SolrIndex client clean all collections when droping a graph

[benjamincoven]

Actually droping a graph in Gremlin console empties all the collections of Solr of the others graphs.

• Storage Backend: inmemory
• Mixed Index Backend: solr
• Link to discussed bug: lfai
• Expected Behavior: Droping a graph cleans/removes only its corresponding index leaving the others unchanged
• Current Behavior: Droping a graph cleans all solr/zookeeper collections
• Steps to Reproduce: Create a graph with a solr index with data. Create a second graph, drop it and check that the solr index of the first graph is now empty

Responsible code maybe the method clearStorage from SolrIndex.java line 971

We found a workaround by removing solr from the graph config before dropping it:

map = new HashMap(); map.put("index.<graph config namespace>.backend", ""); ConfiguredGraphFactory.updateConfiguration("<graph name>",new MapConfiguration(map));

Hi @benjamincoven I had faced the same issue when using Elasticsearch mixed index backend, your workaround is neat and works well, thanks!
