PostgreSQL has surged forward in capability and market acceptance in recent years like no time before as the community responded to market forces and enhanced and extended the database in critical areas. Today's PostgreSQL has achieved new levels of usability, scalability and capacity for new workloads. Marc Linster, Senior Vice President of Products and Services at EnterpriseDB, delivered this presentation at PG Open 2014. He covered the powers of PostgreSQL today compared to the vision taking shape just a few short years ago. He addressed how performance and scalability has advanced to support enterprise resource planning solutions for global brands through EnterpriseDB's work with Infor, the world's fourth-largest ERP vendor. Finally, Linster discussed how capacity to support new NoSQL workloads has expanded and explored the new toolkit, PG XDK.

- 11. Standard Objections • SQL databases can’t handle NoSQL data types − Postgres can (JSON and KVP) • SQL databases are too slow and can’t ingest the data fast enough − Postgres can keep up − We ran the tests − Benchmarks are public − Great feedback • SQL databases can’t support Web 2.0 development approaches − Postgres can − Support unstructured and structured data in the same environment − Move data from unstructured to structured (and back) − Use Web 2.0 languages inside the database (e.g.: PL/V8) or in the application (node.js) − Integrate NoSQL data (FDW) © 2013 EDB All rights reserved 8.1. 11
- 12. JSON Performance Evaluation • Goal − Help our customers understand when to chose Postgres and when to chose a specialty solution − Help us understand where the NoSQL limits of Postgres are • Setup − Compare Postgres 9.4 to Mongo 2.6 − Single instance setup on AWS M3.2XLARGE (32GB) • Test Focus − Data ingestion (bulk and individual) − Data retrieval © 2013 EDB All rights reserved 8.1. 12

This lead to truncation of the MongoDB size by approx. 25% of all records in the benchmark. Thank you Alvaro Tortosa!
- 15. Performance Evaluations – Next Steps • Initial tests confirm that Postgres’ can handle many NoSQL workloads • The test scripts are publically available https://github.com/EnterpriseDB/pg_nosql_benchmark • EDB encourages community participation to better define where Postgres should be used and where specialty solutions are appropriate • Join us to discuss the findings at http://bit.ly/EDB-NoSQL-Postgres-Benchmark © 2013 EDB All rights reserved 8.1. 15

Notes de l'éditeur
- -Welcome -Me -Apologies for Tom
- -Growing 84% last year; similar this year -Global -DB Product/Development company -Main products -Training & Professional Services -Committed, platinum Sponsor
- -These are the market forces that are shaping the future for PostgreSQL: --on one end are the smaller applications; web applications and app developers who need ease of use and rapid deployment --on the other end you have large, enterprise applications who need advanced features, security, scalability and HA for mission critical applications -Postgres occupies a middle-ground position and as we noted earlier has been gradually expanding in both directions -The emergence of new workloads & cloud will increasingly grow in shaping future customer needs and require RDBMS’s to expand capabilities (as noted by Gartner) These are the market segments we will need to address to ensure positive future growth
- Easy to use: -Diagnosing problems – People find this hard. -The out of the box configuration should be more optimized for the common use case. -Can we make the installation experience even easier? -Continually seek opportunities to win the cloud. High end Enterprise: -Need to continue to work to take advantage of all the resources of a single machine. There are many machines with 256 processors. -Horizontal Scale – This is a big issue for the cloud and in general. You can figure out ways to do it if you are very smart. Can we lower the the brain power required to do it? -Diagnostics is a request from every audience. NoSQL / New SQL -We are not going to reach all their use cases. -However, we should integrate well with them. -Continue involvement and work on the new data types is important.
