherJavaScript supports two different types of data types.Primitive and non-…
