How to Configure a Databricks Cluster to Process 10 TB of Data Efficiently

How to Configure a Databricks Cluster to Process 10 TB of Data Efficiently 🚀 Sizing a Databricks Cluster for 10 TB: A Step-by-Step Optimization Guide Processing 10 TB of data in Databricks may sound intimidating, but with a smart cluster sizing strategy, it can be both fast and cost-effective . In this post, we’ll walk through how to determine the right number of partitions, nodes, executors, and memory to optimize Spark performance for large-scale workloads. 📌 Step 1: Estimate the Number of Partitions To unlock Spark’s parallelism, data must be split into manageable partitions . Data Volume: 10 TB = 10,240 GB Target Partition Size: ~128 MB (0.128 GB) Formula: 10,240 / 0.128 = ~80,000 partitions 💡 Tip: Use file formats like Parquet or Delta Lake to ensure partitions are splittable. 📌 Step 2: Determine Number of Nodes Assuming each node handles 100–200 partitions effectively: Without overhead: 80,000 / 100–200 = 400 to 800...

🚀 Mastering Git Basics 🚀


⭐ **ls**: List contents inside the folder
⭐ **mkdir <folder_name>**: Create a project
⭐ **cd <folder_name>**: Navigate into a folder
⭐ **git init**: Initialize a Git repository
⭐ **touch names.txt**: Create a new file
⭐ **git status**: Show directory changes
⭐ **git add .**: Add all untracked files
⭐ **git add file.txt**: Add a specific file
⭐ **git commit -m "message"**: Commit changes with a message
⭐ **vi file.txt**: Edit a file
⭐ **cat names.txt**: Display file content
⭐ **git restore --staged files.txt**: Unstage a file
⭐ **git log**: View commit history
⭐ **rm -rf names.txt**: Delete a file
⭐ **git reset <commit id>**: Restore file to a specific commit
⭐ **git stash**: Temporarily store changes
⭐ **git stash pop**: Apply stored changes
⭐ **git stash clear**: Clear stored changes
⭐ **git push**: Push changes to remote
⭐ **git branch feature**: Create a feature branch
⭐ **git checkout feature**: Switch to feature branch
⭐ **git merge feature**: Merge feature branch to main
⭐ **git clone <URL>**: Clone a repository
⭐ **git remote add upstream <URL>**: Add a remote upstream
⭐ **git fetch --all --prune**: Fetch and prune remote branches
⭐ **git pull**: Fetch and merge changes
⭐ **git reset --hard upstream/main**: Reset branch to a remote commit

⭐ **Git Rebase**:
Use `git rebase -i <1st commit id>` to squash multiple commits into one. Use "Pick" to keep a commit or "Squash" to merge it with the previous one. Example:

```
Pick commit id 1
S commit id 2
S commit id 3
S commit id 4
```

Now, all commits are merged into one commit.
