> 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
