CAP v2: In a distributed system (a collection of interconnected nodes that share data.), you can only have two out of the following three guarantees across a write/read pair: Consistency, Availability, and Partition Tolerance - one of them must be sacrificed.

Consistency: A read is guaranteed to return the most recent write for a given client. Availability: A non-failing node will return a reasonable response within a reasonable amount of time (no error or timeout). Partition Tolerance: The system will continue to function when network partitions occur.

codebase

one-liner: more-than-once commit, written in scala, batching messages with logical offset, log segment file, 1 partition to 1 consumer, system page cache(no in memory cache), broker, zookeeper instead of master node, rebalance process, client handle duplicate, CRC message, monitoring events, avro protocol

activeMQ, rabbitMQ, zeroMQ, JMS spec

Spark SQL

one-liner: R dataframe like api, Catalyst as query optimizer, nested data model based on Hive, analyze logical plan eagerly, evaluate RDD lazily. Internally, it create a logical data scan operator points to RDD. columnar compression: dict encoding, run-length encoding.

logical optimizer: constant folding, predicate pushdown, projection pruning, null propagation, boolean expr simplification.

physical planning: pipeline projection

codegen: scala quasiquote, AST to code
