Why does PySpark use credits?

Everything else on DataPathsala runs on lightweight containers that cost pennies per day. PySpark is different — each execution spins up a full Apache Spark JVM cluster:

Spark containers use 1 GB RAM + 2 CPUs per execution
60-second timeout vs 15 seconds for SQL/Pandas
JVM startup overhead regardless of solution complexity

Credits are priced to cover infra costs, not to profit. ₹5 = 2 PySpark submits.
