Hybrid Garbage Collection for Multi-Version Concurrency Control in SAP HANA
2016
Proceedings of the 2016 International Conference on Management of Data - SIGMOD '16
While multi-version concurrency control (MVCC) supports fast and robust performance in in-memory, relational databases, it has the potential problem of a growing number of versions over time due to obsolete versions. Although a few TB of main memory is available for enterprise machines, the memory resource should be used carefully for economic and practical reasons. Thus, in order to maintain the necessary number of versions in MVCC, versions which will no longer be used need to be deleted.
