Mengelola sumber daya Azure Cosmos DB untuk Apache Cassandra menggunakan templat Azure Resource Manager
BERLAKU UNTUK: 
Cassandra
Dalam artikel ini, Anda mempelajari cara menggunakan templat Azure Resource Manager untuk membantu menyebarkan dan mengelola akun, ruang kunci, dan tabel Azure Cosmos Anda.
Artikel ini memiliki contoh untuk API hanya untuk akun Cassandra, untuk menemukan contoh untuk akun jenis API lainnya lihat: menggunakan templat Azure Resource Manager dengan API Azure Cosmos DB untuk artikel NoSQL, Gremlin, MongoDB, Tabel .
Penting
- Nama akun dibatasi hingga 44 karakter, semuanya huruf kecil.
- Untuk mengubah nilai throughput, sebarkan ulang template dengan RU yang diperbarui.
- Saat menambahkan atau menghapus lokasi ke akun Azure Cosmos DB, Anda tidak dapat mengubah properti lain secara bersamaan. Operasi ini harus dilakukan secara terpisah.
Untuk membuat salah satu sumber daya Azure Cosmos DB di bawah ini, salin contoh template berikut ke dalam file json baru. Anda dapat secara opsional membuat parameter file json untuk digunakan saat menyebarkan beberapa instans dari sumber daya yang sama dengan nama dan nilai yang berbeda. Ada banyak cara untuk menggunakan templat Azure Resource Manager, termasuk portal Azure,Azure CLI,Azure PowerShell, dan GitHub.
Akun Azure Cosmos DB untuk Cassandra dengan throughput yang disediakan skala otomatis
Templat ini membuat akun Azure Cosmos DB di dua wilayah dengan opsi untuk konsistensi dan failover, dengan ruang kunci dan tabel yang dikonfigurasi untuk throughput skala otomatis. Templat ini juga tersedia untuk penyebaran satu klik dari Azure Quickstart Templates Gallery.
