> Key: IGNITE-5590
> URL: https://issues.apache.org/jira/browse/IGNITE-5590
> Project: Ignite
> Issue Type: Bug
> Affects Versions: 2.1
> Reporter: Ksenia Rybakova
> Priority: Minor
> Attachments: ignite-base-load-config.xml, run-load.properties,
> run-load.xml
>
>
> The following experiment was done to compare logical vs physical caches witn
> PDS:
> - CacheRandomOperation benchmark was used to load data into caches
> - Number of loaded entries 10M per cache
> - All caches are atomic: 10 logical caches in 1 group vs 10 physical caches
> - walHistorySize =2
> - One default memory policy, memory config is default as well
> Configs are attached.
> ||10 logical caches in 1 group|| 10 physical caches ||Comments||
> ||Total size of work/db/127_0_0_1*| |Among all hosts|
> |23.6G|28.6G|Mainly because total size of partitions files (part-xxxx.bin) in
> "physical" case is bigger. In "phisical" case index.bin is one per cache
> while in "logical" case is one per group, but it's size is 16Kb so it doesn't
> make any difference.|
> ||Total size of work/db/wal/archive| |Among all hosts|
> |86.7G|63.6G|In "physical" case archive has more files.|
> ||Total size of work/db/wal/127_0_0_1*| |Among all hosts|
> |7.6G|7.6G| |
> The size difference should be investigated, currently reason is unclear.
