Annotation-based 2i with dynamic index names [JIRA: CLIENTS-1017]

[runesl]

The current RiakIndex annotation requires the name to be static like "email" here:

@RiakIndex(name="email")
public Set<String> emailIndx;

We need a way to annotate dynamic indices like:

@RiakIndex
public Map<String, String> references;

Where each key in the Map is a 2i key to index, and each value is the corresponding 2i value.

The old RiakObject based API can do this.
Is this something basho can implement or would you be willing to merge a PR on it?

Hi Rune,

PR's are very welcome! This seems like a small design regression from when we rebuilt the client, so I'd be happy to review and merge anything provided.

Thanks,
Alex

Looks like for this one we'd need to add the appropriate type sniffing code in RiakIndexField and RiakIndexMethod, to detect a map of the proper key type.

Also, I can't find any examples in the 1.4 Client where you can assign the RiakIndex annotation to a Map, do you have any examples you can share / link to?

In http, you can add the same index multiple times when storing.

curl 192.168.99.100:8098/buckets/test/keys/a -XPUT -d 'hello' -H 'X-Riak-Index-myIndex_bin: myvalue1' -H 'X-Riak-Index-myIndex_bin: myvalue2' 
curl 192.168.99.100:8098/buckets/test/index/myIndex_bin/myvalue1
{"keys":["a"]}
curl 192.168.99.100:8098/buckets/test/index/myIndex_bin/myvalue2
{"keys":["a"]}

I'm pretty sure, you can do the same in the old java api.
