Neo4j embedded with high availability -
i used spring data neo4j embedded 1 of poc. works blazing fast on single machine. before going production, wanted separate database application server. configured 3 neo4j server instances , ha proxy , used spring data neo4j rest connect. speed worst. each query takes more 30 seconds execute.
i thinking use neo4j embedded ha? can provide me links/tutorials configure spring data neo4j in embedded mode ha proxy.
i wish have 3 neo4j servers , multiple application servers. thanks.

rick,
here example on how pass parameters embedded ha highlyavailablegraphdatabase.
<neo4j:config graphdatabaseservice="graphdatabaseservice" /> <context:property-placeholder location="file:/etc/neo4j-ha.properties" /> <bean id="graphdatabaseservice" class="org.neo4j.kernel.highlyavailablegraphdatabase" destroy-method="shutdown" scope="singleton"> <constructor-arg index="0" value="${database.path}" /> <constructor-arg index="1"> <map> <entry key="ha.server_id" value="${server.id}"></entry> <entry key="ha.server" value="${ha.server.address}:${ha.server.port}"></entry> <entry key="ha.coordinators" value="${coordinators}"></entry> <entry key="enable_remote_shell" value="port=1331"></entry> <entry key="ha.pull_interval" value="1"></entry> </map> </constructor-arg> </bean> also see here: neo4j ha (embedded) via spring?
