I'm trying to use Neo4j with Apache Spark Streaming but I am finding
serializability as an issue.
Basically, I want Apache Spark to parse and bundle my data in real time.
After, the data has been bundled it should be stored in the database,
Neo4j. However, I am getting this error:
Hi Mohana,

what you hope to achieve.
Cheers.

something like this
MATCH path=(n)-[*..5]-()
where id(n) = {node_ids}[0]
AND ALL(n in nodes(path) WHERE id(n) IN {node_ids})
AND ALL(r in rels(path) WHERE id(r) IN {rel_ids})
return path

You can't serialize nodes or relationships themselves, they were not meant for
that.
You could use a helper that serializes the node as id + labels + properties
and the relationship as id + type + properties + start-node-id + end-node-id

1. Update your Neo4j version to something more recent.
2. This query was not well handled by the old planner, the new one in 2.2 GA
should do much much better on that.
3. You can use something like this as a workaround meanwhile:
MATCH (me:User {username:'Kaylee83639'})-[:FRIENDS]-(people)

Thanks! I haven't been able to do any real testing against 2.2 yet due to the
couple of issues I've hit. Any way I could get a new build prior to the GA
release?

Hello,
Hi. I'm having problems deleting nodes and relationships from a server-side
plugin.
I have a following code that is supposed to accomplish this:
1. public class Purger {
2.private static final int BATCH_SIZE = 1000;
3.
4. ...
5.
6. public static void
Hi Michael!
This is an example of the code I use:
import org.neo4j.unsafe.batchinsert.BatchInserter;
import org.neo4j.unsafe.batchinsert.BatchInserters;
BatchInserter batchInserter = BatchInserters.inserter(DB_PATH);
batchInserter.createDeferredSchemaIndex(NODE_LABEL).on(id).create();
13 matches
