Rehashing and state transfer to use digesting

    XMLWordPrintable

Details

    Description

      Rather than pushing entire state to new joiners, a mechanism of digests should be used to minimise network transfers. For example, Merkle trees can be used to determine which entries are out of date and need pushing, in the case of nodes that persist to a local cache store, and is restarted but still has access to some state on disk.

      This would require versioned entries though.

          • Blocker - To be worked above all other priorities. This term is chosen when the severity of the issue is very high, has no workaround, or the effort for the change is comparatively low. Issues that may be very publicly visible and could generate significant media attention may also drive a higher priority.

          Bug - A problem that impairs or prevents the functions of the product. ISPN-3431 Lost version info during state transfer causes overwrite of newer data that joining node has read from store

          Enhancement - An enhancement to or refactoring of existing functionality that is not configurable by an end user (typically a change made by an internal team that affects users) ISPN-8412 Conflict resolution should utilise Merkle trees to improve performance

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
