Configure custom flags

Apply custom flags

For each component has a configuration entry, it defines in CRD as config which is a map structure, it will be loaded by configmap.

// Config defines a graphd configuration load into ConfigMap
Config map[string]string `json:"config,omitempty"`

The following example will show you how to make configuration changes in CRD, i.e. for any given options --foo=bar in conf files, .config.foo could be applied like:

apiVersion: apps.nebula-graph.io/v1alpha1
kind: NebulaCluster
metadata:
  name: nebula
  namespace: default
spec:
  graphd:
    resources:
      requests:
        cpu: "500m"
        memory: "500Mi"
      limits:
        cpu: "1"
        memory: "1Gi"
    replicas: 1
    image: vesoft/nebula-graphd
    version: v3.6.0
    storageClaim:
      resources:
        requests:
          storage: 2Gi
      storageClassName: ebs-sc
    config:
      "enable_authorize": "true"
      "auth_type": "password"
      "foo": "bar"
...

Afterward, the custom flags enable_authorize, auth_type and foo will be configured and overwritten by configmap.

Dynamic runtime flags

This a dynamic runtime flags table, the pod rolling update will not be triggered after you apply updates in the scenario:

  • All flags updated are in this table
Flag Description Default
minloglevel Log level, 0, 1, 2, 3 for INFO, WARNING, ERROR, FATAL respectively 0
v Verbose log level, 1, 2, 3, 4, the higher of the level, the more verbose of the logging 0
accept_partial_success This flag is only used for Read-only access, and Modify access always treats partial success as an error false
session_reclaim_interval_secs Period we try to reclaim expired sessions 60
max_allowed_query_size Maximum sentence length, unit byte 4194304
system_memory_high_watermark_ratio System memory high watermark ratio, cancel the memory checking when the ratio greater than 1.0 0.8
ng_black_box_file_lifetime_seconds Black box log files expire time 1800
memory_tracker_limit_ratio Trackable memory ratio (trackable_memory / (total_memory - untracked_reserved_memory) ) 0.8
memory_tracker_untracked_reserved_memory_mb Untracked reserved memory in Mib 50
memory_tracker_detail_log Enable log memory tracker stats periodically false
memory_tracker_detail_log_interval_ms Log memory tacker stats interval in milliseconds 60000
memory_purge_enabled Enable memory background purge (if jemalloc is used) true
memory_purge_interval_seconds Memory background purge interval in seconds 10
heartbeat_interval_secs Heartbeat interval in seconds 10

raft_rpc_timeout_ms RPC timeout for raft client (ms) 500
query_concurrently Whether turn on query in multiple thread true
wal_ttl Recycle Raft WAL 14400
auto_remove_invalid_space Whether remove outdated space data true
snapshot_part_rate_limit The rate limit in bytes when leader synchronizes snapshot data 10485760

rebuild_index_part_rate_limit The rate limit in bytes when leader synchronizes rebuilding index 4194304
prioritize_intra_zone_reading Prioritize to send read queries to storaged in the same zone false
stick_to_intra_zone_on_failure Stick to intra zone routing if unable to find the storaged hosting the requested part in the same zone. false
