I'm not 100% certain but I do not believe that is the case. Part of the reason for structured data is efficient retrieval. I believe the data is read but only the data selected leaves the leveldb backend, unselected data never leaves leveldb so there's no overhead when passing data from level

Re: Object not found after successful PUT on S3 API

Hi Daniel, Riak CS uses multi by default. By default the manifests are stored in leveldb and the blobs/chunks are stored in bitcask. If you're looking to force everything to level you should remove multi and use level as the backend setting. As Luke noted elsewhere, this configuration hasn't

Riak CS stores data chunks in bitcask and the index/metadata file in leveldb. Bitcask, as noted, has no compression. When you force Riak to use level for the data chunks you get compression for that data which may or may not be good for your use case. If it's not good for your use case I

Re: Riak Search Schema Question

Haven't tried it out but should stats be an array? And the query would be something like Stats_name = stat1 and stats_value 1 I think the extractor flattens everything and separates with underscores. -Alexander @siculars http://siculars.posthaven.com Sent from my iRotaryPhone On Oct

Re: Yokozuna Scale

So if we go by your suggestion to set up multiple nodes per physical server - say 6 nodes per - that would be 36 Riak nodes and a corresponding Solr instance - each hosting about 21M documents. Something to be careful with is that as you ramp up the number of Riak nodes on a single physical

Re: Single node, nval = 1

Resizing the ring is a well known issue. A singleton riak with stock 64 ring size should only consume more fd's. What concerns me is the reluctance to change the n_val (replication factor). I was under the impression this was not an issue and could be changed at any time. I thought read

Re: Question about counters

Not that I know of. I believe keys are independent in this regard. Basho is introducing sets in riak 2.0 but I don't think they will bee sorted sets like in redis. -Alexander @siculars http://siculars.posthaven.com Sent from my iRotaryPhone On Jun 29, 2014, at 15:54, Alex De la rosa

Re:

I think the number of characters preceding an asterisk is related to the tokenizer. White space or standard. One of them allows a one character search, the other three I believe. And this worked in riak 1.x. As pointed out elsewhere, the docs you really should be referring to for search

Re: oddness when using java client within storm

I'm not sure what looking up entries... in batches of 100 from Riak devolves into in the java client but riak doesn't have a native multiget. It either does 100 get ops or a [search]mapreduce. That might inform some of your performance issues. -Alexander @siculars
