42. Migrating Away From Query Builders and ORMs in JavaScript or TypeScript

I spent the better part of a day moving a project completely off of the ORM we were using (TypeORM). Ever since I started doing web development, I’ve been using some kind of heavy abstraction on top of my database. Whether it’s Mongoose when I used MongoDB, or TypeORM when I decided to move to TypeScript and PostgreSQL. However, it turns out that ORMs and query builders aren’t so great. I used to be that person that thought ORMs and query builders did the job for me, and I used it as an excuse to not learn SQL (which is what everyone tells you NOT to do). Given the tools that exist today, I would wholeheartedly recommend doing it the opposite of how I did if you’re starting off new to these things — write your SQL stuff by hand, or with help from the tools I mention later in the post. It’ll feel really slow at first, but you’ll thank yourself later 😄

However, once the data reaches the cloud, the CSP has to decrypt the data to perform operation or computation.

57. Pilosa: A Scalable High Performance Bitmap Database Index

Big data is a big problem, at least getting anything useful out of it. Every day there is about three quintillion (the next step up is sextillion or one zettabyte) bytes of data created and only about 20% of it is structured and available to easily process. Nearly all useful processing that is done relies on a philosophy that is little changed from the green bar reports we were generating during the night shift and handing out up till the turn of the century. The whole map/reduce process is overnight batch processing, you aren’t working on live data, you are working on a snapshot, which might be fine for some companies, but for others, they need to be able to make decisions on high-velocity inbound data in near/real time.

How we store and manage data has completely changed over the last decade. We moved from an ETL world to an ELT world, with companies like Fivetran pushing the trend.

Redis, short for Remote Dictionary Server, is a BSD-licensed, open-source in-memory key-value data structure store written in C language by Salvatore Sanfillipo and was first released on May 10, 2009. Depending on how it is configured, Redis can act like a database, a cache or a message broker. It’s important to note that Redis is a NoSQL database system. This implies that unlike SQL (Structured Query Language) driven database systems like MySQL, PostgreSQL, and Oracle, Redis does not store data in well-defined database schemas which constitute tables, rows, and columns. Instead, Redis stores data in data structures which makes it very flexible to use. In this blog, we outline the top Redis use cases by the different core data structure types.
