Add a new global secondary index that uses the
is_manager attribute as the global secondary index partition key, which is stored under the attribute named
GSI_2_PK. Employee job titles are stored under
Run the following AWS CLI command.
aws dynamodb update-table --table-name employees \ --attribute-definitions AttributeName=GSI_2_PK,AttributeType=S AttributeName=GSI_2_SK,AttributeType=S \ --global-secondary-index-updates file://gsi_manager.json
Wait until the global secondary index has been created. This takes approximately 5 minutes.
Check output of the following command. If “
IndexStatus”: is “
CREATING” you will have to wait until “
IndexStatus” is “
ACTIVE” before continuing to the next step.
aws dynamodb describe-table --table-name employees --query "Table.GlobalSecondaryIndexes.IndexStatus"
The output will initially look like the following.
[ "CREATING", "ACTIVE" ]
You also can script the command to run every 2 seconds using
# Watch checks every 2 seconds by default watch -n 2 "aws dynamodb describe-table --table-name employees --query \"Table.GlobalSecondaryIndexes.IndexStatus\""
Press Ctrl + C to end
watch after the global secondary index has been created.
Wait until the new index is
ACTIVE before proceeding.
[ "ACTIVE", "ACTIVE" ]
Caution: Do not continue until the
ACTIVE on both indexes. Querying the index before it is
ACTIVE will result in a failed query.
