    Written by Se Hoon Park on 06/30/2017 This is the fifth article in the series of "Become a Java GC Expert". In the first issue Understanding Java Garbage Collection we have learned about the processes for different GC algorithms, about how GC works, what Young and Old Generation is, what you should know about the 5 types of GC in the new JDK 7, and what the performance implications are for each of these GC types.

  2. CUBRID Internal: Storage Management (Disk Manager, File Manager)

    Written by Jaeeun, Kim on 08/11/2021 Introduction Database, just as its name implies, it needs spaces to store data. CUBRID, the open source DBMS that operates for the operating system allocates as much space as needed from the operating system and uses it efficiently as needed. In this article, we will talk about how CUBRID internally manages the storage to store data in the persistent storage device. Through this article, we hope developers can access the open source database CUBRID more easily. - The content of this article is based on version 10.2.0-7094ba. (However, it seems to be no difference in the latest develop branch, 11.0.0-c83e33. ) CUBRID Storage Management The CUBRID server has multiple modules that operate and manage data complexly and sophisticatedly.

  3. CUBRID License Model

    Written by Charis Chau on 06/08/2020   Why Licenses Matter?   Open source licenses allow software to be freely used, modified, and shared. Choosing a DBMS with suitable licenses could save the development cost of your application or the Total Cost of Ownership (TCO) for your company. Choosing a DBMS without a proper license, you might find yourself situate in a legal grey area!     CUBRID Licenses   Unlike other open source DBMS vendors, CUBRID is solely under open source license instead of having a dual license in both commercial license and open source license. Which means that for you, it is not mandatory to purchase a license or annual subscription; company/organizational users can achieve the saving from Total Cost of Ownership (TCO).   Since CUBRID has been open source DBMS from 2008,...

  4. CUBRID's Development Culture: The Development Process and Improvements Behind

    Written by Hyung-Gyu, Ryoo on 07/16/2021   Foreword Hello, I am Hyung-Gyu Ryoo, I am working in CUBRID as a research engineer in the R&D department. In this post, I would like to introduce the development process of the open source project CUBRID and the efforts we have made to improve the process.   It has been almost two and a half years since I joined CUBRID.  During this period, as many great fellow developers have joined the CUBRID community, the R&D department of CUBRID has grown from one small team to three developments teams along with a QA team.   After I participated in the first major version release (CUBRID 11), I was able to look back to the release process and improve the development process with my fellow developers.     The Development Process of the Open Source Data...

  5. Contributing to Open Source Community/Project

      Written by Charis Chau on 06/23/2020      What is an open source project? To answer this, let us start with a burger! Imagine an open source project is a burger selling in a restaurant. Every day, the chef makes thousands of burgers that have the same quality by following the same recipe from the restaurant. One day, customer A comes to the burger place to try the burger, and he/she loves it! Therefore, customer A decides to ask the chef whether he/she can get the recipe. Here, if the restaurant is open source, they will be happy to share the recipe to customer A, vice versa.     After customer A gets the receipt, he/she decide to make the burger at home by him/herself! However, customer A is a meat lover and does not like onion that much, so he/she decide to change the recipe by taking o...
