------------------------------------------
Summary: Column can expire while lazy compacting it...
Key: CASSANDRA-5799
URL: https://issues.apache.org/jira/browse/CASSANDRA-5799
Project: Cassandra
Issue Type: Bug
Affects Versions: 1.2.7
Reporter: Fabien Rousseau
Using TTL + range tombstones can lead to failure while lazy compacting rows.
Scenario to reproduce :
- create an SSTable with one row and some columns and a TTL of 8 seconds
- wait one second
- create a second SSTable with the same rowkey as above, and add a range
tombstone
- start the first pass of the lazy compaction before the columns with TTL are
expired
- wait 10 seconds (enough for columns with TTL to expire)
- continue lazy expiration
- the following assertion will fail :
[junit] junit.framework.AssertionFailedError: originally calculated column
size of 1379 but now it is 1082
[junit] at
org.apache.cassandra.db.compaction.LazilyCompactedRow.write(LazilyCompactedRow.java:150)
