------------------------------------------

             Summary: SSTableWriter output discrepancy
                 Key: CASSANDRA-11646
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-11646
             Project: Cassandra
          Issue Type: Bug
            Reporter: T Jake Luciani
             Fix For: 3.6


Since CASSANDRA-10624 there is a non-trivial difference in the size of the 
output in CQLSSTableWriter.

I've written the following code:

{code}
 String KS = "cql_keyspace";
        String TABLE = "table1";

        File tempdir = Files.createTempDir();
        File dataDir = new File(tempdir.getAbsolutePath() + File.separator + KS 
+ File.separator + TABLE);
        assert dataDir.mkdirs();

        String schema = "CREATE TABLE cql_keyspace.table1 ("
                        + "  k int PRIMARY KEY,"
                        + "  v1 text,"
                        + "  v2 int"
                        + ");";// with compression = {};";
        String insert = "INSERT INTO cql_keyspace.table1 (k, v1, v2) VALUES (?, 
?, ?)";
        CQLSSTableWriter writer = CQLSSTableWriter.builder()
                                                  .sorted()
                                                  .inDirectory(dataDir)
                                                  .forTable(schema)
                                                  .using(insert).build();


        for (int i = 0; i < 10000000; i++)
            writer.addRow(i, "test1", 24);

        writer.close();
{code}

Pre CASSANDRA-10624 the data file is ~63MB. Post it's ~69MB
