Commutnity edition support dbms.lock.acquisition.timeout?

I use the following Neo4j.

  • Version: 3.5.0
  • Edition: community

Does the Commutnity edition support "dbms.lock.acquisition.timeout"?

According to the manual below, the Community edition does not support transaction management and does not allow for lock timeout settings.

OPERATIONS MANUAL > Transaction management

However, when I actually set the timeout setting (20 seconds) in the Community edition, a transaction waiting for a lock timed out in the 20 seconds.

  • neo4j.conf
# grep dbms.lock.acquisition.timeout ./conf/neo4j.conf 
dbms.lock.acquisition.timeout=20s
  • response message
