This is especially the case when the table grows over 10GB, MongoDB does not have this issue. Adding a new column would require one to run an ALTER operation which is quite expensive in terms of performance as it will have to lock up the entire database. On the other hand, MySQL is table oriented whereby each row must have the same columns as the other rows. MongoDB therefore allows one to add various types of data as per needs change. Of course, there are scenarios that can opt one to use undefined schema for example if you are de-normalizing a database schema or when your database is growing but your schema is unstable.
MONGODB SPEED VS MYSQL UPDATE
This means there is no restriction on document structure for every insert or update hence changes to the data model won’t have much impact. MongoDB is schemaless such that different documents in the same collection may have the same or different fields from each other. MongoDB can load a high volume of data as compared to MySQL and with built-in sharding, it is easy to partition and spread out data across multiple servers as a way of utilizing the cost-saving solution as per the cloud-based storage merits.
For MySQL, there is no clear official solution for providing failover between master and slave in the event of a failure.Ĭloud-based storage solutions require data to be smoothly spread across various server to scale up. Besides, recovery from a cluster failure is instant, automatic and safe. In a nutshell, setting a set of servers that can act as Master-Slaves is easy and fast in MongoDB than MySQL. Besides, due to comprehensive secondary indexes and native replication, creating a backup for a MongoDB database is quite easy as compared to MySQL since the latter has integrated replication support. This is because it takes very less time for the active secondary nodes to elect a new primary node thus easy administration at the point of failure. High Availability and Cloud Computingįor unstable environments, MongoDB provides a better handling technique than MySQL. On the other hand, MySQL has data stored in an individual table hence at some point one has to lookup on the entire table before doing a write operation. This implies that the performance is dependent on two key values that are the design and scale out. MongoDB is mainly structured such that documents are the basis of storage which promotes huge query and data storage. In the case of updating which is a write operation, MongoDB takes 0.002 seconds to update all student emails whereas MySQL takes 0.2491s to execute the same task.įrom the illustration, we can conclude that MongoDB takes way lesser time than MySQL for the same operations.
Observing some of the querying behaviours of the two, we can summarize the different operation requests for 1 million documents in the illustration below. But in the case of MongoDB, with the availability of insertMany() function, you can safely do the multiple inserts. This feature is not available in MySQL hence for instance if you are to save a lot of data to your DBM at once, in the case of MySQL you will have to do it one by one. MongoDB by default encourages high insert rate over transaction safety. This is one of the major benefits of using MongoDB over MySQL especially when a large set of unstructured data is involved. However, in this article, we are going to discuss the pros of using MongoDB over MySQL. Every selection has got its pros and cons but your choice will mainly be determined by your application needs since both serve in different niches. On the other hand, MongoDB a non-relational DBM has come to rise basically due to its ability to handle a large set of data. The choices for relational DBMS are quite obvious: MySQL, PostgreSQL and MS SQL. In the past years, the Relational DBMS where more dominant but with recent data structure trends the non-relational DBMS are becoming more popular. There are so many database management systems (DBMS) to choose from ranging from relational to non-relational DBMS.
