Hi I would like to know how to create MapReduce view using buitin “_stat” function. I don’t see it any where in the couchbase lite sdks.
This is my view:
[[_database viewNamed: @“viewEventIndex”] setMapBlock: MAPBLOCK({
if ([doc[@"Type"] isEqualToString:@"Event"])
emit(doc[@"UserID"], doc[@"EventID"]);
}) reduceBlock: REDUCEBLOCK({
@(values.count);
return // ** what is the stat function? **
);
}) version: @“1.0”];
Thank you.
Hello @woody_12,
Have you taken a look into…
CBLReduceBlock stats = CBLGetReduceFunc(@“stats”)
and having your setMap: then with…reduce:stats
[[_database viewNamed: @"viewEventIndex"] setMapBlock: MAPBLOCK({
if ([doc[@"Type"] isEqualToString:@"Event"])
emit(doc[@"UserID"], doc[@"EventID"]);
}) reduceBlock:stats ];
Does that give you the stats logic?
Hi Sweetiewill,
I think the method CBLGetReduceFun() is removed. I see from the class reference that it resides in “CBLReduceFuncs.h” but that header no longer in the latest SDK.
Thanks
