    # Neo4j configuration
    #
    # For more details and a complete list of settings, please see
    # https://neo4j.com/docs/operations-manual/current/reference/configuration-settings/
    #*****************************************************************

    # The name of the database to mount
    dbms.active_database=hiveage.db

    # Paths of directories in the installation.
    dbms.directories.data=/data/neo4j_data/hive_lineage/hiveage.db

    dbms.directories.plugins=plugins

    # This setting constrains all `LOAD CSV` import files to be under the `import` directory. Remove or comment it out to
    # allow files to be loaded from anywhere in the filesystem; this introduces possible security problems. See the
    # `LOAD CSV` section of the manual for details.
    dbms.directories.import=import

    # Whether requests to Neo4j are authenticated.
    # To disable authentication, uncomment this line
    dbms.security.auth_enabled=true

    # Enable this to be able to upgrade a store from an older version.
    dbms.allow_upgrade=true

    # Java Heap Size: by default the Java heap size is dynamically
    # calculated based on available system resources.
    # Uncomment these lines to set specific initial and maximum
    # heap size.

    # The amount of memory to use for mapping the store files, in bytes (or
    # kilobytes with the 'k' suffix, megabytes with 'm' and gigabytes with 'g').
    # If Neo4j is running on a dedicated server, then it is generally recommended
    # to leave about 2-4 gigabytes for the operating system, give the JVM enough
    # heap to hold all your transaction state and query context, and then leave the
    # rest for the page cache.
    # The default page cache memory assumes the machine is dedicated to running
    # Neo4j, and is heuristically set to 50% of RAM minus the max Java heap size.
    dbms.memory.pagecache.size=20G

    #*****************************************************************
    # Network connector configuration
    #*****************************************************************

    # With default configuration Neo4j only accepts local connections.
    # To accept non-local connections, uncomment this line:
    dbms.connectors.default_listen_address=0.0.0.0

    # You can also choose a specific network interface, and configure a non-default
    # port for each connector, by setting their individual listen_address.

    # The address at which this server can be reached by its clients. This may be the server's IP address or DNS name, or
    # it may be the address of a reverse proxy which sits in front of the server. This setting may be overridden for
    # individual connectors below.
    dbms.connectors.default_advertised_address=0.0.0.0

    # You can also choose a specific advertised hostname or IP address, and
    # configure an advertised port for each connector, by setting their
    # individual advertised_address.

    # Bolt connector
    dbms.connector.bolt.enabled=true

    #*****************************************************************
    # SSL system configuration
    #*****************************************************************

    # Names of the SSL policies to be used for the respective components.

    # The legacy policy is a special policy which is not defined in
    # the policy configuration section, but rather derives from
    # dbms.directories.certificates and associated files
    # (by default: neo4j.key and neo4j.cert). Its use will be deprecated.

    # The policies to be used for connectors.
    #
    # N.B: Note that a connector must be configured to support/require
    # SSL/TLS for the policy to actually be utilized.

    #https.ssl_policy=legacy

    #*****************************************************************
    # SSL policy configuration
    #*****************************************************************

    # Each policy is configured under a separate namespace, e.g.
    # dbms.ssl.policy.<policyname>.*
    #
    # The example settings below are for a new policy named 'default'.

    # The base directory for cryptographic objects. Each policy will by
    # default look for its associated objects (keys, certificates, ...)
    # under the base directory.
    #
    # Every such setting can be overriden using a full path to
    # the respective object, but every policy will by default look
    # for cryptographic objects in its base location.
    #
    # Mandatory setting

    #dbms.ssl.policy.default.base_directory=certificates/default

    # Allows the generation of a fresh private key and a self-signed
    # certificate if none are found in the expected locations. It is
    # recommended to turn this off again after keys have been generated.
    #
    # Keys should in general be generated and distributed offline
    # by a trusted certificate authority (CA) and not by utilizing
    # this mode.

    #dbms.ssl.policy.default.allow_key_generation=false

    # Enabling this makes it so that this policy ignores the contents
    # of the trusted_dir and simply resorts to trusting everything.
    #
    # Use of this mode is discouraged. It would offer encryption but no security.

    #dbms.ssl.policy.default.trust_all=false

    # The private key for the default SSL policy. By default a file
    # named private.key is expected under the base directory of the policy.
    # It is mandatory that a key can be found or generated.

    #dbms.ssl.policy.default.private_key=

    # The private key for the default SSL policy. By default a file
    # named public.crt is expected under the base directory of the policy.
    # It is mandatory that a certificate can be found or generated.

    #dbms.ssl.policy.default.public_certificate=

    # The certificates of trusted parties. By default a directory named
    # 'trusted' is expected under the base directory of the policy. It is
    # mandatory to create the directory so that it exists, because it cannot
    # be auto-created (for security purposes).
    #
    # To enforce client authentication client_auth must be set to 'require'!

    #dbms.ssl.policy.default.trusted_dir=

    # Client authentication setting. Values: none, optional, require
    # The default is to require client authentication.
    #
    # Servers are always authenticated unless explicitly overridden
    # using the trust_all setting. In a mutual authentication setup this
    # should be kept at the default of require and trusted certificates
    # must be installed in the trusted_dir.

    #dbms.ssl.policy.default.client_auth=require

    # A comma-separated list of allowed TLS versions.
    # By default TLSv1, TLSv1.1 and TLSv1.2 are allowed.

    #dbms.ssl.policy.default.tls_versions=

    # A comma-separated list of allowed ciphers.
