Covers concrete big-data mistakes and fixes: choosing Hadoop for a 20 GB set wastes time and ops, partitioning and columnar Parquet files plus bucketed sort-merge joins cut I/O; Kafka originates as LinkedIn’s data-integration layer and benchmarks show 2M TPS with ~2 ms latency; Cassandra’s soft deletes leave tombstones by default for 10 days and wreck scans unless schema and retention are redesigned; use HyperLogLog-like sketches to deduplicate — ~1.5 kilobits per billion distinct — and enable production-grade security.
