# Membuat tampilan Katalog Data menggunakan AWS Glue APIs
Anda dapat menggunakan AWS Glue [CreateTable](https://docs.aws.amazon.com/glue/latest/webapi/API_CreateTable.html), dan [UpdateTable](https://docs.aws.amazon.com/glue/latest/webapi/API_UpdateTable.html) APIs untuk membuat dan memperbarui tampilan di Katalog Data. `UpdateTable`Operasi `CreateTable` dan memiliki `TableInput` struktur baru untuk`ViewDefinition`, sementara,`SearchTables`,`GetTable`, `GetTables``GetTableVersion`, `GetTableVersions` operasi menyediakan sintaks keluaran mereka untuk tampilan. `ViewDefinition` Selain itu, ada `Status` bidang baru dalam output `GetTable` API.
Dua AWS Glue koneksi baru tersedia untuk memvalidasi dialek SQL untuk setiap mesin kueri yang didukung, dan Amazon Amazon Athena Redshift.
The `CreateTable` dan `UpdateTable` APIs asinkron bila digunakan dengan tampilan. Ketika ini APIs dipanggil dengan beberapa dialek SQL, panggilan divalidasi dengan masing-masing mesin untuk menentukan apakah dialek dapat dijalankan pada mesin itu, dan apakah skema tampilan yang dihasilkan dari masing-masing dialek cocok. AWS Glue Layanan ini menggunakan koneksi ini untuk melakukan panggilan internal ke mesin analitik. Panggilan ini mensimulasikan apa yang mesin lakukan untuk memvalidasi jika `CREATE VIEW` atau `ALTER VIEW` SQL DDL dijalankan pada mesin.
Jika SQL yang disediakan valid, dan skema cocok antara dialek tampilan, AWS Glue API secara atomik melakukan hasilnya. Atomicity memungkinkan tampilan dengan beberapa dialek dibuat atau diubah tanpa downtime.

# Membuat AWS Glue koneksi untuk memvalidasi status
Untuk membuat atau memperbarui AWS Glue Data Catalog tampilan menggunakan `CreateTable` atau `UpdateTable` operasi, Anda harus membuat jenis AWS Glue koneksi baru untuk validasi, dan menyediakannya ke mesin analitik yang didukung. Koneksi ini diperlukan untuk menggunakan tampilan Katalog Data dengan Athena atau Amazon Redshift. Anda dapat membuat koneksi ini hanya menggunakan AWS CLI, AWS SDKs, atau AWS Glue APIs. Anda tidak dapat menggunakan Konsol Manajemen AWS untuk membuat AWS Glue koneksi.
**catatan**
Jika peran penentu tampilan dan pemanggilan peran `CreateTable` atau `UpdateTable` berbeda, maka keduanya memerlukan `glue:PassConnection` izin dalam pernyataan kebijakan IAM mereka.
Untuk informasi selengkapnya, lihat dokumentasi [create-connection](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/glue/create-connection.html) AWS CLI .
**AWS CLI perintah untuk membuat koneksi**
Berikut ini adalah AWS CLI perintah untuk membuat koneksi:
```
aws glue create-connection --region us-east-1
--endpoint-url https://glue.us-east-1.amazonaws.com
--cli-input-json file:///root/path/to/create-connection.json
```
**AWS CLI masukan JSON**
Untuk Amazon Redshift:
```
{
"CatalogId": "123456789012",
"ConnectionInput": {
"ConnectionType": "VIEW_VALIDATION_REDSHIFT",
"Name": "views-preview-cluster-connection-2",
"Description": "My first Amazon Redshift validation connection",
"ConnectionProperties": {
"DATABASE": "dev",
"CLUSTER_IDENTIFIER": "glue-data-catalog-views-preview-cluster"
}
}
}
```
Untuk Amazon Athena:
```
{
"CatalogId": "123456789012",
"ConnectionInput": {
"ConnectionType": "VIEW_VALIDATION_ATHENA",
"Name": "views-preview-cluster-connection-3",
"Description": "My first Amazon Athena validation connection",
"ConnectionProperties": {
"WORKGROUP_NAME": "workgroup-name"
}
}
}
```
# Memvalidasi status pembuatan tampilan
Saat Anda menjalankan `UpdateTable` operasi `CreateTable` atau, `Status` bidang untuk output `GetTable` API menunjukkan detail status pembuatan tampilan. Untuk `create` permintaan di mana tabel belum ada, AWS Glue buat tabel kosong selama proses asinkron. Saat menelepon`GetTable`, Anda dapat meneruskan flag boolean opsional`IncludeStatusDetails`, yang menampilkan informasi diagnostik tentang permintaan tersebut. Dalam kasus kegagalan, bendera ini menunjukkan pesan kesalahan dengan status individual dari setiap dialek.
