-----------------------------------------
Summary: Accord Route Index does not filter based off txn_id range
which causes segments which can't contain the data to be queried
Key: CASSANDRA-20772
URL: https://issues.apache.org/jira/browse/CASSANDRA-20772
Project: Apache Cassandra
Issue Type: Improvement
Components: Accord
Reporter: David Capwell
Assignee: David Capwell
When the accord route index searches for range transactions we pass in a
min/max timestamp range to search for, but this gets ignored. The issue with
ignoring it is that we will do unneeded disk searches as we will include
segments that don’t have data for the range and must get filtered out after the
read.
We should respect the txn_id passed in to limit the segments to only the ones
that “could” match.
