Configuration and Settings
Configuration sources
MonkDB reads settings from:
monkdb.yml- CLI flags (
-Ckey=value) - Environment variables (selected runtime knobs)
Typical precedence is runtime flag over static file.
Example file (monkdb.yml)
network.host: _local_,_site_
path:
logs: /data/log
data: /data/data
blobs:
path: /data/blobs
Repository file locations
- Primary source template:
config/monkdb.yml - Distribution config:
app/src/main/dist/config/monkdb.yml - App config copy:
app/config/monkdb.yml - Automation template:
automation_scripts/ansible/templates/monkdb.yml.j2
Common runtime flags
Examples used in this repository:
-Ccluster.name=...-Cnetwork.host=0.0.0.0-Cnetwork.publish_host=...-Ctransport.port=4300-Cnode.name=...-Cdiscovery.seed_hosts=...-Ccluster.initial_master_nodes=...
Node-level settings (examples)
path.data,path.logs,blobs.path- network/transport/http bind and publish addresses
- local JVM and heap sizing via env vars
Cluster-level dynamic settings (examples)
- Governance and lineage feature flags (
governance.enabled,lineage.*,audit.*) - FDW local access gate (
fdw.allow_local) - breaker tuning (
indices.breaker.*)
Logging
Inspect and tune logger levels via cluster settings exposed in sys.cluster['settings']['logger'].
