python-rocksdb python-rocksdb have some problem in time-to-live db

when a rockdb opened by with a time-to-live option,in java is

Options options = new Options().setCreateIfMissing(true);

            options.setKeepLogFileNum(10);
            rawDatadb = TtlDB.open(options, "xxx", 43200, false);

when open using python-rocksdb,the value will print some odd character,it maybe the inner data of time-to-live,when open by python-rocksdb: rocks_db = rocksdb.DB("xxx", opts, read_only=True),even add a ttl to the DB is the same

such as: [{"name":"haha"}]�E�X

@young001

now is : rocksdb_perfconsole_process_db = rocksdb.DB(rocksdb_perfconsole_process_dir, rocksdb.Options(), read_only=True) add ttl to 43200 rocksdb_perfconsole_process_db = rocksdb.DB(rocksdb_perfconsole_process_dir, rocksdb.Options(), read_only=True, ttl=43200) with no luck

Sorry for late reply, Currently python-rocksdb does not support time-to-live api, I will add it.

btw, Can you give me some mini-example databases which can reproduce your problem?

Has time-to-live api been added or not? I can't find any information about it.
