Abstract
Columnar storage provides many performance and space saving benefits for analytic workloads, but previous mechanisms for handling single row update transactions in column stores suffer from poor performance. A columnar data layout facilitates both low-latency random access capabilities together with high-throughput analytical access capabilities, simplifying Hadoop architectures for use cases involving real-time data. In disclosed embodiments, systems may perform read and scan features through which users may have consistent reads of the columnar storage at any given point in time. These scans (e.g., snapshots) allow for analytics to be performed on the data, consistent backups of the data, for incremental backups, perform cross-cluster synchronization, and/or for offline audit analysis.
