What is custom duty/charge?

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order?

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges?

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.

When designing data-intensive systems, a common problem is the sheer volume of data being processed. One way to solve this problem is sharding. This book describes the Apache ShardingSphere library that implements this method.This library implements architectural and software tools for organizing a segmented data warehouse that includes various DBMS. The library provides a set of different features, ranging from setting up various sharding schemes to a separate agent for managing shards. This library is a good tool for designing, developing and using complex sharded databases.As part of my projects, I used this library to work with sharded PostgreSQL partitioned by database. What was my surprise when, after a simple setup, I was able to work with several databases as a whole! Support for the PostgreSQL dialect is still far from perfect, but on the way to it.I strongly encourage you to try the library through the study of this book.

A Definitive Guide to Apache ShardingSphere’ helped me to deep-dive and understand the capabilities of ShardingSphere and the more flexible and cost-effective solutions they provide.I got to know about the Database Plus driving development concept used in the software’s architecture.This book is a perfect fit for someone wanting to know more about the potential use cases of ShardingSphere that are necessary for a distributed database as it provides explanatory details of how to install and use ShardingSphere-Proxy,as MySQL and PostgreSQL servers.how ShardingSphere-JDBC connects to databases, its third-party database connection pool, and how to successfully install it,how to use its performance testing system and many more such features.I found the example code-blocks and the yaml configuration demonstrations really helpful.The best feature that I loved about the book are the example projects it provides.

This a very well written book and provides great insight into distributed databases. As eventdrivenarchitecture and eventstreaming have grown with the usage of design patterns like CQRS and EventSouring; thus, having the ability to store a system of record using a domain model is very important. In the past, I have accomplished this by using EventStore or Marten in a NoSQL method. The events are persisted in an event store that acts as the authoritative data source about the current state of the data. The event store typically publishes these events so that consumers can be notified and can handle them if needed.Apache ShardingSphere provides the same benefits by creating a distributed database through the usage of PostgresSQl and MySQL. It is easy to scale the database horizontally both in compute and storage. Further Apache SharingSphere provides migration capabilities to help migrate the data from other data sources, while simultaneously performing data sharding. This leads to the ability to create a datamesh architecture for advanced analytics.

The book "A Definitive Guide to Apache ShardingSphere" proved to be very helpful for me because after reading it I was able to learn more about ShardingSphere's capabilities and the more adaptable and affordable solutions they offer thanks to this book. There is a complete detailing done in the book about environment setup for ShardingSphere-Proxy and ShardingSphere-JDBC. After the introduction, it also discusses about the architecture and configuration of Apache ShardingSphere. The best part is that it gives a brief on the scenario test cases and the performance giving plugins platform introduction and SPI, then finally giving the best use cases and future cases to practical real-world examples.This book is for all the ShardingSphere as well as Database enthusiasts out there.

Great read for people looking to attain in depth knowledge of ShardingSphere. I could individually connect with this book since I had used ShardingSphere to horizontally scale MySQL database. Many SQL DBs inherently don't come with an inbuilt sharding feature. ShardingSphere comes to rescue in such cases by just creating an abstraction layer between the application and the DB. Highly recommended for Devs working in this domain as well as DBAs, or whoever is curious to explore this area.
