Community It has a large community support but its main focus is on maintaining the existing features. Unlike MySQL, Postgres has large community support which works to enhance the capabilities of PostgreSQL. Installation of PostgreSQL In this part of the blog, we will set up the dynamic environm...
It is important for DBAs or DevOps to be able to tune and extend their production systems without interrupting service. Thus, we continue to ensure that MySQL is leading in this area. In 5.7 we have delivered the following: We have provided a way to enable GTIDs online (WL#7083), so ...
Yes. By understanding metadata, you can design efficient queries and even apply indexing based on insights for faster search results. How is metadata pivotal in data warehousing operations? Metadata is central in ETL processes in data warehousing, assisting in data extraction, transformation, and load...
Thus, we continue to ensure that MySQL is in the front in this area. So far in 5.7 we have delivered: Resize the InnoDB Buffer Pool Online (WL#6117). This work adds the capability to change the value of innodb_buffer_pool_size dynamically. This provides the ability to tune the buffer...
instead computed by the server when the row is created or updated, using the expression specified by the user as part of thetable definition. Generated columns can either be materialized (stored) or non-materialized (virtual). See Evgeny Potemkin’s article “Generated Columns in MySQL 5.7.5“...
What is the better way of indexing the foreign key? Create Table table3( t3_id int not null auto_increment, t1_id int not null, t2_id int not null, primary key (t3_id), index IX_index (t1_id, t2_id), // this is my concern constraint FK_t1 foreign key (t1_id) ...
Finally, efficient indexing and optimization techniques in SQL enable quick data retrieval and processing, even with extensive datasets. These techniques ensure that queries run efficiently, saving time and computational resources, which is invaluable for large-scale data analysis. ...
It is document-oriented: As we know that MongoDB is a NoSQL database, instead of having data in a relational format, it stores the data in documents. This feature of MongoDB makes it very flexible and adaptable to real-world business situations and requirements. It provides indexing: Mongo...
In the world of database management, the choice between MySQL and PostgreSQL depends on your database’s specific needs. MySQL is known for its speed and ease of use. On the other hand, PostgreSQL excels when it comes to advanced features and extensibility. However, regardless of which DBMS...
Rapid query processing.SQL enables rapid query processing, enabling users to retrieve, manipulate or store data quickly and efficiently. However, optimizing queries for rapid processing involves a combination of proper indexing, query optimization and database design considerations. ...
