Where does JanusGraph Stores Indexes in ElasticSearch


"kri...@gmail.com" <krishna...@...>
 

Hi Folks,


Currently i am using JanusGraph with Cassandra(cql) backend along with ElasticSearch for indexing. we have created few janusgraph vertex-centric indexes through janusgraph. Queries of janusgraph is working fine. when i try to get indexes from ElasticSearch through below query i cannot found the indexes created for janusgraph.


how can we find the janus graph indexes data in ElasticSearch?
where the indexes data is stored in ElasticSearch?


Thanks&Regards

Hi Krishna,

The documentation is not conclusive about this, but I strongly suspect that the vertex-centric indices do not use the indexing backend. That means that they use the tables in the storage backend, like for the composite indices.

HI Marc

Thanks for your response. Is elastic search only used for mixed indexes?. if we only build composite indexes in our use can we neglect giving elasticsearch config properties in building graph through graph factory?

Hi Krishna,

That is right. The mixed index is for non-equality matches.

Hi,

ElasticSearch is used for mixed indexes only. If you don't use mixed indexes, you don't need ElasticSearch.
All other indexes are stored in a storage backend you are using (Cassandra, HBase, etc.).

Best regards,
Oleksandr
