Azure Data Studio – Switching from Management Studio (SSMS) to Azure Data Studio (ADS)

Azure Data Studio (formerly SQL Operations Studio) is a free Cross-Platform DB management tool for for Windows, macOS and Linux. Azure Data Studio (ADS) initial release was only compatible for SQL Server, however recently Microsoft released a PostgreSQL extension for ADS – so now you can also manage your PostgreSQL instance using ADS. For more details on Azure Data Studio PostgreSQL Extension, refer to my earlier posts

Azure Data Studio was initially only released for managing SQL Server, however with the today’s Microsoft’s announcement , it will now be possible to connect and manage PostgreSQL databases with Azure Data Studio PostgreSQL Extension (Sweet deal!)

PostgreSQL Table Partitioning Part III – Partition Elimination

Understanding Partition Elimination in PostgreSQL 11

This is Part-III for my series on Postgres Table partitioning. I’ll encourage you to also read Part-I and II on this topic.

PostgreSQL Table Partitioning Part II – Declarative Partitioning

Starting Postgres 10.x and onward, it is now possible to create declarative partitions.

In my previous post ‘postgresql-table-partitioning-part-i-implementation-using-inheritance‘, I discussed about implementing Partitioning in PostgreSQL using ‘Inheritance’. Up until PostgreSQL 9, it was only way to partition tables in PostgreSQL. It was simple to implement, however had some limitations like:

PostgreSQL Table Partitioning Part I – Implementation Using Inheritance

In earlier PostgreSQL versions, it was not possible to declare table partitions syntactically. Partitioning can be implemented using table inheritance. The inheritance approach involves creating a single parent table and multiple child tables (aka. Partitions) to hold data in each partition range.

In this post, I’ll discuss the implementation of table partitions using inheritance. However before proceeding, let’s first understand why do we need partitioning? Continue reading “PostgreSQL Table Partitioning Part I – Implementation Using Inheritance”

psql queries to quickly Identify & resolve database performance problems

As a seasoned data store engineer, I often find myself in situations where a production application is down due to some sort of performance issue and I am being asked “What’s wrong with the database?”. In almost all these situations, the database (along with the DBA) is automatically considered guilty until proven innocent. As a DBA, I need the tools and knowledge to help quickly determine the actual problem, if there is one, because maybe there’s nothing wrong with the database or the database server. My favorite approach to start with data driven performance analysis using PostgreSQL systems catalog

In below post, I am sharing bunch of PostgreSQL system catalog queries that can be used to troubleshoot database engine performance

Postgres system catalogs are a place where database management system stores schema metadata, such as information about tables and columns, and internal bookkeeping information. PostgreSQL’s system catalogs are regular tables.

Learning beyond SQL…PostgreSQL – Indexes

It’s been some time since I’ve blogged, even though I’ve been reading a lot all this while. One of the reason is that I couldn’t find enough compelling topics to write and share. Microsoft has been moving too fast with their SQL Server releases (2012, 2014, 2016….and we’re talking Linux beta right now) and I’ve always been catching up.

However, between all this, something has changed. Due to an ever-growing buzz around Open Source, I haltingly started looking into PostgreSQL. Truth be told, I’m starting from ground zero (so nothing to loose) and will be writing on topics that might sound too simple for some of you, nevertheless you may still find ’em helpful.

Identify queries that consume a large amount of log space in SQL Server

One of regular issues DBA’s get are about the T-log growth. Situations, wherein one “bad” or “poorly-designed” query can eat up entire T-log space, bring the free space to zero and then bring your application down. The cause and remedy of most these issue is discussed in this KB # 317375(I’m big fan on Microsoft KB’s).
