Re: Graph Database with Ignite? Search like Elastic search/Apache Solr with Ignite?
Thanks! You will think graph (edges and vertex), graph traversal, could be added to ignite. Actually that was my next question, is it possible to add a search (like elastic search or apache solr) on top of all those ignite tables?

This does normally not make sense because most graph databases keep the graph structure (not necessarily the vertex details, but vertexes and edges ) in-memory. As far as I know, Ignite does not provide graph data structures such as adjacency matrix/list. If you have a very huge graph of which the structure does not fit into memory then you can work with a distributed graph, such as JanusGraph. It has various plugable backends, such as hbase for the graph and solr for indexing vertexes. Maybe someone will write an Ignite backend. Of course you could try to run hbase on IGFS , but that would be a little bit far fetched. On 30.

Graph Database with Ignite?

Re: Ignite with dBeaver
Hello, I’m evaluating ignite and I need a free tool to see the tables and cache content. What is the best free tool to query the cache via SQL? Something like dBeaver or anything else that works.
