Launching a CREATE INDEX ON when the index already exists, in Neo4J

What happens if you replay a CREATE INDEX ON command on a Neo4J database that already has this index. Does Neo4J simply ignore that command?

The first time you will execute it, Neo4j will :

  • Create the index
  • Create a background job to populate it
  • As a query stat, tell you that an index is created

At the second attempt, you will have :

  • No error
  • No impact on the existed index
  • An empty stat for the query (ie. no new index created)

the 2nd invocation of the create index will run, produce no error, but also not report the index alredy exists and in the end you will still only have 1 index
