A Go web application which stores a complex json document in a key-value store and supports CRUD operations. HTTP requests are authenticated using O Auth 2.0. The web app also supports complex queries and searching capabilities using Elastic Search and Kibana.

The key-value store used is DynamoDB
The queue used for pub/sub is AWS SQS/ElasticMQ
ElasticSearch is used and visualised using Kibana
The web application stores a complex json document(nested JSON objects) as individual objects in the kv store to support querying based on types.
All Services used in the project uses a local copy, for ex - AWS local dynamodb, AWS local SQS - ElasticMQ
An approach to GraphQL is also visualised.
All HTTP requests are authorised by O Auth 2.0 Implicit Grant Flow.

Sample Commands:

Create Table:

aws dynamodb create-table \
--table-name TableName \
--attribute-definitions AttributeName=PrimaryKey,AttributeType=S \
--key-schema AttributeName=PrimaryKey,KeyType=HASH \
--provisioned-throughput ReadCapacityUnits=1,WriteCapacityUnits=1 \
--endpoint-url http://localhost:8000

Put Item in table:

aws dynamodb put-item --table-name PLAN_TABLE --item file://item.json --endpoint-url http://localhost:8000

Delete item:

aws dynamodb delete-item --table-name PLAN_TABLE --key '{"objectId": {"S": "27283xvx9asdff-104"}}' --endpoint-url http://localhost:8000 --debug

GetItem:

aws dynamodb get-item --table-name PLAN_TABLE --key '{"objectId": {"S": "27283xvx9asdff-104"}}' --endpoint-url http://localhost:8000 --debug

Describe Table:

aws dynamodb describe-table --table-name PLAN_TABLE --endpoint-url http://localhost:8000

Delete table:
