Efficient processing of queries for historic state changes #20

Closed LinqLover closed 2 years ago

LinqLover commented 2 years ago

Implement a retracing simulator with vector semantics for simultaneous evaluation against all memory states of interest. Allow the client to specify a relevant time window. Provide a search mode with different strategies (forward, backward, binary) with streaming of results.

[dump] Inefficient snippet for testing:

((0 to: self cursor maxTimeIndex) collect: [:time |
    (self cursor object: self selectedContext atTime: time) in: [:ctx |
        [(ctx receiver instVarNamed: 'stream') position]
            on: Error do: #description]])
