> # Couchbase translator supports only subset of supported datatypes in Teiid:
> ??All supported type in a Couchbase JSON item: null, String, Integer, Long, Double, BigInteger, BigDecimal, JsonObject, JsonArray??
> #* this is too restrictive, why not float? time/date/timestamp? And let the translator to handle conversion in both directions.
> # Couchbase leaves out silently the columns with unsupported data types in INSERTs.
> #* See the example in bottom of description.
> # documentID is (in code) considered String. This is too restrictive. In the code there might be String.valueOf() instead of (String) cast (N1QLUpdateVisitor.java:139). It would help users to use their primary keys (from existing datasets) as document ids in couchbase.
> Example:
> For a source model DDL:
> {code:sql|title=DDL}
> CREATE FOREIGN TABLE SmallA (
>         documentID string PRIMARY KEY,
>         type string OPTIONS (NAMEINSOURCE '`type`'),
>         FloatNum float OPTIONS (NAMEINSOURCE '`FloatNum`'),
>         BigIntegerValue biginteger OPTIONS (NAMEINSOURCE '`BigIntegerValue`'),
>         StringKey string OPTIONS (NAMEINSOURCE '`StringKey`'),
>         CharValue string OPTIONS (NAMEINSOURCE '`CharValue`'),
>         LongNum long OPTIONS (NAMEINSOURCE '`LongNum`'),
>         DoubleNum double OPTIONS (NAMEINSOURCE '`DoubleNum`'),
>         ObjectValue string OPTIONS (NAMEINSOURCE '`ObjectValue`'),
>         ShortValue integer OPTIONS (NAMEINSOURCE '`ShortValue`'),
>         BigDecimalValue bigdecimal OPTIONS (NAMEINSOURCE '`BigDecimalValue`'),
>         DateValue string OPTIONS (NAMEINSOURCE '`DateValue`'),
>         BooleanValue boolean OPTIONS (NAMEINSOURCE '`BooleanValue`'),
>         TimestampValue string OPTIONS (NAMEINSOURCE '`TimestampValue`'),
>         ByteNum integer OPTIONS (NAMEINSOURCE '`ByteNum`'),
>         StringNum string OPTIONS (NAMEINSOURCE '`StringNum`'),
>         TimeValue string OPTIONS (NAMEINSOURCE '`TimeValue`'),
>         IntNum integer OPTIONS (NAMEINSOURCE '`IntNum`')
>       ) OPTIONS (NAMEINSOURCE '`dvqe_crud`', UPDATABLE TRUE, "teiid_couchbase:ISARRAYTABLE" 'false', "teiid_couchbase:NAMEDTYPEPAIR" '`type`:''nullSmallA''');
