--------------------------------------
Summary: Creating a SASI index after creating an SAI index breaks
secondary indexing
Key: CASSANDRA-18939
URL: https://issues.apache.org/jira/browse/CASSANDRA-18939
Project: Cassandra
Issue Type: Bug
Components: Feature/2i Index
Reporter: Jon Haddad
In the 5.0 branch, HEAD is e45c1092f91edd63591f562b2120ea6a5fd3edd5, I was able
to break secondary indexes by doing the following:
{code}
cqlsh -e "create KEYSPACE test WITH replication = {'class': 'SimpleStrategy',
'replication_factor': 1};"
cqlsh -e "create table test.blah (id int primary key, val text);"
cqlsh -e "create INDEX on test.blah (val) using 'sai';"
bin/nodetool flush
❯ cqlsh -e "SELECT * from test.blah WHERE val = 'something';"
id | val
----+-----
(0 rows)
cqlsh -e "create custom INDEX on test.blah (val) using
'org.apache.cassandra.index.sasi.SASIIndex';"
Warnings :
SASI indexes are experimental and are not recommended for production use.
cqlsh -e "SELECT * from test.blah WHERE val = 'something';"
<stdin>:1:ReadFailure: Error from server: code=1300 [Replica(s) failed to
execute read] message="Operation failed - received 0 responses and 1 failures:
UNKNOWN from localhost/127.0.0.1:7000" info={'consistency': 'ONE',
'required_responses': 1, 'received_responses': 0, 'failures': 1,
'error_code_map': {'127.0.0.1': '0x0000'}}
{code}
Server throws an exception:

Dropping the SASI index restores correct behavior.
