Timeline

 

  • Alex had been assigned this work but was not able to complete it so it moved to Lukasz

Discussion of process

  • LMDB blocks threads, which can lead to run-time errors

  • Proposed solution

    • switch execution context to a scheduler capable of managing fibers

    • use this solution for RSpace and Casper

Tools

  • Plan to use Tagless Final (Monix Task?), which supports fiber management - finer grained thread management

  • Pair programming Dom, Lukasz, Sebastian, Pavel to prove out

Action items
