JIT-29004: Enable and disable TTL support

[hiradp]

Here's a sample migration that enables TTLs on table projectsHistoryTable on the column name ttl

'use strict';

var tableName = require('./cs_tables').projectsHistoryTable;

exports.up = function(migrator, config){
  return migrator().enableTTL(tableName, 'ttl');
};

exports.down = function(migrator, config){
  return migrator().disableTTL(tableName, 'ttl');
};

With this implementation, is it possible to enable TTL in the same migration which creates the table?

@tmercswims Unfortunately not. As far as my understanding goes, that's a limitation of the aws-sdk. Modifying a TTL attribute is a different call and requires a table name, which implies that the table needs to exist.

Here's what the create table parameters look like

{
    TableName : "Music",
    KeySchema: [       
        { 
            AttributeName: "Artist", 
            KeyType: "HASH", //Partition key
        },
        { 
            AttributeName: "SongTitle", 
            KeyType: "RANGE" //Sort key
        }
    ],
    AttributeDefinitions: [
        { 
            AttributeName: "Artist", 
            AttributeType: "S" 
        },
        { 
            AttributeName: "SongTitle", 
            AttributeType: "S" 
        }
    ],
    ProvisionedThroughput: {       // Only specified if using provisioned mode
        ReadCapacityUnits: 1, 
        WriteCapacityUnits: 1
    }
}

There isn't a place where I can specify that.

Also @tmercswims, @sean-krail, should we remove Travis and go with GitHub actions since this is a public repo anyways?

[tmercswims]

Gotcha, understood.

And yes, I think we should. I'm already working on a branch to move over.
