Deep Dive into Citus: Improving Scalability in PostgreSQL
Tags: postgres, opensource, database, apacheag
Published: 2023-10-03 17:37:29

## Introduction
PostgreSQL and SQL are renowned for their ability to maintain data integrity and offer robust query capabilities. Among open-source database management systems, PostgreSQL stands out as a top choice. However, when working with extremely large datasets that require high levels of concurrent access, it can face limitations. To address these challenges, Citus provides an architectural solution that distributes data across multiple nodes. This approach enhances performance and optimizes hardware resource utilization.

## Architecture
Citus is designed around PostgreSQL servers that form a Citus cluster, with each server equipped with the Citus extension along with other extensions. It leverages PostgreSQL's extension APIs in two significant ways to modify the database's behavior:

- Replication of various database elements across all servers, encompassing custom types and functions.
- Introduction of two new table types, both optimized for increased scalability across multiple servers.
- Citus employs a technique known as sharding to achieve scalability. Sharding involves breaking down large databases into smaller chunks or shards and then distributing these shards across numerous nodes. This intelligent approach involves directing queries to the appropriate nodes and aggregating the results efficiently.

## Key Factors
Citus has some important attributes:

- Horizontal Scaling: Unlike vertical scaling, which aims to enhance the performance of existing machines, Citus achieves scalability by adding more machines to the cluster.
- Parallel Query Processing: Citus leverages the aggregate query processing capabilities of all nodes, enabling it to execute queries in parallel across multiple nodes, significantly boosting performance.
- High Throughput: Designed for large-scale data applications, Citus efficiently processes vast amounts of data and queries, avoiding bottlenecks and maximizing resource utilization.
- Multi-Tenancy Support: It facilitates the development of applications with multiple tenants, allowing data to be distributed across various distributed tables.
- Familiar Compatibility: Citus's compatibility with PostgreSQL ensures a smoother learning curve, particularly for those already familiar with PostgreSQL, as it allows users to utilize familiar PostgreSQL tools, extensions, and methodologies.
How to send SMS using 3G/4G Dongle and Docker
Tags: docker, devops, development, webdev
Published: 2023-10-03 17:21:24

Imagine that you are a System Administrator or your business is communicating with clients daily, for example sending information about unpaid invoices or reminders that there is a new invoice. Or you want to inform clients by promoting new products or secure password resets 2FA. You can do that with a TEXT Message ( Known as SMS ). Also, this is a great way to automate your systems and important notifications. The all above-mentioned are pretty easy to implement and do as nowadays mobile carriers in several countries have unlimited texts inside their subscriptions and also prepaid plans.

Once I was curious Is it possible somehow to get the advantage of a free SMS Text that a mobile carrier offers? And yes by doing research I found that there is a great software called wammu, so I started exploring, how it works and found out, that the old 3G/4G Dongle can be used in this case. First thing spending several hours, I got the option that wammu would make me a phone call when a correct command was executed. Then after several times compiling the wammu library I found that it can also send Text messages, but the issue was that if you have around 300 Text messages in 1 minute then wammu hangs the Dongle. So I started to do research from 0 and found Gammu is the same product as wammu, but for my Dongle I could send more than 2000 Text messages in one minute and yes I did a real live test my phone got spammed and no stuck messages, after sending the text messages the Dongle was active and no issues found. So I was running it for 4 months in a test mode to send me each hour a few randomly generated Text messages.

The full article you can find in my blog with all the How to.

Pioneering PLV8 for Apple Silicon: Embracing the Future of Arm64 Architecture
Tags: plv8, docker, python, extensions
Published: 2023-10-03 15:48:29

Hello, fellow developers!
Today, we're excited to share another milestone in our journey with PLV8. As you know, we've been working tirelessly to make PLV8 more accessible and efficient for developers around the world. Now, we're taking a giant leap forward by introducing support for the arm64 architecture, specifically for Apple Silicon, which includes the groundbreaking M1 and M2 chips.

Apple Silicon, a series of arm64 processors, has made waves in the tech world with its high performance and power efficiency. However, it also brought new challenges for developers due to its arm64 architecture. That's where we come in.

About a year ago, a developer from Sweden reached out to us. He was working with an M1 Mac and wished for PLV8 to be compatible with it. At that time, no one was offering this feature. We saw this as an opportunity to expand PLV8's capabilities and to help developers like him. So, we rolled up our sleeves and got to work.

The result? We've put together a Docker image for PLV8 that works seamlessly on the arm64 architecture, making it compatible with both M1 and M2 chips. It's like we've built a bridge, connecting the power of PLV8 to the potential of Apple Silicon. And the best part? We're the only ones doing this right now.

But we're not stopping there. We're committed to providing constant updates to our PLV8 image, ensuring it stays compatible with the latest versions of PostgreSQL and Apple Silicon. It's like we're on a never-ending journey, always moving forward, always improving.

So, if you're a developer working with an M1 or M2 Mac and PostgreSQL, our PLV8 image is here to make your life easier. Give it a try and experience the future of development today.
Check out our [GitHub repository](https://github.com/sibedge-llc/plv8-dockerfiles) for more details. And if you find our project beneficial, please give us a star. Your support helps us continue our work and helps others discover our project.

Ready to get started? You can download our [PLV8 image directly from Docker Hub](https://hub.docker.com/r/sibedge/postgres-plv8) and begin your journey with PLV8 on Apple Silicon.
