                How to deal with JWT expiration?
              
          
    First of all, please note that token expiration and revoking are two different things.

Expiration only happens for web apps, not for native mobile apps, because native apps never expire.
Revoking only happens when (1) uses click the logout button on the website or native Apps;(2) users reset their passwords; (3) users revoke their tokens explicitly in the administration panel.

1. How to hadle JWT expiration

A JWT token that never expires is dangerous if the token is stolen then someone can always access the user's data.
Quoted from JWT RFC:

  
## dynamodb.java
private Result getPeopleByGSI(@NotNull final String indexedReference, final String... attributes) {
        // make reference the index
        final DynamoDbIndex<People> index = DynamoUtil.peopleTable.index("someIndexedAttribute-index");
        // Apply value to the indexed attribute (as the PartitionKey)
        final QueryConditional queryConditional = QueryConditional.keyEqualTo(
                Key.builder().partitionValue(indexedReference).build());

        // Compose Filter expressions
        final List<String> expressions = new ArrayList<>();
        final Expression.Builder expressionBuilder = Expression.builder();