Kesalahan selama operasi pembuatan, baca, perbarui, dan hapus (CRUD) tampilan dapat terjadi baik selama pemrosesan di layanan AWS Glue/Lake Formation atau selama validasi tampilan SQL di Amazon Redshift atau Athena. Ketika kesalahan terjadi selama validasi di mesin, AWS Glue layanan memberikan pesan kesalahan bahwa mesin kembali.
**Bidang status**
Berikut ini adalah bidang status:
+ Status: status generik, yang agnostik untuk berbagai jenis pekerjaan:
+ DIANTREKAN
+ IN\$1PROGRESS
+ BERHASIL
+ FAILED
+ Tindakan - Menunjukkan tindakan mana yang dipanggil di atas meja, saat ini hanya `CREATE` atau `UPDATE` operasi yang tersedia.
Membedakan antara `UPDATE` dan `CREATE` operasi penting saat bekerja dengan pandangan. Jenis operasi menentukan bagaimana Anda harus melanjutkan dengan query tabel.
`UPDATE`Operasi menandakan bahwa tabel sudah ada di Katalog Data. Dalam hal ini, Anda dapat melanjutkan kueri tabel yang dibuat sebelumnya tanpa masalah. Di sisi lain, `CREATE ` operasi menunjukkan bahwa tabel belum pernah berhasil dibuat sebelumnya. Jika tabel ditandai untuk`CREATE`, mencoba untuk query itu akan gagal karena tabel belum ada dalam sistem. Oleh karena itu, penting untuk mengidentifikasi jenis operasi (UPDATE atau CREATE) sebelum mencoba untuk query tabel.
+ RequestedBy — ARN pengguna yang meminta perubahan asinkron.
+ UpdatedBy ARN pengguna yang terakhir mengubah proses perubahan asinkron secara manual, seperti meminta pembatalan atau modifikasi.
+ Kesalahan - Bidang ini hanya muncul ketika status **GAGAL**. Ini adalah pesan pengecualian tingkat induk. Mungkin ada kesalahan yang berbeda untuk setiap dialek.
+ ErrorCode Jenis pengecualian.
+ ErrorMessage — deskripsi singkat tentang pengecualian.
+ RequestTime — string tanggal berformat ISO 8601 yang menunjukkan waktu perubahan dimulai.
+ UpdateTime — string tanggal berformat ISO 8601 yang menunjukkan waktu status terakhir diperbarui.
# Status dan operasi asinkron
Saat Anda menjalankan `glue:CreateTable` permintaan, pembuatan asinkron tampilan Katalog Data dimulai. Di bagian berikut, dokumen ini menjelaskan AWS Glue tampilan yang tersedia dalam `glue:GetTable` respons. `Status` Untuk singkatnya, bagian ini menghilangkan respons penuh.
```
{
"Table": {
...
"Status": {
...
"Action": "CREATE",
"State": "QUEUED",
}
}
}
```
Kedua atribut di atas mewakili informasi diagnostik penting yang menunjukkan keadaan operasi asinkron, serta tindakan yang dapat dilakukan pada tampilan ini. Di bawah ini adalah nilai yang mungkin yang dapat diambil oleh atribut ini.
