The Easiest Way to Set Up Redis in 2022

Rammina — Sun, 15 May 2022 01:17:36 +0000

Have you been struggling with setting up Redis?

Or are you looking for an easier way of getting it up and running?

Either way, you might want to check out this FREE simple Redis setup that will save you time!

If you don't know what Redis is and what it is used for, don't worry. Here is a brief outline that will help you understand it better.

Redis: Multipurpose In-memory Data Storage

Let's go over a quick overview of Redis before discussing the setup method.

In short, Redis is an open-source, in-memory data store, that can serve as a cache, database, and message broker. On top of that, it supports various data structures.

In the database world, Redis is considered revolutionary.

It is an impressive hybrid of in-memory, schema-less design (noSQL) with high-performance, versatile data structures and modules that can be tailored to your data needs. On top of storing data in-memory, Redis allows for high durability and availability through backups and replication.

Redis is one of the most adept, optimal, multi-purpose databases out there: It scales horizontally like a key-value data store, but it also provides various functionalities, despite its simplicity.

You would want to use Redis to implement a highly available, in-memory cache to:

reduce data access latency
improve throughput
minimize the load on your SQL or NoSQL database and on your application itself

Alright, time to set up Redis!

Redis Cloud Setup

The easiest way of getting Redis up and running is by using Redis Enterprise Cloud.

This method reduces the likelihood of running into operating system-specific issues, such as the lack of Windows support for Redis. It also allows you to reach the cloud database endpoint anywhere, whether you are using other computers or VMs.

Short Outline of the Process

Sign up for an account on Redislabs.
Add a new subscription.
Create a new database.
Choose a protocol and modules.
Retrieve database information.

1. Redislabs Account Registration

First, you need a Redislabs account to be able to set up a database.

Thankfully, their registration process is hassle-free, since you can just sign up with either your Google account or GitHub account! If you have neither of the two, you can fill in the registration form.

For this example, I'm using GitHub to register for a Redislabs account.

2. Add New Subscription

Before you can set up a database, you'll need to have a subscription plan. Click New subscription.

Then, choose fixed plans.

Select the cloud vendor that you want to use. For this example, I'm using AWS.

You also need to choose which region you want the service to be located in, choose the closest one near where your application will be hosted.

For the FREE plan, you get 30MB of in-memory storage and no replication/high-availability.

Next, choose a subscription name that makes sense for your use case (e.g. your app's name). Then, click Create subscription.

You should now have a subscription number (Subscription #1715073) and the option to create a new database.

3. Create New Database

Now, you can proceed to create a new database!

You can do this by clicking New database on either the top-right of your screen or at the center.

Choose a database name that suits what you are doing with it (e.g. your app's name).

4. Choose Database Protocol and Modules

Select Redis as your database protocol. As for the modules you'll be using, you can choose both RediSearch and RedisJSON. These two modules are usually enough for most projects.

Click Activate database once you are done filling out the database creation form. After that, you just need to wait for Redislabs to finish setting up your database.

5. Retrieve Database Information

After the database is created, you're probably wondering how you're supposed to connect with the Redis data store.

You can look for the Public endpoint information on your newly created database.

Take note of the Redis hostname and the port number.

For this example, I have the public endpoint of redis-19827.c83.us-east-1-2.ec2.cloud.redislabs.com:19827. The hostname is redis-19827.c83.us-east-1-2.ec2.cloud.redislabs.com and the port number is 19827.

Note: You may also need a password to connect to your newly created Redis database.

Scroll further down the database information page.
Go to the Security section.
Retrieve your Default user password.

While you can use the default credentials to connect your Redis database, it is best to update it to a more secure one later on.

You can do it by clicking the Edit database and changing the information that you'd like updated.

Congratulations! You should have a Redis Cloud database successfully set up now.

Frequently Asked Questions (FAQ)

Which programming languages can I use Redis with?

Redis supports most modern programming languages. These include (and are not limited to) Node.js, PHP, Java, Python, Ruby, C#, C++, and so on.

