Cloud database AnalyticDB for PostgreSQL (formerly HybridDB forPostgreSQL) is a massively parallel processing (MPP) data warehouse service that provides online analysis of massive data services.
AnalyticDB for PostgreSQL PostgreSQL-based kernel build, compatible with ANSI SQL 2003, compatible with PostgreSQL / Oracle Database ecology, support row and column-storage mode. Both provide high-performance off-line data processing, and also supports high concurrency online analytical queries, the industry is competitive PB-level real-time data warehouse solutions.
Typical scene
1, data warehousing services
production trading systems, real-time data synchronization to AnalyticDB for PostgreSQL by data transmission services (DTS). Big data computing platform, or through data integration tools (DataX), the on-demand data into AnalyticDB for PostgreSQL. AnalyticDB for PostgreSQL support for complex ETL clean up the massive data aggregation process, while these tasks can also be scheduled and arrangements Dataworks.
2, online analysis platform
AnalyticDB for PostgreSQL supports a variety of BI tools, including Ali cloud QuickBI, large screen display DataV, as well as the industry mainstream BI tools, including Tabular and so on. AnalyticDB for PostgreSQL by vectorization computing, intelligent indexing mechanism, high concurrency analysis can be completed inquiries, respond within milliseconds to support the company's online data analysis to explore.
3, Lake data analysis
AnalyticDB for PostgreSQL via an external table mechanism, highly parallel data on direct access massive cloud storage OSS, Ali cloud to build a unified platform for data analysis lake.
Advantages
for major OLAP business scenarios, AnalyticDB for PostgreSQL has the following advantages.
1, ETL offline analysis scenarios.
The challenge complex SQL optimization, large-scale mass data aggregation analysis, AnalyticDB for PostgreSQL offers technical advantages are:
Supports standard SQL, OLAP window functions, stored procedures.
ORCA distributed SQL optimizer, free tuning complex queries.
MPP full multi-node parallel computing, PB-level data-second response.
High Performance column based scan large table storage, and high compression ratio.
2, high concurrency analysis to explore the online scene.
Dimension Data challenge facing any immediate exploration, real-time data warehousing updates. AnalyticDB forPostgreSQL technological advantages offered are:
High throughput data write, and update (INSERT / UPDATE / DELETE).
And a plurality of rows of memory index (Btree, Bitmap etc), point query returns milliseconds.
Support distributed transactions, standard database isolation levels, support HTAP mixed load.