1. `Status.Action`
1. CREATE
1. UPDATE
1. `Status.State`
1. DIANTREKAN
1. IN\$1PROGRESS
1. BERHASIL
1. FAILED
Penting juga untuk dicatat bahwa beberapa pembaruan pada tampilan Katalog Data tidak memerlukan operasi asinkron. Misalnya, seseorang mungkin ingin memperbarui `Description` atribut tabel. Karena ini tidak memerlukan operasi asinkron, metadata tabel yang dihasilkan tidak akan memilikinya`Status`, dan atributnya akan menjadi. `NULL`
```
{
"Table": {
...,
"Description": "I changed this attribute!"
}
}
```
Selanjutnya, topik ini mengeksplorasi bagaimana informasi status di atas dapat memengaruhi operasi yang dapat dilakukan pada suatu AWS Glue tampilan.
**lem: CreateTable**
Tidak ada perubahan untuk API ini jika dibandingkan dengan bagaimana `glue:CreateTable` fungsi untuk tabel Glue apa pun. `CreateTable`dapat dipanggil untuk nama tabel apa pun yang belum ada.
**lem: UpdateTable**
Operasi ini tidak dapat dilakukan pada AWS Glue tampilan yang memiliki informasi status berikut:
1. Tindakan == CREATE dan State == ANTRIAN
1. Tindakan == BUAT dan Status == IN\$1PROGRESS
1. Tindakan == BUAT dan status == GAGAL
1. Tindakan == PEMBARUAN dan status == ANTRIAN
1. Tindakan == PEMBARUAN dan status == IN\$1PROGRESS
Untuk meringkas, Anda dapat memperbarui tampilan Katalog Data hanya jika memenuhi persyaratan berikut.
1. Ini telah berhasil dibuat untuk pertama kalinya.
1. Tindakan == CREATE dan State == SUKSES
1. Ini telah mencapai status terminal setelah operasi pembaruan asinkron.
1. Tindakan == PEMBARUAN dan Status == SUKSES
1. Tindakan == PEMBARUAN dan Status == GAGAL
1. Ini memiliki atribut `NULL` status sebagai hasil dari pembaruan sinkron.
**lem: DeleteTable**
Tidak ada perubahan untuk operasi ini jika dibandingkan dengan bagaimana `glue:DeleteTable` fungsi untuk AWS Glue tabel apa pun. Anda dapat menghapus tampilan Katalog Data terlepas dari statusnya.
**lem: GetTable**
Tidak ada perubahan untuk operasi ini jika dibandingkan dengan bagaimana `glue:GetTable` fungsi untuk AWS Glue tabel apa pun. Namun, Anda tidak dapat menanyakan tampilan Katalog Data dari mesin analitik hingga berhasil dibuat untuk pertama kalinya. `Action == CREATE and State == SUCCESS`. Setelah berhasil membuat tampilan Katalog Data untuk pertama kalinya, Anda dapat melakukan kueri tampilan terlepas dari statusnya.
**catatan**
Semua informasi di bagian ini berlaku untuk semua bacaan tabel APIs seperti`GetTable`,`GetTables`, dan`SearchTables`.
# Lihat skenario kegagalan pembuatan selama operasi asinkron
Contoh berikut mewakili jenis kesalahan yang mungkin timbul dari `CreateTable` atau `UpdateTable` melihat panggilan API. Mereka tidak lengkap karena permukaan kesalahan kegagalan kueri SQL cukup besar.
## Skenario 1: Kegagalan kueri Amazon Redshift
Kueri yang disediakan untuk Amazon Redshift menyertakan nama tabel yang salah eja tidak dapat ditemukan di Katalog Data selama validasi. Kesalahan yang dihasilkan ditampilkan di `Status` bidang dalam `GetTable` respons untuk tampilan.
