## Overview
## Create Table
```powershell
aws dynamodb wizard new-table
```
Table is the very basic data container in [[AWS DynamoDB]], so if you want to save some data in DynamoDB, first you need to create a table. You can do that in [[AWS CLI]] like this:
```powershell
aws dynamodb create-table `
--table-name MyTableName `
--attribute-definitions AttributeName=id,AttributeType=S AttributeName=createdAt,AttributeType=S `
--key-schema AttributeName=id,KeyType=HASH AttributeName=createdAt,KeyType=RANGE `
--provisioned-throughput ReadCapacityUnits=1,WriteCapacityUnits=1
```
This call will create a DynamoDB table called `MyTable` with [composite primary key](https://dynobase.dev/dynamodb-keys/) where attribute `id` is the Hash Key, and `createdAt` is the Range Key. It means that items with the same `id` will be assigned to the same partition, and they will be sorted on the date of their creation.
Moreover, we're specifying `--provisioned-throughput` argument which will create a table in [provisioned capacity mode](https://dynobase.dev/dynamodb-capacity-modes/#provisioned-capacity) with just one [Write Capacity Unit (WCU)](https://dynobase.dev/dynamodb-capacity-modes/#write-capacity) and one [Read Capacity Unit (RCU)](https://dynobase.dev/dynamodb-capacity-modes/#read-capacity).
If you don't like the "shorthand syntax" where input parameters are specified in comma-separated fashion, you can also use JSON format like this:
```powershell
aws dynamodb create-table `
--table-name MyTableName `
--attribute-definitions '[{"AttributeName":"id", "AttributeType":"S"}, {"AttributeName":"createdAt", "AttributeType":"S"}]' `
--key-schema '[{"AttributeName":"id", "KeyType":"HASH"}, {"AttributeName":"createdAt", "KeyType":"RANGE"}]' `
--provisioned-throughput '{"ReadCapacityUnits": 1, "WriteCapacityUnits": 1}'
```
