-------------------------------------
Summary: Clean up prune state when invalid list is empty
Key: TEPHRA-225
URL: https://issues.apache.org/jira/browse/TEPHRA-225
Project: Tephra
Issue Type: Improvement
Reporter: Poorna Chandra
Assignee: Poorna Chandra
Fix For: 0.12.0-incubating
Invalid list can be empty in two cases - when transaction manager just starts
up, or when all invalid transaction ids get pruned. When a prune run starts
with empty invalid list, then we can clean up prune state using the inactive
transaction bound, since there can be no data from an invalid transaction
smaller than the inactive transaction bound in the store. Hence we don't need
any prune state that is stored earlier than the inactive transaction bound.
