I have ~4 years in Data Engineering (Kafka, Elasticsearch, K8s, Redis, Ops, SRE, DevOps and many things etc.), and I'm now going deep on Spark — joins, shuffles, skew, the Spark UI. Not looking for someone to spoon-feed me, just someone I can rubber-duck with or who'll tell me when my mental model is wrong. Seriously, solo learning this Apache Spark is becoming very difficult for me as I have started to make my hands dirty. Anyone up for occasional async questions on Discord/Reddit? Pleaseeeee...
