This commit is part of a two-part change in order to add the table &
namespace IDs to the write buffer wire format. This commit forms the
first half; changing the producer to send the IDs.
In this commit the new ID values are never read on the consumer side,
ensuring there is no consumer dependency on them. This ensures they
remain operational during a rollout, where the consumer may be updated
to the latest code dependent on the IDs before the producer is updated
to send them. This also ensures we have a window of time where where the
consumers can be rolled back after being updated, and still handle
replaying messages in Kafka.
Changes the DmlWrite type to require a PartitionKey be specified,
instead of accepting an Option.
This requirement was already in place - the write buffer upheld an
invariant that all writes contained a partition key value (was not
"None") or it panicked at runtime when attempting to enqueue the write.
It is now possible to encode this invariant in the type system, which is
what this change does.
* feat: Add db_name/namespace to DmlWrite and DmlDelete
This is required for the new ingester to be able to work with the write buffer. The protobuf that gets serialized over Kafka already includes the database name, it just wasn't getting carried through to the marshaled Dml operation.
* fix: database != namespace, propagation through write buffer
