Solace Solace interface to kdb+


The Solace PubSub+ Event Broker can be used to efficiently stream events and information across cloud, on-premises and within IoT environments. The “+” in PubSub+ indicates its support of wide-ranging functionality beyond publish-subscribe. This includes request-reply, streaming and replay, as well as different qualities of service, such as best-effort and guaranteed delivery.

Use cases

The event broker is used across a number of sectors including

  • airline industry (air-traffic control)
  • financial services (payment processing)
  • retail (supply-chain/warehouse management)

Other sectors
