Re: CACHE -> fieldValueCache usage
Hi Yonik, Emir, thanks for your reply. I'm moving a collection from Solr 4.8.1 where there weren't configured docValues for thousands of fields (most of them used for sorting and faceting). In the Solr 4.8.1 I was used to see this fieldValueCache used. On the other hand, in the new version (7.3.1), where docValues are configured everywhere I could the fieldValueCache has all the values 0. Which if I understood correctly, it is good :) Best regards, Vincenzo On Thu, Sep 20, 2018 at 3:39 PM Yonik Seeley wrote: > On Wed, Sep 19, 2018 at 9:44 AM Vincenzo D'Amore > wrote: > > > Looking at Solr Admin Panel I've found the CACHE -> fieldValueCache tab > > where all the values are 0. > > > > [...] > > > > what do you thing, is that normal? > > > Yep, that's completely normal. > That cache is only used by certain operations on multi-valued indexed > fields that don't have docValues.

Yep, that's completely normal. That cache is only used by certain operations on multi-valued indexed fields that don't have docValues. If it ends up not being used, it's fine. -Yonik
Re: CACHE -> fieldValueCache usage
Hi Vincenzo, Are you saying that you used to see some numbers other than 0 and now you see 0? If it is always zero, it means that you are not using features that require uninverted version of field (mainly faceting) or that you have doc values enabled on all fields that are used in such scenario so there is no need to use fieldValueCache which is recommended. FieldValueCache is defined by default so that’s why it is not defined in solr.xml, but you can override defaults.

CACHE -> fieldValueCache usage
Hi all, sorry if I bothered you all but in these days I'm just struggling what's going on with my production servers... Looking at Solr Admin Panel I've found the CACHE -> fieldValueCache tab where all the values are 0. class:org.apache.solr.search.FastLRUCache description:Concurrent LRU Cache(maxSize=1, initialSize=10, minSize=9000, acceptableSize=9500, cleanupThread=false) stats: CACHE.searcher.fieldValueCache.cumulative_evictions:0 CACHE.searcher.fieldValueCache.cumulative_hitratio:0 CACHE.searcher.fieldValueCache.cumulative_hits:0 CACHE.searcher.fieldValueCache.cumulative_inserts:0 CACHE.searcher.fieldValueCache.cumulative_lookups:0 CACHE.searcher.fieldValueCache.evictions:0 CACHE.searcher.fieldValueCache.hitratio:0 CACHE.searcher.fieldValueCache.hits:0 CACHE.searcher.fieldValueCache.inserts:0 CACHE.searcher.fieldValueCache.lookups:0 CACHE.searcher.fieldValueCache.size:0 CACHE.searcher.fieldValueCache.warmupTime:0 what do you thing, is that normal? Given that this stats comes from a production server I suppose to have some number here and looking at solrconfig.xml I don't see any configuration regarding the fieldValueCache. Don't should I see something here? Cheers, Vincenzo -- Vincenzo D'Amore
