Description

Currently we first write the table and then do register_table.

There are technically 2 other ways to do this:

  1. create_table with empty table, and then write data to it. One issue is that the table shows up before the data is fully written
  2. create_table which creates a running transaction to use, which allows Ray to write data and then commit the transaction at finish time.

Currently a basic namespace probably can only do 1, since the transaction part is not fully flushed out yet.

Research direction

Start at the write_lance create-mode path and the namespace.create_table entry point. Compare the empty-table and transaction-based approaches described in the issue, then clarify which behavior the basic namespace should support and what completion means for data visibility and commit timing.
