The data is structured as specified in the FHIR message exchange format standards. The dataset comes from an existing project in use with Mongo and is composed of several collections. PidFilePath: /var/run/mongodb/mongod.pid # location of pidfile On top of that, for security reasons, on this paper all the mentioned fields have been altered in the name and in their content, and not relevant ones completely removed.īoth versions of Postgres and Mongo that we’ve used are vanilla versions. As generic good practice, and as demanded by law in case of medical records, all data is anonymized, and subsequently made accessible to employees. All tests were repeated over multiple runs, and only the average is reported.Īs dataset, we used anonymized data derived from real data. This setup allows read-only benchmarks, since there are no separate set of disks for data and journaling.īoth Mongo and Postgres were installed on the machine, and only one product was running at the time. While not optimal (I would’ve prefered bare metal), this is what we had available for testing. It’s the same virtual machine we already used in the past to run tests on several different products (like in the previous blog post when I compared InfluxDB to Postgres). We used a test machine running CentOS 6.8 equipped with one SSD disk, 10 GB RAM, and 4 cores. Now that you know ‘why’ we felt the need to experiment with both systems ourselves, I will tell you more about what we actually did to benchmark one product versus the other. topic is to us complex and vast, and we are more than willing to listen from you and hopefully learn from it. If you notice inaccuracy, mistakes, or anything that you want to discuss, please reach out to us. So here we are sharing our results for your consideration, and in the hope our efforts might turn handy to some other people out there. That is the reason behind the decision to perform some tests by ourself and start discussing with some numbers at hand. Me and my colleague Wouter discussed the topic and did some preliminary research trying to compare on query execution speed and disk space consumption.Īfter all that reading, learning, asking and studying, the conclusion was that we did not have a clue if Mongo was still the best choice to store our JSON data. Very recently, a new project has been kickstarted here at Portavita, and since Portavita uses both PostgreSQL and MongoDB, the following question arose spontaneously: which database is the most suitable to support our use cases? Since version 9.2, also PostgreSQL is able to talk JSON and several progresses have been made over the years making PostgreSQL more and more production ready to serve JSON efficiently.
Here at Portavita we work with a lot of data in the JSON format and we store it in MongoDB, a open source, non-relational database (NoSQL) born in 2007. Relational Database Management system Database is created in table formatĭatabase in form of documents sheet and some record may contain nested entries.Last Update: NovemAdded: Postgres table creation details Relational Database Management system’The database is created in the table format It uses a syntax similar to JSON and supports the storing of any type of elements: objects, physical files, etc. MongoDB is the non-relational database system most popular lately, because of the promptness and flexibility offered to your developments.
MariaDB is a database system originated as a fork for MySQL.All commands, interfaces, libraries and API that exist in MySQL also exist in MariaDB.
Mongodb performance vs postgres free#
It’s the free alternative to MySQL, counting on scalability and versatility levels that are very similar. Here are some of the basic difference between them. The three databases are used at a variety of application depending on the need. It offers higher speed of processing data and less response time for some specified application. Its a specialized DB build on non-relational document store architecture similar to JSON and support any type of file or elements. MongoDBis a cross-platform document-oriented database. The said architecture has many advantages over MySQL in areas of performance and redundancy.
Mongodb performance vs postgres software#
As a database server, its primary function is to store data, securely and supporting best practices, and retrieve it later, as requested by other software applications, be it those on the same computer or those running on another computer across a network. PostgreSQLis an alternative to MySQL working on ORDBMS (Object-Relational Database Management System). It was developed by the same developer as that of MySQL except for the fact MariaDB offers many more additional functionalities to the MySQL engine. MariaDBis considered as the fork(replica) of MySQL database.
