--------------------------------------
Summary: Data Inserted Immediately After Secondary Index Creation
is not Indexed
Key: CASSANDRA-6924
URL: https://issues.apache.org/jira/browse/CASSANDRA-6924
Project: Cassandra
Issue Type: Bug
Components: Core
Reporter: Tyler Hobbs
Fix For: 1.2.16
The head of the cassandra-1.2 branch (currently 1.2.16-tentative) contains a
regression from 1.2.15. Data that is inserted immediately after secondary
index creation may never get indexed.
You can reproduce the issue with a [pycassa integration
test|https://github.com/pycassa/pycassa/blob/master/tests/test_autopacking.py#L793]
by running:
{noformat}
nosetests tests/test_autopacking.py:TestKeyValidators.test_get_indexed_slices
{noformat}
from the pycassa directory.
The operation order goes like this:
# create CF
# create secondary index
# insert data
# query secondary index
If a short sleep is added in between steps 2 and 3, the data gets indexed and
the query is successful.
If a sleep is only added in between steps 3 and 4, some of the data is never
indexed and the query will return incomplete results. This appears to be the
case even if the sleep is relatively long (30s), which makes me think the data
may never get indexed.
