apache in memory database

Project Background: Altibase is a database management system (DBMS) that stores data in different storage media and manages it. It supports both memory databases (MMDB: Main Memory Database) and disk databases (drdb: disk-resident database), to achieve extremely high access

Memory Database In traditional database tables, due to the limitation of the physical structure of disks, the structure of tables and indexes is B-Tree, which makes such indexes very weak in the highly concurrent OLTP environment, although there are many ways to solve such problems, such as optimistic concurrency control, application caching, and distributed. How

) 8-bit DOS application with a 32-bit architecture. Now the pressure is turning to software engineers: When are they going to recompile the application and take advantage of the new data types and memory-addressable capabilities that new hardware offers? In the final analysis, you will run the "Hello World" program as long as it takes to write the program when you run the BASIC in 8086 compared to C + + running on 24-way SMP. However, the

When the SQL Server database engine runs on Microsoft Windows NT or Windows 2000, its default memory management behavior is not to obtain a specific amount of memory, instead, obtain as much memory as possible without generating additional page I/O. Therefore, the database e

Network : Select the appropriate network card, to ensure that networks are not the bottleneck of the system. When evaluating database server performance, the most difficult thing is how to grasp the accuracy of the problem, exactly what factors to consider. Ideally, the following elements should be consider

, it is recommended that you record all the adjustable items that have been modified (obtain a copy of the/etc/tunables/nextboot), and then revert the adjustable items to their default values. After the migration, check the nextboot and make sure nothing is in it. Now, discuss the adjustable items that need to be modified for AIX 6 or 7. Paging space Best practices recommend that you configure multiple paging spaces of the same size on a different, less busy hard drive (Hdisk). All paging spac

SQLite introduction 1. SQLite is an embedded database that implements a large subset of the SQL92 standard. it combines database engines and interfaces in a database, and is famous for storing all data in a single file. I think SQLite functions are between MySQL and PostgreSQL to some extent. however, in terms of performance, SQLite is often 2-3 times faster (or

Detailed description of database paging, memory, and IO latency I wrote an article on AIX optimization a few years ago. now I see it in AIX 7, therefore, it is necessary to review the basic tuning measures that need to be performed on the AIX system. Many of the released technical levels (TL) and some suggestions may change. In this article, I will provide AIX tuning information related to callable items in
