It's unclear how to insert binary data using this driver. http://rethinkdb.com/api/javascript/binary/

Hello Daniel!

I'm using version 0.6

If value in Map is null it can not be inserted:

example:

Map a = new HashMap();
a.put("b", null);
r.run(r.db("myDb").table("myTable").insert(a));

throws:

java.lang.NullPointerException

Thanks for great work!

I have seen that when we insert simple json, it works, but when we use optional parameter in json like:
table.insert(json | [json][, {durability: "hard", returnVals: false, upsert: false}]) it produce error:
r_str: "Expected 2 argument(s) but found 3."
the second parameter is also in java Hashmap

Thanks.

I have problem to convert value from get_all(array) in string(as json) or Map.

 RqlCursor cursor = r.db("test").table("x").get_all(arraylist)

when I try to fetch like

for(RqlObject o : cursor) {
        if (o instanceof java.util.List<?>) {
            List<Object> list = o.getList();
          }else if (o instanceof ListIterator<?>) {
            List<Object> list = o.getList();
          }else {
              java.util.Map<String, Object> map = o.getMap();
            }
}

None of other instances than Map catches above condition and generated error java.util.ArrayList cannot be cast to java.util.Map
How can I get this Object in map or array of list map or even in json formatted string.

Environment:

1. OpenJDK 1.7
2. RethinkDB java driver 0.3
3. Guava 17.0

Run following code:

  RethinkDB rd=RethinkDB.r;
        RethinkDBConnection con = rd.connect("172.16.140.63");
        Map map1=new HashMap();
        map1.put("id", new UUID(221L, 2L).toString());
        Map map2=new HashMap();
        map2.put("ccc", "ddd");

        ArrayList<Map> originalList = Lists.newArrayList(map2,map2);
        Collection<Map> convertedList=Collections2.transform(originalList, new Function<Map, Map>(){

            @Override
            public Map apply(Map f) {
                return f;
            }

        });

        map1.put("innerListOfMap", convertedList);

        rd.table("test").insert(map1,Durability.soft, Boolean.FALSE, Boolean.TRUE).run(con);
        con.close();

Result: Will throw exception:
com.rethinkdb.RethinkDBException: Unknown Value can't create datatype for : class java.util.HashMap

Expected: I think should not throw exceptions since com.google.common.collect.Collections2$TransformedCollection -regular collection (extends java.util.AbstractCollection)

Doesn't it make sense to add them since they'll rarely change and then you won't force users to install an additional toolchain?

I'm seeing a result with status SUCCESS_SEQUENCE being returned by the get_all operation, causing the cursor to prematurely return with an empty result set. Let me know if you can't reproduce this. This is a very preliminary finding on my part.

Sorry Again I am confused because there is no any documentation, I did not find anything, is it already possible to use Lambda function?

Hi @dkhenry,

Could you clarify what you mean in the readme "status" subheading by, "API version 1.0 and 2.0"? I cannot find any information about what the (I assume, RethinkDB) API version corresponds to.

It's not clear to me, given your comment in parentheses, "RethinkDB 1.5 .. 1.11", whether this driver is compatible with RethinkDB v2.0.x.

Thanks in advance for your time.
