 Description   

Once lock-free reads project is complete, we will need to implement a number of changes to support lock-free reads in SBE. This ticket is created to track this work.

Comment by David Storch [ 18/Feb/21 ]

The SBE engine is already running and being tested under lock free reads, as lock free reads are enabled by default. Therefore, no further work is needed for this ticket and I am closing it as "Gone away".

Note, however, that there are a handful of tasks related to SBE's use of the db_raii helpers and SBE's yielding implementation that need to be resolved: see SERVER-50710, SERVER-54624, and SERVER-49385.
