Hi all
I am using the orientDB graph database for storing graph from the java
application using *remote* connection and the graph database is *plocal*.
*Version : 1.7.9*
I am using *Blueprints API* (version : 2.6.0) to make queries and adding
vertices, edges in the graph. Each vertex in the graph has around 30 key
value pairs out of which 10 of them are indexed (*SBTREE_MAX_KEY_SIZE :
30000*)
Below is a snapshot of how the graph instance is created ->
*# properties #*
*blueprints.graph=com.tinkerpop.blueprints.impls.orient.OrientGraph*
*blueprints.orientdb.url=remote:127.0.0.1/graph-database
(some remote server address)*
*blueprints.orientdb.username=root*
*blueprints.orientdb.password=AA0256B7269C44BD33118*
*#*
*graph = (OrientGraph) GraphFactory.open(properties);
(com.tinkerpop.blueprints.GraphFactory)*
*graph.createIndex( Key_To_Indexed, Vertex.class);*
Querying is done like
*Iterable<Vertex> vertices =
graph.query().has(key1,value1)....has(key2,value2).hasNot(key).vertices();*
*Iterable<Edge> edges = vertex.getEdges(Direction.OUT,"EdgeType");*
*#Issue 1*
With these configurations, *is the caching enabled* ?? Or something else
has to be done ?? Because the query time is very large and I suspect that I
am doing something wrong.
I just added these two entries in orientdb-server-config.xml ->
*<entry value="true" name="cache.level1.enabled"/><entry value="-1"
name="cache.level1.size" />*
cache.level1.enabledtruecache.level2.enabledfalsecache.level1.size-1
cache.level2.size0profiler.enabledtruelog.console.levelinfolog.file.level
infosbtree.maxKeySize30000
My requirement is such that I need everything to be in memory most of the
time.
*#Issue 2*
I also tried switching to memory database, but it seems that there is no
support for transactional memory graph.
If I just create a memory database on the remote server and point my code
to use that database instead of the plocal one then the code never comes
out of the statement *graph.commit().*
I think this issue was already raised here
