> In the module of DeltaStreamer, Option of QUERY_TYPE_OPT_KEY and BEGIN_INSTANTTIME_OPT_KEY is used to tell the DeltaStreamer to query data after the specific time.
> Such as method is not very convenient for user. So if we can implement the function that User can set BEGIN_INSTANTTIME_OPT_KEY and BEGIN_INSTANTTIME_OPT_KEY at the sql, which is not only very convinient for user, also very a elegant implementation.