Check your language and framework's libraries or packages for utilizing Redis. For example, Node.js has the node-redis npm package for interacting with a Redis database.

Am I going to be charged for this Redis set up?

If you choose the free, fixed subscription plan, you will not be charged.

However, the free plan does come with its limitations such as 30MB storage, lack of replication, 30 maximum connections, and so on. Usually, this is enough for local development needs, so don't worry about it too much.

Can't you just install and run Redis on Docker? That would be faster than clicking through all the GUI on Redislabs.

This tutorial aims to provide the easiest way to set up Redis.

One issue with a Docker set up is that it requires someone to know (or learn) how to configure Docker images and containers. This intermediate step can be intimidating for beginners who are just starting out.

Day 100 of 100 Days of Code & Scrum: My First Day at a New Job

Rammina — Tue, 15 Feb 2022 21:40:11 +0000

Great news!

I started my first day in a new full-time role as a Full-stack Developer today. Originally, this was supposed to be a part-time position, but much to my surprise, I was told today that I'll be given a full-time role. Obviously, I was delighted to hear that, and so I accepted the offer.

It's definitely one eventful way to end the #100DaysOfCode challenge.

Yeah, even I have a hard time letting all this sink in and accepting reality.

Yesterday

I reviewed table relationships and the different types of JOINs for SQL tables. Also, I finish reading the Introduction to the Nexus Guide.

Today

Without being too specific, I went through the first day of the onboarding process: being given access to the various resources, attending a few meetings, and familiarizing myself with the company I'll be joining.

Retrospective?

I'll most likely be busy for the rest of the week with onboarding and training, so I'll try to post my thoughts about the entire challenge and share a summary of my experiences either on this weekend or on the next one. I do have things I'd like to express with regards to #100DaysOfCode, so I'll get to it when I have the time.

Closing Remarks

I got used to blogging almost every night the past few months, so it's definitely going to feel weird not having to do this anymore. There were times that I felt like it was such a pain to write all this, but I think I'm going to miss this. It was definitely a meaningful challenge, and it was enjoyable interacting with other developers in the community.

Thank you for reading my blog posts about #100DaysOfCode, and thanks to everyone for their support!

I wish you all the best in your programming journeys.

Day 99 of 100 Days of Code & Scrum: Relationships Between Tables, Various JOIN Types in MySQL

Rammina — Mon, 14 Feb 2022 11:44:54 +0000

❤️ Happy Valentine's Day, everyone! ❤️

I love coding, so it's my Valentine, and I have been doing just that the entire day. Jokes aside, I took a relatively easy day today, spending time with my loved ones and having a bit of fun. Coding may be enjoyable, but I didn't want to grind all day on a special occasion.

Moving on, I reviewed various types of table relationships and the different types of JOINs, just so that I have a clearer understanding of them. Honestly, it's going to take me some time to intuitively understand when to use one over the others, but I suppose I should just practice more.

Anyway, let's move on to my daily report!

Yesterday

Grinded real hard learning about more complex data types, DATETIME utility functions, and logical operators in MySQL.

Today

MySQL

practiced using SQL JOIN to generate meaningful data by combining multiple relational tables.
reviewed the different types of JOINs:
- INNER JOIN - INNER JOIN keyword selects all rows from both the tables as long as the condition is satisfied.
- LEFT JOIN - returns all the rows of the table on the left side of the JOIN and matching rows for the table on the right side of JOIN.
- RIGHT JOIN - returns all the rows of the table on the right side of the JOIN and matching rows for the table on the left side of JOIN.
- FULL JOIN - creates the result-set by combining result of both LEFT JOIN and RIGHT JOIN. The result-set will contain all the rows from both the tables.
continued Colt Steele's MySQL course.

Day 98 of 100 Days of Code & Scrum: SQL Sunday

Rammina — Sun, 13 Feb 2022 12:07:53 +0000

Happy weekend, everyone!

