If you are new to PostgreSQL the most common challenge you face is about how to tune up your database environment.  When PostgreSQL is installed it automatically produces a basic postgresql.conf file. This configuration file is normally kept inside the data directory depending on the operating system you are using. For example, in Ubuntu PostgreSQL places the configurations (pg_hba.conf, postgresql.conf, pg_ident.conf) inside /etc/postgresql directory. Before you can tune your PostgreSQL database, you first have to locate the postgresql.conf files.  But what are the right settings t ..read more

Amazon RDS for PostgreSQL is a managed service for PostgreSQL available as part of Amazon Web Services. It comes with a handful of management functions that are intended to reduce the workload of managing the databases. Let’s take a look at this functionality and see how it compares with options available in ClusterControl. PostgreSQL Deployment PostgreSQL RDS PostgreSQL RDS supports numerous versions of PostgreSQL, starting from 9.5.2 up to 12.2: For Aurora it is 9.6.8 to 11.6: You can pick if the cluster should be highly available or not at the deployment time. ClusterControl ClusterContr ..read more

This is the second part of my blog “My Favorite PostgreSQL Extensions” wherein I had introduced you to two  PostgreSQL extensions, postgres_fdw and pg_partman. In this part I will explore three more. pgAudit The next PostgreSQL extension of interest is for the purpose of satisfying auditing requirements by various government, financial and other certifying bodies such as ISO, BSI, and FISCAM, etc. The standard logging facility which PostgreSQL offers natively with log_statement = all is useful for monitoring, but it does not provide the details required to comply or face the audit. The p ..read more

A wide range of resources are available for you when managing your PostgreSQL database clusters remotely. With the right tools managing it remotely is not a difficult task.  Using fully-managed services for PostgreSQL offers an observability that can deliver most of what you need to manage your database. They provide you with an alerting system, metrics, automation of time-consuming system administration tasks, managing your backups, etc. When running on-prem it’s a different challenge. That's what we'll cover in this blog. We'll share tips on managing your PostgreSQL database cluster re ..read more

Database User Management is a particularly important part of data security, as we must understand who is accessing the database and set the access rights of each user. If a database does not have a proper user management, user access is going to get very messy and difficult to maintain as time goes on. MongoDB is a NoSQL database and document store. Applying the RBAC (Role Based-Access Control) concept is key to implementing proper user management to manage user credentials. What is Role Based Access Control (RBAC)? RBAC is an approach which restricts the system only to authorized users. In a ..read more

Using a VPN connection is the most secure way to access a network if you are working remotely, but as this configuration could require hardware, time, and knowledge, you should probably want to know alternatives to do it. Using SSH is also a secure way to access a remote network without extra hardware, less time consuming, and less effort than configuring a VPN server. In this blog, we’ll see how to configure SSH Tunneling to access your databases in a secure way. What is SSH? SSH (Secure SHell), is a program/protocol that allows you to access a remote host/network, run commands, or share inf ..read more

InnoDB buffer pool is the most important memory area to allocate to get decent performance. Let's see how to check if it's big enough. The post Is InnoDB Buffer Pool big enough? appeared first on Federico Razzoli ..read more

The database tier is one of the most important layers in a system architecture. It must be set up correctly from the beginning due to it being stateful, it is harder to scale as compared to other tiers. If the growth is exponential, the initial decision might get caught in the middle with outrageous total cost of ownership (TCO) which could inhibit database scaling and eventually affect business growth. In this blog post, we are going to look into some tips on how to reduce the overall TCO of our production database infrastructure costs. Use Open-Source Software & Tools Using open source ..read more

Time for the next blog post about MySQL bugs! The previous one covered some bugs I considered interesting in March, this one will be about community bug reports that I've picked up since March 26, 2020. I'd better review bug fixed in MySQL 5.7.30 instead of this, but it is still not released, even though we know it must get some important security fixes based on "Oracle Critical Patch Update Advisory - April 2020" recently published. As usual, I am mostly interested in replication, InnoDB, optimizer and few more categories. Here is the list: Bug #99082 - "Problem with replication: XA tr ..read more
