This book is a collection of developer code recipes and best practices for persisting data
using Spring particularly Spring Boot. The book is structured around practical recipes where
each recipe discusses a performance case or performance-related case and almost every recipe
has one or more applications. Mainly when we try to accomplish something (e.g. read some data
from the database) there are several approaches to do it and in order to choose the best way
you have to know the implied trades-off from a performance perspective. You'll see that in the
end all these penalties slow down the application. Besides presenting the arguments that favor
a certain choice the application is written in Spring Boot style which is quite different than
plain Hibernate. Persistence is an important set of techniques and technologies for accessing
and using data and this book demonstrates that data is mobile regardless of specific
applications and contexts. In Java development persistence is a key factor in enterprise
ecommerce cloud and other transaction-oriented applications. After reading and using this book
you'll have the fundamentals to apply these persistence solutions into your own
mission-critical enterprise Java applications that you build using Spring. What You Will Learn
Shape *-to-many associations for best performances Effectively exploit Spring Projections (DTO)
Learn best practices for batching inserts updates and deletes Effectively fetch parent and
association in a single SELECT Learn how to inspect Persistent Context content Dissect
pagination techniques (offset and keyset) Handle queries locking schemas Hibernate types
and more Who This Book Is For Any Spring and Spring Boot developer that wants to squeeze the
persistencelayer performances.
