> ---------------------------------------------------------------------------
>
> Key: ATLAS-3254
> URL: https://issues.apache.org/jira/browse/ATLAS-3254
> Project: Atlas
> Issue Type: Bug
> Components: atlas-core, atlas-webui
> Affects Versions: 1.0.0, 2.0.0
> Reporter: Adam Rempter
> Assignee: Mayank Jain
> Priority: Major
> Labels: performance
> Attachments: Screenshot 2019-11-28 at 21.18.44.png, entity_auto_create.sh, example_create_entities.json, rest_entity_get_pseudodir.json

> We use “aws_s3_pseudo_dir” type from 3020-aws_s3_typedefs.json model.
> It has following property:
> "name": "s3Objects",
> "typeName": "array<aws_s3_object>"
>
> Now in AWS buckets you can have thousands of objects. This causes that s3Objects array grows quite quickly, causing aws_s3_pseudo_dir entity Json to rich easly few MBs.
>
> Then we start seeing problems like:
> * UI is dying on displaying entity properties or lineage
> * Error in logs: audit record too long: entityType=aws_s3_pseudo_dir, guid=24398271-6ba0-4db5-adfa-38e432dc55ce, size=1053931; maxSize=1048576. entity attribute values not stored in audit (EntityAuditListenerV2:234)
> * Some errors with write to HBase (java.lang.IllegalArgumentException: KeyValue size too large, as workaround we set hbase.client.keyvalue.maxsize param to 0)
> * kafka consumer errors (we can of course set some parameters on consumer, but I think it is just workaround)
> …
> Exception in NotificationHookConsumer (NotificationHookConsumer:332)
> org.apache.kafka.clients.consumer.CommitFailedException: Commit cannot be completed since the group has already rebalanced and assigned the partitions to another member. This means that the time between subsequen
> t calls to poll() was longer than the configured max.poll.interval.ms, which typically implies that the poll loop is spending too much time message processing. You can address this either by increasing the sessio
> n timeout or by reducing the maximum size of batches returned in poll() with max.poll.records.
> …
> Specifying pseudo_dir is required for s3objects:
> name": "pseudoDirectory",
> "typeName": "aws_s3_pseudo_dir",
> "cardinality": "SINGLE",
> "isIndexable": false,
> *"isOptional": false,*
> "isUnique": false,
