Power of the Log:LSM & Append Only Data Structures



Ben Stopford talks about the beauty of sequential access and append only data structures, in the context of a little known paper entitled “Log Structured Merge Trees”. LSM describes a counter intuitive approach to storing and accessing data in a sequential fashion.


Ben Stopford is an engineer working on the Core Apache Kafka at Confluent Inc (the company behind Apache Kafka). He's worked with distributed data infrastructure for over a decade, switching between engineering products and helping companies use them. Before Confluent he designed the central data infrastructure for a large investment bank.
