---------------------------------------
Assignee: Ivan Pavlukhin
> Update counters mismatch after loading data via DataStreamer into
> MVCC-enabled caches
> -------------------------------------------------------------------------------------
>
> Key: IGNITE-11242
> URL: https://issues.apache.org/jira/browse/IGNITE-11242
> Project: Ignite
> Issue Type: Bug
> Components: mvcc, streaming
> Affects Versions: 2.7
> Reporter: Ivan Artukhov
> Assignee: Ivan Pavlukhin
> Priority: Critical
>
> *Steps:*
> Start 1000 caches in 100 cache groups. Caches configuration:
> {code:xml}
> <property name="atomicityMode"
> value="TRANSACTIONAL_SNAPSHOT"/>
> <property name="backups" value="2"/>
> <property name="cacheMode" value="PARTITIONED"/>
> <property name="writeSynchronizationMode"
> value="FULL_SYNC"/>
> <property name="partitionLossPolicy"
> value="READ_WRITE_SAFE"/>
> {code}
> Preload 10000 keys into each cache using DataStreamer
> Run *VerifyBackupPartitionsTaskV2* to check partition inconsistencies between
> hashes or update counters
> *Expected:*
> There are no differences between primary and backup partitions
> *Actual:*
> Two or three *backup* partitions in each cache group have update counters
> which differ from corresponding primary partitions. E.g.:
> {code}
> [2019-02-07 11:04:23,286][INFO ][Task-threadNum-0] Conflict partition:
> PartitionKeyV2 [grpId=-1093321804, grpName=cache_group_100, partId=261]
> [2019-02-07 11:04:23,286][INFO ][Task-threadNum-0] Partition instances:
> [PartitionHashRecordV2 [isPrimary=true, consistentId=id-0, updateCntr=100,
> size=100, partHash=665729765], PartitionHashRecordV2 [isPrimary=false,
> consistentId=id-1, updateCntr=91, size=100, partHash=665729765],
> PartitionHashRecordV2 [isPrimary=false, consistentId=id-2, updateCntr=100,
> size=100, partHash=665729765]]
> {code}
