Amazonite AWS SDK

example workflow

Amazonite is an unofficial AWS SDK for Crystal.

Usage

Here's an example that creates a table in DynamoDB:

require "amazonite/dynamodb_v2"

private alias DB = Amazonite::DynamoDBV2

model = DB::CreateTableInput.new(
  [
    DB::AttributeDefinition.new("Artist", DB::ScalarAttributeType::S),
    DB::AttributeDefinition.new("SongTitle", DB::ScalarAttributeType::S)
  ],
  "Music",
  [
    DB::KeySchemaElement.new("Artist", DB::KeyType::Hash),
    DB::KeySchemaElement.new("SongTitle", DB::KeyType::Range)
  ],
  provisioned_throughput: DB::ProvisionedThroughput.new(10, 5),
)

client = DB::Client.new # read credentials from environment variables
response = client.create_table(model)

puts response.http.status_code # 200
result = response.result
puts result.table_description.try &.table_name # Music
puts result.table_description.try &.attribute_definitions.try &.[0].attribute_name # Artist

Output:

200
Music
Artist
