LSM Management and Using LSM Immutability for Data Virtualization (Vaibhav Arora)

Aug 20, 2024

LSM (Log-Structured Merge) trees are now the bedrock of many storage engines and datastores like RocksDB, HBase, Cassandra etc. They provide the ability to avoid random-writes, and provide immutability. Data is organized in multiple-levels that are exponentially increasing in size. Each data mutation writes a new version of an object, and background processes named merge/compaction continuously remove the unused versions, while moving the data across the layers of the LSM tree and maintain its shape. This talk will describe how Read More
