问题 cacheloader : Use case One of main use case where GemFire is used is, where it is used as a fast running cache which holds most recent data (example last 1 month) and all remaining data sits in back-end database. I mean Gemfire data which is 1 month old is overflowed to database after 1 month. However when user is looking for data which was beyond 1 month, we need to go to the database and get the data. Cache loader is suitable for doing this operation on cache misses and gets data from the

问题 I would like to create a Gemfire region in a Spring Boot application. Following this sample, it works well wihout adding database support. If I add database, it will shows error like " Error creating bean with name 'dataSource'".

问题 Is there any way to provide GemFire regionName dynamically during runtime. Currently we are hardCoding the regionName "testRegion". Sample Code is below.

It happens when the config is that ssl-ciphers= and ssl-protocols= or set to any ... So what's the required REST API cipher for Apache Geode? Thanks 回答1: I tested this with a basic cert

问题 I have gemfire client server configured via gfe based xml. The locator, cache server and client cache start through these xml configurations. I populate my Region by getting data from database. The client uses data from this Region. It works very well for about 2 hours but after that the client starts throwing following exception and trace. I don't do any changes to running application. That means the locator and cache server should be running at all times. Any help would be great. Thanks.

问题 Is it possible to have a ClientCache with ClientRegionShortcut.PROXY along with programmatic control over entry TTL settings (i.e. entries present in the server)? I see the entry expiration ttl settings working fine with ClientRegionShortcut.CACHING_PROXY_HEAP_LRU . In this case I can see the entries getting invalidated in server after the configured timeout in seconds, but that is not the case for ClientRegionShortcut.PROXY settings Is it NOT possible to dynamically control the entry-ttl
