Storing views results within Couchbase, and using them again

Couchbase Server
1

Hi all,

I really need some urgent help with this.

I need to apply views on some documents in Couchbase and I need to use these results to pass them to memcached (the one inside Couchbase) and I’m not sure how to do this.

I couldn’t find how to store views results inside Couchbase, it seems that they can only be used as a query, but may be I’m wrong.

and how can I export these results to Memecached, this is really important to know.

Any help is very much appreciated.

Thanks,

Hello,

So what you have to do is, once the view is created:

  • Call the views with the parameters/queries you want to cache/ (this needs to be done from your application)

  • then just take the result of your query call, and store it into Couchbase with a TTL.

Something that looks like (using Java):

Object o = cb.get(“query-result-001”);
if (o == null) {
View view = cb.getView(“brewery”, “by_name”);
Query query = new Query();
query.setLimit(100);
Map<String, String> result = new HashMap<String,String>();
ViewResponse viewResponse = cb.query(view, query);
for (ViewRow row : viewResponse) {
result.put(row.getId(), row.getKey());
}
cb.set(“query-result-001”, 10, json.toJson(result));
}
// deal with the result

Is this the type of information you are looking for?
