I have verified this issue to be fixed in 3.6 and 3.7. 
And the issue mentioned on this thread is fixed as well.

Joel,

If we look at the schema carefully:
CREATE TABLE test0 (
    pk int,
    a int,
    b text,
    s text static,
    PRIMARY KEY (pk, a)
);
and filtering is performed on clustering column a and its not a static column:
select * from test0 where pk=0 and a=2;

It doesn't seem to be an exact duplicate - CASSANDRA-11513 relies on you selecting a static column, which you weren't doing in the reported issue. That said, I haven't looked too closely.

I can reproduce CASSANDRA-11513 locally on 3.5, possible duplicate.

There's some precedent for similar issues with static columns in 3.5 with https://issues.apache.org/jira/browse/CASSANDRA-11513 - a deterministic (or somewhat deterministic) path for reproduction would help narrow the issue down farther. I've played around locally with similar schemas (sans the stratio indices) and couldn't reproduce the issue.

Jira CASSANDRA-12003 Has been created for the same.

Hi Tyler,

This issue is mainly visible for tables having static columns, still investigating.
We will try to test after removing lucene index but I don’t think this plug-in could led to change in behaviour of cassandra write to table's memtable.

Is 'id' your partition key? I'm not familiar with the stratio indexes, but it looks like the primary key columns are both indexed.  Perhaps this is related?

After further debug, this issue is found in in-memory memtable as doing nodetool flush + compact resolve the issue. And there is no batch write used for this table which is showing issue.

No, all rows were not the same.
Querying only on the partition key gives 20 rows.
In the erroneous result, while querying on partition key and clustering key, we got 16 of those 20 rows.

And for "tombstone_threshold" there isn't any entry at column family level.

Thanks,
