Abstract: Systems and methods are provided for conducting continuous changelog-based replication of modifications made to a file system to a target storage system. An export system can monitor a changelog on a file system to detect changes made to the file system. The exporter system can further filter and reformat the changes for replication to the target storage system by storing the changes in a pending changes data store. To reduce duplicative traffic, the export system can store changes for a configurable delay period, writing all pending changes to a file system object after the delay while aggregating and deduplicating the changes, thus improving performance relative to immediate replication.

Abstract: During a throttling parameter determination, a throttling manager of a file storage service transmits a maximum throughput allotment to an access node of the service. The allotment is based at least in part on the estimated size of a file system instance. The access node assigns respective portions of the allotment to individual ones of a set of persistent client connections classified as sustainable-demand connections, such that the connections are able to sustain their throughputs for a time period. The remainder of the allotment is distributed among one or more high-demand persistent client connections. The access node enforces the throughput limits assigned to the connections.
