how many nodes do you have?
If it's around 1M this should be fine
match (n) SET n.value = toFloat(n.value)
, if it's more you probably want to batch it
match (n)
WITH n SKIP 100 LIMIT 100
SET n.value = toFloat(n.value)

Neo4j can do it in 2.7 seconds on my 4 year old laptop.

hi, i installed neo4j on debian and copied my database from a windows
install to the debian server.
I see all nodes and relationships but i do not see any properties when
clicking on a node in the browser.
However i see the property names in the browser Property Keys list

I created a database with many nodes, some nodes store numbers as
properties, but these numbers are stored as string, The numbers contain
many digits like 43.9883999. Can I convert all these strings to
numbers?

You should keep the session open, otherwise you are re-opening a new

See the gremlin docs for running gremlin on top of Neo4j.
You might also want to have a look at the
github.com/neo4j-contrib/neo4j-tinkerpop-api-impl
Which also comes with a procedure to run Gremlin from Cypher, the procedure
implementation should help you in getting started in Java.

It caches on the server.
There are two primary caches; one for query execution plans, and a page cache
for store file contents.
The page cache is important to tune to reduce the read IO required to service
queries, without using too much memory.
The query execution cache is usually fine with its
A 100 friends per customer is a somewhat high cardinality.
Going out four levels you get 100 to the power of 4, 100.000.000 friends out of
10.000, then "distinctified".
There's probably a good chance that the result is just the complete Customer
set.
You should take a look at the query plans for
Neo4j cleans up transaction logs when it check-points, which happens at regular
intervals some times (in minutes) after the database has started.
Have you checked that any transaction logs haven't been deleted since?
Neo4j never reduces the size of the store files; it can at best only re-use the
12 matches
