-----------------------------------------
Summary: AST Harry's multi node tests are flakey when multi cell
list happens cross instances
Key: CASSANDRA-20544
URL: https://issues.apache.org/jira/browse/CASSANDRA-20544
Project: Apache Cassandra
Issue Type: Bug
Components: Test/fuzz
Reporter: David Capwell
Assignee: David Capwell
List append relies on TimeUUID.Generator.nextUnixMicro, which relies on the
local clock’s millisecond clock. In jvm-dtest all instances share the same
physical clock, so most of the time time moves forward uniformly, but there is
an edge case when the test “runs too fast” and creates a new TimeUUID within
the same millisecond, when this happens a logically later timeuuid can
happens-before a logically earlier timeuuid!
