類型

是否必須

描述

endpoint

string

igraph實例對應的endpoint

username

string

igraph請求的username

password

string

igraph請求的password

graph_name

string

要寫入的igraph圖名

label_name

string

要寫入的igraph邊或者節點名

pk_field

string

igraph sink表的pk字段

sk_field

string

igraph sink表的sk字段

cmd_field

string

igraph sink表的cmd字段,取值為add、delete,用于表示這條記錄是新增或刪除請求

request_retry

int

否,默認0

請求igraph的重試次數,默認為0

dry_run

boolean

否,默認false

如果dry_run為true,只做測試,不會真實寫入igraph

async

boolean

否,默認為 false

打開會使用異步模式,寫入性能會有提升

需要注意內容:

  • pk_field為寫入igraph表的主鍵,必填字段

  • cmd_field取值為add、delete,表示是插入或刪除請求。如果是add請求,默認需要傳入表的全部字段,如果是update請求默認需要全部字段,如果需要支持部分字段的更新連續管理員配置

  • 如果對邊進行delete操作,只填寫pkey 則默認刪除這個起點出發的全部邊,如果填寫pkey和skey則只刪除一條邊數據

  • graph_name 為寫入igraph的圖名

  • label_name 為寫入igraph圖的節點或者邊的label

  • request_retry,為了避免網絡抖動等原因,設置寫入igraph的重試請求次數

  • dry_run,為true時用作測試,會打log,不寫igraph。
