A service that maintains a representation of the commit history which allows random access at arbitrary commits.
The Moira's purpose is to maintain an alternate data representation that efficiently allows random access and searching through the properties of a property tree as well as providing queriability on the structure. Such structure is implemented as Versioned B-Trees, where a new commit is materialized as a partial tree, where the unaffected leaves are references to previous trees in time.
These access patterns apply to fetching the state at a point in time or materialized view as well as for a commit.
It is possible to obtain the whole, or many sub-trees from the data representation at any point in time, by specifying filtering by no (all) properties, or specific sub-trees.
It is possible to consume a property tree in the chunks of a specific size, to reduce the access time.
It is possible to consume all data comprised between two paths.
It is possible to perform sorted paging on the direct children as a data source to user interfaces that display data in a paged fashion using the QueryV1 language.
Start the Moira Service using npm start.
Start the Moira Service using node --debug-brk --inspect server.js.
