-------------------------------------
Summary: Support a process to transition a table from
transactional to non transactional
Key: PHOENIX-2439
URL: https://issues.apache.org/jira/browse/PHOENIX-2439
Project: Phoenix
Issue Type: Improvement
Reporter: James Taylor
Phoenix supports converting a non transactional table to become transactional
through the ALTER TABLE command, however the reverse is not possible. To
support this, Phoenix would need to re-write the transactional rows to have
wall-clock timestamps, taking into account the Tephra delete markers. One
potential way would be to allow the ALTER TABLE command to be run, but not
rewrite the data until a major compaction occurs. Prior to that, we'd need to
multiply the timestamps by 1000000 and continue to apply the part of the Tephra
filter that handles the Tephra delete markers application.
