Tools to copy and compare Neo4j Stores

Uses the GraphDatabaseService to read a store and the batch-inserter API to write the target store keeping the node-ids. Copies the index-files as is. Ignores broken nodes and relationships.

Also useful to skip no longer wanted properties or relationships with a certain type. Good for store compaction as it rewrites the store file reclaiming space that is sitting empty.

Change the Neo4j version in pom.xml before running. (Currently 2.2.4)

Store Copy

Usage:

mvn compile exec:java -Dexec.mainClass="org.neo4j.tool.StoreCopy" \
  -Dexec.args="source-dir target-dir [rel,types,to,ignore] [properties,to,ignore] [labels,to,ignore]"

Store Compare

mvn compile exec:java -Dexec.mainClass="org.neo4j.tool.StoreComparer" \
  -Dexec.args="source-dir target-dir [rel,types,to,ignore] [properties,to,ignore]"
