As a financial grade distributed transaction database product ,GBase 8c Global transactions with strong consistency 、 Computational storage separation 、 Flexible data distribution 、 Flexible deployment 、 Online expansion and contraction 、 Online upgrade 、 Data highly available 、 High security 、 Different live 、 Efficient data loading 、 Cluster backup recovery 、 Easy maintenance 、 Standardization 、 Compatible with domestic ecological and other technical features .

1. 1. 1. Strong consistency global transactions with automatic fault tolerance

GBase 8c The two-phase commit protocol and global transaction number are used to ensure the strong consistency of global transactions , Each cross node transaction , All or nothing , All or nothing , Some node transactions will not succeed , Other node transactions fail , Achieve strong consistency of global transactions .GBase 8c The transaction processing of has automatic fault tolerance , After a node that is processing transactions fails , The new node will continue the unfinished transaction , Without requiring the application to re request .

1. 1. 1. Computational storage separation

GBase 8c use shared nothing framework , Separation of computing and storage . Can be based on business needs , Horizontally expand the computing power and storage capacity respectively , Achieve the goal of reducing total cost of ownership .

1. 1. 1. Flexible data distribution

Users can meet the needs of business scenarios , Choose a data distribution strategy , So as to improve the performance 、 Get the best match between reliability and flexibility .

GBase 8c Support replication tables and distribution tables . Replication tables are used to store data that is read-only or read more than write less , Joint queries with distribution tables can be performed locally , So as to greatly improve the performance of queries . Distribution tables are used to store large-scale data in a single table , adopt Hash And so on , Reduce the amount of data in a single table , Improve data reading and writing performance .

1. 1. 1. Flexible deployment

  Users can according to their own IT Infrastructure construction , Combining performance 、 convenient 、 Comprehensive consideration of safety and other needs , Choose to GBase 8c Deployed in different environments .GBase 8c Support physical machine deployment 、 Virtual machine deployment 、 Container deployment 、 Private cloud deployment and public cloud deployment .

1. 1. 1. Online expansion and contraction

GBase 8c Support online capacity expansion and reduction , When expanding or shrinking , Data is automatically redistributed , The application system has no perception . During online capacity expansion and reduction , Uninterrupted business use , Ensure the continuous availability of the system .

1. 1. 1. Online upgrade

GBase 8c Online upgrade through gray publishing , During online upgrade , The system performance is only temporarily affected , Normal business access is not affected .

1. 1. 1. Data highly available

GBase 8c Ensure the high availability of the cluster through redundancy mechanism , Master-slave replication is used between multiple data copies to ensure data consistency .GBase 8c Support synchronization 、 Asynchronous and semi synchronous replication modes , Let users find a balance between high availability and high performance .GBase 8c Support automatic recovery of faults , No manual intervention required .

1. 1. 1. Security

GBase 8c Provide perfect users 、 role 、 Permission control policy , Improve the security of database cluster ; Support detailed audit logs , Flexible audit strategies can be configured , Record all logs related to database operations in the database , You can also realize audit management through graphical monitoring tools ; Support transparent data encryption ： Support data storage encryption , Support database password encryption , Support data encryption and compression ; Support related encryption functions , Such as AES、MD5、SHA1、SHA And other international standard algorithms , as well as SM1、SM2 Equal state secret algorithm .

1. 1. 1. Different live

GBase 8c Provide the deployment mode of multi activity in different places to meet the business requirements of high availability . Adopt the high availability deployment mode of multi activity in different places , You can achieve RPO=0,RTO Second level of high availability , Provide computer room level disaster recovery capability and city level disaster recovery capability .

1. 1. 1. Efficient data loading

GBase 8c Policy based data loading mode , It can ensure the balance between data loading speed and access performance .

1. 1. 1. Cluster backup recovery

The cluster has the ability of global backup and recovery , Support full backup 、 recovery , Support incremental backup 、 recovery .

1. 1. 1. Easy maintenance

Provide graphical deployment configuration 、 Operation and maintenance monitoring 、 Data synchronization 、 Backup and recovery and other operation and maintenance functions , Reduce the difficulty of operation and maintenance , Improve operation and maintenance efficiency .

1. 1. 1. Standardization

Support SQL92、SQL99、SQL 2003 ANSI/ISO standard , Support ODBC、JDBC、ADO.NET And so on ; Support C API、Python API Such as the interface .

1. 1. 1. A variety of ecological support

GBase 8c Distributed transaction database has rich surrounding ecological support ：

1. Support powerful GIS （GIS）.GBase 8c Support PostGis plug-in unit , It can effectively support spatial geographic data storage , As a spatial database , Efficiently manage spatial data 、 Data measurement and geometric topology analysis .
2. Support non relational data types JSON.GBase 8c Not just a distributed transactional database system , It also supports non relational data types JSON.
3. Support Foreign Data Wrappers（FDW）.GBase 8c adopt FDW Support user access SQL Query and access data outside the database cluster .FDW Function provides a set of programming interfaces , Users can carry out plug-in secondary development , Establish data channel between external data source and database . At present GBase 8c Support oracle_fdw、mysql_fdw、postgres_fdw, And non relational database redis_fdw、mongodb_fdw, big data hive_fdw、hdfs_fdw etc. . adopt FDW,GBase 8c Access to data from multiple existing data sources .

Compatible with domestic ecology .GBase 8c Compatible Godson 、 Feiteng 、 Kun Peng 、 Shenwei 、 Haiguang and other domestic products CPU; Compatible with Kirin 、 Tongxin and other domestic operating systems ; Compatible with domestic products CPU Server for .
