In this age of computer popularization, most families have been popularized to terabytes of hard drives, and some even hang up 3-4 terabytes of data disks in a row! According to Candy, a DBA friend of Candy, who has more than 20 terabytes of data on his home computer, should even do a raid for fear of loss. Every time you see the so-called "big Data" once, candy

ogg process split (single table split into multiple processes)Overview:The OGG process split describes how to split multiple tables in one inbound process into another process. This article will focus on how to use multiple processes to library a single table at the same time. Applicable conditions:1) The inbound process synchronizes only one table, but still has a delay of 2) target segment host CPU, memory pressure is not large enough to have sufficient resources to add a new inbound processTh

Data scale BigTable database systems (such as HBase and Cassandra) are designed to meet the needs of massive data storage. The massive data scale mentioned here refers to the size of data stored in a single table in terabytes or petabytes. A single table is composed of hundreds of billions of rows and hundreds of billions of columns. When we mention the data scale, we have to say that we are currently at NoSQ Data scale BigTable database systems (such

Hbase Overview Big Data and NoSQL's past lifeTraditional relational database processing is based on a comprehensive ACID guarantee that follows SQL92 's standard table design pattern (paradigm) and data type, based on the SQL language's DML data interaction. For a long time, this kind of information construction based on relational database is developing well, but it is restricted by the data model provided by the relational database, and for the data set of pre-defined model, the relational dat

My last blog, "Two modes of Big Data Processing", discusses the large-format memory-based streaming processing and hard disk-based storage processing. Compare these two processing modes, because the memory processing performance is the hard disk's n magnitude, so the stream processing efficiency is much higher than the storage processing, but the stream processing itself has a disadvantage, or is a worry, last time did not mention, today to say.This depends on the fundamentals of data Processing

ORACLE Database is a large-scale relational database that can store terabytes of data. Therefore, it is critical to ensure the security of such data, we have developed a complete ORACLE database backup system. For your reference. ORACLE databases run in either of the following ways: ARCHIVELOG ORACLE Database is a large-scale relational database that can store terabytes of data. Therefore, it is critical to

In addition, Linux operating system users also need a lot of new features that the Ext4 file system itself does not provide. While these requirements can be met through some software, performance can be impacted and better performance is achieved at the file system level.EXT4 File SystemEXT4 also has some obvious limitations.