Today, I spent most of the day learning MySQL. I dived deeper into various data types in SQL as well as their respective functions. Also, I learned about how logical operators in MySQL work, which isn't that different from how they work in other programming languages. One interesting thing I noticed is that string comparison in SQL is not case sensitive.

Anyway, let's move on to my daily report!

Yesterday

I practiced utilizing aggregate functions in MySQL and learned more about the Nexus framework.

Today

MySQL

I learned about more datatypes in SQL and their use cases such as CHAR, DECIMAL, FLOAT, DOUBLE, DATE, TIME, DATETIME, and TIMESTAMP.
practiced various DATETIME utility functions such as:
- DATE_FORMAT
- NOW()
- CURDATE()
- CURTIME()
- DAY
- DAYNAME
- DATE_ADD
- DATE_SUB and more...
learned about logical operators in MySQL, the common ones and interesting ones like BETWEEN, LIKE, IN, and more.
practiced using CASE statements for conditionally returning different values based on conditions.

Day 97 of 100 Days of Code & Scrum: Aggregate Functions in MySQL

Rammina — Sat, 12 Feb 2022 12:50:48 +0000

Hello there, everyone!

I spent my free time today practicing aggregate functions in MySQL, such as COUNT, MIN, MAX, SUM, and AVG. GROUP BY took a little bit of time for me to understand, but I eventually understood how it groups together related rows.

Anyway, let's move on to my daily report!

Yesterday

I did string functions practice in MySQL to get more used to them.

Today

MySQL

I learned how to utilize the most commonly used aggregate functions in MySQL, along with GROUP BY.

Day 96 of 100 Days of Code & Scrum: Stringed Along by MySQL

Rammina — Fri, 11 Feb 2022 12:19:32 +0000

Hello there, everyone!

TIL, SQL index starts with 1, not with 0. I'm really surprised at this fact, because I'm way too used to counting starting from 0 when programming. I find myself easily thrown off when mentally calculating index-related stuff in SQL, because of 1-based index. Either way, it's just something I need to take into account.

That aside, I spent most of my free time today learning string-related functions in MySQL. I didn't learn all of the functions in the MySQL string functions documentation, but I familiarized them. What I focused on were the most commonly used string functions.

Anyway, let's move on to my daily report!

Yesterday

I did basic CRUD practice exercises in MySQL to get more used to them.

Today

MySQL

I learned how to utilize the most commonly used string functions in MySQL such as:
- CONCAT - concatenates multiple strings together.
- UPPER - converts a string to uppercase.
- LOWER - converts a string to lowercase.
- REVERSE - reverses the order of characters in a string.
- REPLACE - takes in a string, and replaces substring with another substring.
- SUBSTRING - retrieves a substring from a string, starting and ending indices can be selected.
- CHAR_LENGTH - returns the number of characters in a string.
skimmed through MySQL string functions documentation.

Day 94 of 100 Days of Code & Scrum: Moving to MySQL

Rammina — Tue, 08 Feb 2022 12:25:37 +0000

Good day, everyone!

Today, I started learning MySQL and picked up some of the basics. I think I made the right choice being familiar with SQL first, as most of the SQL database management systems (such as MySQL, postgreSQL, and SQLite) use almost the same commands with a few differences between of them. As for the resource I'm using, I chose Colt Steele's MySQL course which is pretty fun and beginner-friendly.

Anyway, let's move on to my daily report!

Yesterday

I finished these two courses: Next.js & React by Maximilian Schwarzmüller and SQLZoo's SQL Tutorial.
also finished reading the Nexus guide for scaling Scrum.

Today

MySQL

I learned how to create, describe, and delete databases and tables in MySQL.

Rammina — Fri, 04 Feb 2022 10:11:03 +0000

Greetings, everyone!

Today, I fixed some styling bugs on the portfolio section of my business site. It's kind of funny that I didn't catch this for a month, because it was at a very narrow breakpoint range (around a width of 768px - 1024px) that I just overlooked. Oh well, at least it's fixed now, and I also made some styling improvements for the blog section and then added it to the homepage as well.
