> 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';"
