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

نظرة عامة على المورد
clickhouse_clickpipe على معاملات المستوى الأعلى التالية:
| الوسيطة | مطلوب | الوصف |
|---|---|---|
name | نعم | اسم ClickPipe. |
service_id | نعم | معرّف خدمة ClickHouse Cloud. |
source | نعم | تهيئة المصدر (كتلة مصدر واحدة لكل ClickPipe). |
destination | نعم | تهيئة الوجهة. |
scaling | لا | عدد النسخ المتماثلة وحجمها. القيمة الافتراضية هي نسخة متماثلة واحدة. |
field_mappings | لا | تعيينات حقول مخصّصة بين أعمدة المصدر والوجهة. |
settings | لا | إعدادات ClickPipe المتقدمة. |
stopped | لا | اضبطه على true لإنشاء ClickPipe في حالة توقّف. القيمة الافتراضية هي false. |
id وstate للقراءة فقط، ويجري تعبئتهما بواسطة ClickHouse Cloud بعد الإنشاء.
