Abstract
Structures and processes for garbage collection of search trees under Multi-Version Concurrency Control (MVCC). Such search trees may be used to store data within a distributed storage system. A process detects live search tree elements using tracing and then identify storage chunks having no live elements as garbage to be reclaimed. The process can be paused and resumed to reduce impact on other system processing.
