I have the same errors in OrientDB logs but the query aborts BEFORE it
finishes at 1260 ( the number of records from 'Firma' class being 5
million) :
2018-02-04 00:39:11:369 WARNI {db=ter1050} This database instance has 1260
open command/query result sets, please make sure you c
I am running some Gremlin query in OrientDB studio for this to happen:
g.V().hasLabel("Firma").sideEffect{
g.V().hasLabel("Adresa").has("adresa",it.get().property('adresa').value()).addE('Location').from(it.get()).next()
}
It might be something wrong with my query because I am a Gremlin
newbie.....or with OrientDB-Gremlin implementation
