Learned how Kafka uses sticky partitioning to optimize batching. This significantly reduces latency when producers don't specify a key, as it keeps records pinned to a single partition until the batch is full.

Explored how to use unsafe pointers in Go to achieve zero-copy deserialization for Protobuf messages. Great for high-throughput systems like Shadowstream.

Dived deep into Leveled vs Tiered compaction for GopherDB. Leveled compaction reduces read amplification but increases write amplification—a classic trade-off in storage engine design.
