Queue Storage Types
The client queue storage type, also defined by your Broker client's client group, may be either volatile or guaranteed.
Queue Type
Description
volatile
The Broker will queue events for your Broker client using local memory. This offers higher performance along with a greater risk of losing events if a hardware, software, or network failure occurs.
guaranteed
The Broker will use a two-phase commit process to queue events for your Broker client. This offers the lowest performance, but very little risk of losing events if a hardware, software, or network failure occurs.
Note:
Storage types may also be defined for a particular event type. See Obtaining Storage Type Property for information on how client group and event type storage specifications interact.
