PostgreSQL 101: Indexes and Index Types
The index types supported by PostgreSQL are B-tree, hash, GiST, GIN, and BRIN. The PostgreSQL database supports single-column, multicolumn, partial index, unique index, expression index, implicit index, and concurrent indexes.
PostgreSQL 101: Index Maintenance
Regardless of the brand, indexes in every database have the potential to cause problems in systems subject to high write/delete operations. Just as tables can bloat, indexes can bloat as well. Non-primary key indexes can bloat even during normal insert operations. On the other hand, autovacuum handles this bloated...
PostgreSQL – JSON Data Type Operations
It was a big deal when the JSON data type and supporting functions began to be supported with PostgreSQL version 9.2. Today, while other databases are starting to support this data type one by one following PostgreSQL, there is well-established JSON support in PostgreSQL. JSON, web applications, JavaScript...
PostgreSQL Performance: max_connections
max_connections holds an important place in PostgreSQL performance settings. During the opening, closing, and reopening of each connection, a surge and resource consumption occurs. Therefore, this value can be expressed in the hundreds on powerful hardware, but if your need is greater, for example, if you need thousands of connections...
What's New in PostgreSQL 10
The new major version of PostgreSQL, version 10, has been released. Among the many innovations that come with PostgreSQL 10, flexible logical replication stands out as an alternative to physical replication, promising seamless transitions even during major updates. In addition, partition support has arrived in place of table inheritance, and parallel query capability...
Linux 101: Which I/O Scheduler?
Whether you perceive it as going overboard with performance optimization or engaging in an intellectual technical bickering, if a client asks, "Which I/O scheduler do you recommend you use?" you have to answer. There isn't just one answer to this question, there are multiple...
PostgreSQL Optimization on Power Systems
Community PostgreSQL is provided with the most basic configuration, capable of running even on a POS terminal, and strictly requires reconfiguration and performance tuning to meet enterprise usage needs. Performance optimization for PostgreSQL, which works in close relation with the operating system, is not just hardware...
PostgreSQL’s Foreign Data Wrappers
Foreign data wrappers, extensions in PostgreSQL that make it possible to connect to external systems and retrieve and query data, have been available for a very long time, but recently they have both matured significantly and found more use cases.
Citus: Real-Time, Horizontally Scalable PostgreSQL Data Pipeline
A architecture that "distributes" PostgreSQL databases horizontally across multiple systems using sharding and replication, enabling real-time (sub-second) responses over large datasets by executing incoming queries in parallel processes across these systems thanks to its custom query engine.
