Summary0004154: Issue: DataSource supports single index Writes but not multiple index
Description

Some datasources can support index range writes but only if it is 'best effort' or if the range has a single index.

It should be permissible for a server to return BadWriteNotSupported for ranges that it cannot handle while supporting those that it can.

The use cases I see:

1) support single index but not multiple indexes
2) support first dimension but not higher dimensions for matrixes;
3) support multiple dimensions but not indexes into a string/bytestring value.

TagsNo tags attached.

Discussed on call Feb 13th, 2018:

Agreement that best effort is acceptable;

Need spec update to indicate that BadWriteNotSupported could mean the complexity of the IndexRange is too large and less complex IndexRanges may work.

It is also used if writing an IndexRange is not supported for a Node or if only a subset of the possible IndexRange configurations is supported e.g. writing single elements of an array.
