Cache Client Fault/Recovery

In separated deployment mode, the cache client is loaded to an application process as a binary library. If the application process exits, the cache client also exits. The fault handling methods are described as follows.

**Table 1** Cache client fault scenarios
Scenario	Impact	Handling Method	Remarks
Cache client fault	The write resource quota leaks. The response to distributed requests fails. The communication link is disconnected. The created linear space becomes invalid.	The cache server detects that the client exits based on the link disconnection event, reclaims the write resource quota, seals the linear space, and evicts data to the back-end storage. Information about the invalid link is deleted.	None
Cache client recovery	The communication link needs to be re-established. The cache client performs the initialization and power-on processes again.	The cache server processes the link establishment request.	None
