André Cruz	9a0792139c	Decrease test flakiness ... Fix flaky TestACLResolver_Client/Concurrent-Token-Resolve and TestCacheNotifyPolling	4 years ago
Matt Keeler	be01c4241d	Default Cache rate limiting options in New ... Also get rid of the TestCache helper which was where these defaults were happening previously.	4 years ago
Pierre Souchay	505de6dc29	Added ratelimit to handle throtling cache (#8226) ... This implements a solution for #7863 It does: Add a new config cache.entry_fetch_rate to limit the number of calls/s for a given cache entry, default value = rate.Inf Add cache.entry_fetch_max_burst size of rate limit (default value = 2) The new configuration now supports the following syntax for instance to allow 1 query every 3s: command line HCL: -hcl 'cache = { entry_fetch_rate = 0.333}' in JSON { "cache": { "entry_fetch_rate": 0.333 } }	4 years ago
Matt Keeler	8837907de4	Make the Agent Cache more Context aware (#8092) ... Blocking queries issues will still be uncancellable (that cannot be helped until we get rid of net/rpc). However this makes it so that if calling getWithIndex (like during a cache Notify go routine) we can cancell the outer routine. Previously it would keep issuing more blocking queries until the result state actually changed.	5 years ago
Daniel Nephin	5fe7043439	agent/cache: Make all cache options RegisterOptions ... Previously the SupportsBlocking option was specified by a method on the type, and all the other options were specified from RegisterOptions. This change moves RegisterOptions to a method on the type, and moves SupportsBlocking into the options struct. Currently there are only 2 cache-types. So all cache-types can implement this method by embedding a struct with those predefined values. In the future if a cache type needs to be registered more than once with different options it can remove the embedded type and implement the method in a way that allows for paramaterization.	5 years ago
Paul Banks	96b9b95a19	Add cache.Notify to abstract watching for cache updates for types that support blocking semantics. (#4695)	6 years ago
Paul Banks	88388d760d	Support Agent Caching for Service Discovery Results (#4541) ... * Add cache types for catalog/services and health/services and basic test that caching works * Support non-blocking cache types with Cache-Control semantics. * Update API docs to include caching info for every endpoint. * Comment updates per PR feedback. * Add note on caching to the 10,000 foot view on the architecture page to make the new data path more clear. * Document prepared query staleness quirk and force all background requests to AllowStale so we can spread service discovery load across servers.	6 years ago
Paul Banks	43b48bc06b	Get agent cache tests passing without global hit count (which is racy). ... Few other fixes in here just to get a clean run locally - they are all also fixed in other PRs but shouldn't conflict. This should be robust to timing between goroutines now.	7 years ago
Mitchell Hashimoto	45e49f31de	agent/cache: change behavior to return error rather than retry ... The cache behavior should not be to mask errors and retry. Instead, it should aim to return errors as quickly as possible. We do that here.	7 years ago
Mitchell Hashimoto	e3c1162881	agent/cache: Reorganize some files, RequestInfo struct, prepare for partitioning	7 years ago
Mitchell Hashimoto	975be337a9	agent/cache: blank cache key means to always fetch	7 years ago
Mitchell Hashimoto	1cfb0f1922	agent/cache: initial kind-of working cache	7 years ago
