That means the entire dataset was being read through a single JDBC connection.

No parallelism.
No distribution.
Just one executor doing all the work.

Spark wasn’t slow.
I had accidentally made it single-threaded.

Day 34 of the Winter Arc.

Winter doesn’t weaken — it refines.
Less noise. Fewer excuses.
Sharper focus. Stronger systems.

This is pressure doing its job.

[PrakashJain 🇮🇳 @code_n_learn]

Day 33 of the Winter Arc.

Still no shortcuts.
Still no applause.
Just systems running, habits locking in, progress stacking quietly.

This is how long games are won.❄️🔥

Day 32 of the Winter Arc.

No hype today.
Just showing up, doing the work, fixing what broke yesterday.
Discipline isn’t loud — it’s repetitive and slightly boring.
That’s how it compounds.

Winter Arc Workout · Day 32
The grind didn’t get lighter— I got sharper.
Every rep was a reminder that consistency is a quiet weapon.
No flash. No shortcuts.
Just pressure, discipline, and a mind that refuses to fold. The winter arc continues.
