filter?

Type Input<Record<string, any>>

Filter the messages that’ll be processed by the subscriber.

If any single property in the filter doesn’t match an attribute assigned to the message, then the policy rejects the message.

For example, if your SNS topic message contains this in a JSON format.

{
  store: "example_corp",
  event: "order-placed",
  customer_interests: [
     "soccer",
     "rugby",
     "hockey"
  ],
  price_usd: 210.75
}

Then this filter policy accepts the message.

{
  filter: {
    store: ["example_corp"],
    event: [{"anything-but": "order_cancelled"}],
    customer_interests: [
       "rugby",
       "football",

    ],
    price_usd: [{numeric: [">=", 100]}]
