byronellis opened a new pull request, #2328:
URL: https://github.com/apache/polaris/pull/2328
This is the first commit in a series that implements a Spanner Persistence
backend for Polaris. It is largely modeled on the JDBC implementation though it
takes advantage of Spanner-specific features such as nested tables.
In this design the parent table is Realm with all other tables nested within
that parent table.
In this initial PR we commit the basic classes needed to manage the Spanner
connection lifecycle as well as the Realm model as Realm bootstrapping is part
of Lifecycle management. This was cleaner than making it part of the
persistence implementation and has the added benefit of allowing for a cleaner
initial PR.
