Abstract
A distributed logging system for nodes in a cluster network system. A distributed log has a shared storage architecture and provides durability by maintaining multiple copies of the log data, and availability is facilitated through a sealing protocol that ensures that system failure results in reconfiguration with a new node. Logs generated by nodes are stored in a shared log that is segmented based on the logs and respective entries. A metastore maintained in one node contains a mapping of the logs with respective storage locations. The system comprises fast Non-Volatile RAM (NVRAM) to store the log data and slower tiered storage to store log data for segments that are full or sealed. Segments are migrated to the tiered storage based on a time or space usage parameter.
