[[ neoSemantics delete issue ]]

When deleting large amounts of data with neoSemantics, the following error occurs.

com.google.common.cache.CacheLoader$InvalidCacheLoadException: CacheLoader returned null for key http://kisti.re.kr/resource/BJD_1111010700. at com.google.common.cache.LocalCache$Segment.getAndRecordStats(LocalCache.java:2375) at com.google.common.cache.LocalCache$Segment.loadSync(LocalCache.java:2337) at com.google.common.cache.LocalCache$Segment.lockedGetOrLoad(LocalCache.java:2295) at com.google.common.cache.LocalCache$Segment.get(LocalCache.java:2208) at com.google.common.cache.LocalCache.get(LocalCache.java:4053)

CacheLoader says that it cannot find a key and returns null, but when I search for that key in the store, the data exists.

Hi, would it be possible to get some context, please? Steps to reproduce the issue would be ideal.

Thanks,

JB.

Hi, I first import about 20G rdf file in neo4j using n10s.rdf.import.fetch method. Then, the imported data is deleted using the n10s.rdf.delete.fetch method. However, InvalidCacheLoadException occurred in the process of deletion.

When I test in the same process with a small file, rdf data is imported and deleted successfully.

Do you mean you try to delete the whole file after loading it? What’s the status of the DB after the failure? Are some triples deleted? Or none? Any additional info in the logs? No stack trace? Does this happen early in the process or after a while? Is the 20GB RDF file public so we can try to reproduce?

Thanks,

JB

• Do you mean you try to delete the whole file after loading it? : yes, I delete the whole file after loading it.
• What’s the status of the DB after the failure? Are some triples deleted? Or none? : some triples deleted. -Does this happen early in the process or after a while? : this happen after a while. -Is the 20GB RDF file public so we can try to reproduce? :* It's not a public file, so I need to discuss it for sharing.*

I'll try it but it would be great if you could share your file. Let me know when you find out. You can send it privately to jesus at neo4j dot com

sorry for the late contact. I received a notice that I can share the 20GB RDF file. How do I share this file?

That's great news. Maybe you can put it somewhere I can download it from and then send me the access details and credentials to jesus at neo4j dot com ?

Thanks!

What does it mean to send credentials to jesus at neo4j dot com.

send me by email the location and user/pwd if needed to download the file that's my email address. Just replace at=@ dot=. and you got it.

Thanks!

JB.

I send the file using the email [email protected].
