When does exactly garbage collector kicks in at Memgraph?

I'm running a Memgraph Platform and I have about 600 000 nodes and relations it my graph. I cleared the database using MATCH (n) DETACH DELETE(n) but the release of the memory is not instant. I can see that after some time (few dozen of seconds) the memory is freed. Can I some how make this faster?

How often is garbage collector run in Memgraph?

Solution

  • In the worst case scenario garbage collector should free it after a 30 seconds. This time interval can be configured using the flag --storage-gc-cycle-sec. 30 is the default value.
