A shell for the
system
table provider was added to theQueryExecutorImpl
which currently does not do anything, but will enable us to tie the different system table providers into it. For example, see the follow up PR that adds thesystem.queries
table: #24992One notable change in this PR was the elevation of the
QueryLog
from theDatabase
, i.e., namespace provider, to theQueryExecutorImpl
, so that it lives across queries.Closes #24986
