Open source PostgreSQL extension age for graph database was announced as the top-level project of Apache Software Foundation

Apache AGE,“ Graphic extension ” Recently announced as Apache Software foundation top projects (TLP). What's the importance of this ？

The project started in 2019 Years as a AgensGraph（Bitnine Global Of PostgreSQL Multi model database Branch ） The extended development of , And in 2020 year 4 The moon enters Apache The incubator .Apache Incubator is the main entry path for projects and code bases that want to be part of it Apache The efforts of the software foundation . For a graduate from an incubator to enter TPL In terms of projects , Show great maturity and community participation . It provides confidence for the life of the project , Good news for those who want to adopt it .

As for the project itself ,AGE Is a graphic database project , It adds graphic analysis function to the traditional relational data platform . It's based on PostgreSQL, It aims to create a multi model database that can process relational model and graphical model data at the same time , So that users can use the standard ANSI SQL And graphic query language openCypher, Fill in the unsatisfied “ The best of both worlds ” Niche market .

just as Postgres Community advocates Mehboob Alam As explained ：

Integrating traditional analysis and real-time graphic intelligence will change the rules of the game , and AGE Will play an important role in this exciting future .

As mentioned earlier ,Apache AGE Support openCypher Graph query language .Cypher By the first Neo4j contribution , Has been 10 A variety of products and tens of thousands of developers use . It is a query language , Allows you to retrieve data from charts . It's like for graphics SQL, And receive SQL Inspired by the , So it allows you to focus on what data you want to get from the graph , Not how to get it .

I am here “Neo4j Online course introduction ” The report Explored Cypher , Of course ,Neo4j Is a purely graph based database , And AGE The graph relation fusion of is different . This free course is about Cypher Basic knowledge and opportunities for different types of database management systems and their evolution ：

When dealing with connections between many tables , Relational database system can't really deal with . And then , When it is found that the classical database system cannot cope with the amount of data generated in the era of big data , The first crack began to appear . therefore ,NoSQL Database came into being . But to improve performance , They got rid of ACID.

The next step is the document database , You can index the contents of the document , So that you can also find documents based on their contents . But then you need to be able to find cross referenced data , Therefore, the graph database appears . Designed for online transaction processing (OLTP) The system is used together to build , They can store relationships and connections as first-class entities , It can also be stored in ACID Next .

go back to AGE, The project recently released Apache AGE v1.0.0-incubating, At present, for PostgreSQL 11 Version development , And will support PostgreSQL 12、13 And all the future PostgreSQL edition .

Of course , This is due to PostgreSQL extensibility , This proves once again the added value and unpredictable value it has for its users . in fact , Recently released another very useful extension . stay pg_ivm Checked in pg_ivm - Steroids The materialized view of ：

pg_ivm yes PostgreSQL 14 Expansion module for , It provides incremental view maintenance (IVM) function . This means that the materialized view is updated immediately after modifying the base table .

pg_ivm Gives the answer to the old question of when to refresh materialized views . As a review or reminder , The materialized view is compared with the ordinary view , The former keeps a copy of the referenced data to speed up the query , Because you actually query the copy , The latter performs real-time queries every time .

AGE Add a strong expansion ecosystem , give PostgreSQL Extra superpowers . In its Github repo Check out .
