title: How to share database connection between different lambda functions
body: <p>I went through <a href="http://blog.rowanudell.com/database-connections-in-lambda/" rel="nofollow noreferrer">some articles</a> about taking advantage of lambda's container and sharing things like database connection between multiple instances, however, what if I have multiple lambda functions accessing the database and I want to have them share the same connection knowing that these functions call each other, for example, an API gateway calls the <code>authenticator</code> lambda function and then calls the <code>insert user</code> function, both of these functions make calls to the database, is it possible for them to share the same connection?</p>
  
  <p>I'm using NodeJS but I can use a different language if it would support that.</p>
