Set the snapshot frequency for Memgraph Platform?

How can I change the snapshot frequency for Memgraph Platform? I'm running the latest Docker version of the Platform (MG 2.7).

Solution

  • To do this you'll need to modify the Memgraph configuration file. Since you are running a Docker it will involve some copy/edit/copy back operations:

    1. Start Memgraph Platform with including the -v mg_etc:/etc/memgraph flag:

      docker run -it -p 7687:7687 -p 7444:7444 -p 3000:3000 -e MEMGRAPH="--log-level=TRACE"
      -v mg_lib:/var/lib/memgraph
      -v mg_log:/var/log/memgraph
      -v mg_etc:/etc/memgraph
      memgraph/memgraph-platform

    2. Find the CONTAINER ID of the Memgraph Docker:

      docker ps

    3. Copy the configuration file from the container to your local machine:

      docker cp :/etc/memgraph/memgraph.conf memgraph.conf

    4. Open the configuration file with a text editor, and modify the --snapshot-interval-sec option to set the desired snapshot frequency in seconds. Save the changes to the configuration file.

    5. Copy the modified configuration file back to the container:

      docker cp memgraph.conf :/etc/memgraph/memgraph.conf

    Now restart the docker and your new configuration will be loaded.
