يمكن إنشاء جميع أنواع ClickPipes وإدارتها باستخدام المورد clickhouse_clickpipe في موفّر Terraform لـ ClickHouse. تستعرض هذه الصفحة إعداد الموفّر وتقدّم أمثلة على التهيئة لكل نوع ClickPipe مدعوم.

إعداد الموفّر

أصبح دعم ClickPipes متاحًا رسميًا بدءًا من إصدار الموفّر v3.14.0. إذا كنت تستخدم إصدارًا أقدم، فستحتاج إلى إصدار alpha — راجع سجل التغييرات الخاص بالموفّر للاطلاع على التفاصيل.
أضِف موفّر ClickHouse إلى إعدادات Terraform الخاصة بك:
terraform {
  required_providers {
    clickhouse = {
      source  = "ClickHouse/clickhouse"
      version = ">= 3.14.0"
    }
  }
}

provider "clickhouse" {
  organization_id = var.organization_id
  token_key       = var.token_key
  token_secret    = var.token_secret
}

نظرة عامة على المورد

يحتوي المورد clickhouse_clickpipe على معاملات المستوى الأعلى التالية:
الوسيطةمطلوبالوصف
nameنعماسم ClickPipe.
service_idنعممعرّف خدمة ClickHouse Cloud.
sourceنعمتهيئة المصدر (كتلة مصدر واحدة لكل ClickPipe).
destinationنعمتهيئة الوجهة.
scalingلاعدد النسخ المتماثلة وحجمها. القيمة الافتراضية هي نسخة متماثلة واحدة.
field_mappingsلاتعيينات حقول مخصّصة بين أعمدة المصدر والوجهة.
settingsلاإعدادات ClickPipe المتقدمة.
stoppedلااضبطه على true لإنشاء ClickPipe في حالة توقّف. القيمة الافتراضية هي false.
السِّمتان id وstate للقراءة فقط، ويجري تعبئتهما بواسطة ClickHouse Cloud بعد الإنشاء.

الوجهة

يُستخدم القسم destination مع جميع أنواع المصادر:
destination {
  database      = "default"           # Target database. Defaults to "default".
  table         = "my_table"          # Target table name. Required for all sources except CDC.
  managed_table = true                # Let ClickPipes create and manage the table. Defaults to true.

  table_definition {
    engine {
      type      = "MergeTree"         # MergeTree, ReplacingMergeTree, SummingMergeTree, or Null.
    }
    sorting_key   = ["id", "ts"]      # Optional.
    partition_by  = "toYYYYMM(ts)"    # Optional.
  }

  columns {
    name = "id"
    type = "UInt64"
  }

  columns {
    name = "message"
    type = "String"
  }
}
بالنسبة إلى مصادر CDC ‏(Postgres وMySQL وMongoDB وBigQuery)، تُنشأ جداول الوجهة تلقائيًا استنادًا إلى مخطط المصدر — وعادةً ما يلزم فقط database.

التوسيع

تدعم جميع أنواع ClickPipe قسم scaling لضبط عدد النسخ المتماثلة وتخصيص الموارد لها:
scaling {
  replicas               = 2     # Default: 1. Maximum: 10.
  replica_cpu_millicores = 500   # Between 125 and 2000.
  replica_memory_gb      = 2.0   # Between 0.5 and 8.0.
}

استيراد ClickPipes الموجودة

يمكن استيراد ClickPipes الموجودة ضمن حالة Terraform باستخدام كلٍّ من معرّف الخدمة ومعرّف ClickPipe:
terraform import clickhouse_clickpipe.example <service_id>:<clickpipe_id>
