A big thanks to a team of efficient robots, the Apache Hadoop ecosystem, While these tools might be put to use for some data processing, real-time recommendations likely rely on faster, streaming-based solutions like Apache Kafka or Flink.

Think of Flume to be the ever-enthusiastic bookkeeper who constantly helps readers fetch the raw data from every corner of the TikTok library.

Every single like, share, and scroll gets counted! Then comes Kafka, the speedy book assistant, who zips and shifts this mountain of data to the nearby rack.

Do you think the bland and uninspiring raw data will interest readers?

This is where Storm comes in, it deconstructs the data, analyzes trends, and steers up insights quicker than what we call “viral video.”

Finally, we require a methodical bookkeeper who can divide and handle the data heap, MapReduce takes control!

Hope you found it easy to understand MapReduce’s operating process.
It declutters the data heap into bite-sized pieces.

Analyzes and sorts each one, and finally arrives at clear insights into user preferences and behaviors.

You must have understood all about deconstructing the processed data and the secret scheme behind TikTok’s bizarre personalization.

It’s similar to having an over-enthusiastic librarian who keeps whispering suggestions like, “You might also like this clip” or “Take a look at this meme, it will make you laugh! Do you agree?

Similarly, Every tap, swipe, and laugh is gained after such complete, detailed, proper analysis, and categorization, and they get sorted as per users’ personalized preferences.

Next time when you get lost in the platforms’ charisma, think of the versatile Big Data library-TikTok tech stack.
