dio-desafio-dynamodb's Introduction

Serviço utilizado

  • Amazon DynamoDB
  • Amazon CLI para execução em linha de comando

Comandos para execução do experimento:

  • Criar uma tabela
aws dynamodb create-table \
    --table-name Music \
    --attribute-definitions \
        AttributeName=Artist,AttributeType=S \
        AttributeName=SongTitle,AttributeType=S \
    --key-schema \
        AttributeName=Artist,KeyType=HASH \
        AttributeName=SongTitle,KeyType=RANGE \
    --provisioned-throughput \
        ReadCapacityUnits=10,WriteCapacityUnits=5
  • Inserir um item
aws dynamodb put-item \
    --table-name Music \
    --item file://itemmusic.json \
  • Inserir múltiplos itens
aws dynamodb batch-write-item \
    --request-items file://batchmusic.json
  • Criar um index global secundário baeado no título do álbum
aws dynamodb update-table \
    --table-name Music \
    --attribute-definitions AttributeName=AlbumTitle,AttributeType=S \
    --global-secondary-index-updates \
        "[{\"Create\":{\"IndexName\": \"AlbumTitle-index\",\"KeySchema\":[{\"AttributeName\":\"AlbumTitle\",\"KeyType\":\"HASH\"}], \
        \"ProvisionedThroughput\": {\"ReadCapacityUnits\": 10, \"WriteCapacityUnits\": 5      },\"Projection\":{\"ProjectionType\":\"ALL\"}}}]"
  • Criar um index global secundário baseado no nome do artista e no título do álbum
aws dynamodb update-table \
    --table-name Music \
    --attribute-definitions\
        AttributeName=Artist,AttributeType=S \
        AttributeName=AlbumTitle,AttributeType=S \
    --global-secondary-index-updates \
        "[{\"Create\":{\"IndexName\": \"ArtistAlbumTitle-index\",\"KeySchema\":[{\"AttributeName\":\"Artist\",\"KeyType\":\"HASH\"}, {\"AttributeName\":\"AlbumTitle\",\"KeyType\":\"RANGE\"}], \
        \"ProvisionedThroughput\": {\"ReadCapacityUnits\": 10, \"WriteCapacityUnits\": 5      },\"Projection\":{\"ProjectionType\":\"ALL\"}}}]"
  • Criar um index global secundário baseado no título da música e no ano
aws dynamodb update-table \
    --table-name Music \
    --attribute-definitions\
        AttributeName=SongTitle,AttributeType=S \
        AttributeName=SongYear,AttributeType=S \
    --global-secondary-index-updates \
        "[{\"Create\":{\"IndexName\": \"SongTitleYear-index\",\"KeySchema\":[{\"AttributeName\":\"SongTitle\",\"KeyType\":\"HASH\"}, {\"AttributeName\":\"SongYear\",\"KeyType\":\"RANGE\"}], \
        \"ProvisionedThroughput\": {\"ReadCapacityUnits\": 10, \"WriteCapacityUnits\": 5      },\"Projection\":{\"ProjectionType\":\"ALL\"}}}]"
  • Pesquisar item por artista
aws dynamodb query \
    --table-name Music \
    --key-condition-expression "Artist = :artist" \
    --expression-attribute-values  '{":artist":{"S":"Iron Maiden"}}'
  • Pesquisar item por artista e título da música
aws dynamodb query \
    --table-name Music \
    --key-condition-expression "Artist = :artist and SongTitle = :title" \
    --expression-attribute-values file://keyconditions.json
  • Pesquisa pelo index secundário baseado no título do álbum
aws dynamodb query \
    --table-name Music \
    --index-name AlbumTitle-index \
    --key-condition-expression "AlbumTitle = :name" \
    --expression-attribute-values  '{":name":{"S":"Fear of the Dark"}}'
  • Pesquisa pelo index secundário baseado no nome do artista e no título do álbum
aws dynamodb query \
    --table-name Music \
    --index-name ArtistAlbumTitle-index \
    --key-condition-expression "Artist = :v_artist and AlbumTitle = :v_title" \
    --expression-attribute-values  '{":v_artist":{"S":"Iron Maiden"},":v_title":{"S":"Fear of the Dark"} }'
  • Pesquisa pelo index secundário baseado no título da música e no ano
aws dynamodb query \
    --table-name Music \
    --index-name SongTitleYear-index \
    --key-condition-expression "SongTitle = :v_song and SongYear = :v_year" \
    --expression-attribute-values  '{":v_song":{"S":"Wasting Love"},":v_year":{"S":"1992"} }'
