4.4 (78.0)
4.5 hours
78 students
What you will learn
1Know how to approach optimization
2Use Query Execution Plan
3Know which data types and why are preferred in a database for better performance
4Avoid unnecessary type conversions in SQL queries
5Efficiently use dictionary tables
6Configure Hibernate to see executed database queries
7Avoid reading data which is not needed
8Eliminate n+1 problem in Hibernate
9Understand a trade off when implementing flexible solutions
10Properly implement data paging in Hibernate
11Efficiently count rows and aggregating data
12Update and delete multiple rows with a single request
13Learn index structure and its impact on query performance
14Choose the right index for a query
15Use of multi column indexes
16Learn the process of executing queries by a database
17Take advantage of query parameters binding in Hibernate
18Avoid long transactions
19Restructure queries for better performance
20Use indexes to support sorting rows and joining
21Know when it is better to avoid Hibernate entities and how to use alternatives
Target audiences
1Java developers using Hibernate that want to understand and improve efficiency of the database operations.
2Software programmers that would like to understand database queries performance and tricks to improve them.
3Developers that would like to use Hibernate in a more efficient manner.
Requirements
1At least basic SQL knowledge.
2Java programming experience is necessary. You should know how to use Hibernate at least on the basic level.
3JDK 15 installed. Some IDE to write, compile and run Java web application. During the course I use IntelliJ IDEA but others should work as well.
FAQ
You can view and review the lecture materials indefinitely, like an on-demand channel.
Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don't have an internet connection, some instructors also let their students download course lectures. That's up to the instructor though, so make sure you get on their good side!
Description

Have you ever wondered why database operations in your application are slow? Is it because of the database or Hibernate or both? Is there anything that can be done to improve that? What are those mysterious database indexes? Does using Hibernate leave me no field for performance optimization?


During this course I will teach you performance optimization techniques that will give you a huge advantage in the Java programmers world.

No, you will not have to give up on Hibernate. It is a great tool. I like it too! Most performance issues with it are caused by inefficient usage, not by Hibernate itself. You can still let it do the dirty job for you and have a highly performant application at the same time.


Java developers too often avoid database topics. But some database knowledge can make your life incredibly easier. In this course, I focus on the aspects that will let you make a significant impact on a database performance with the lowest effort.


Let me show you how to take the best from Hibernate using some database knowledge to achieve high speed of database operations.


After this course, you will know how to combine database tricks with Hibernate best practices to build lightning speed software.
