Vladyslav Diachenko	9b691904ef	BloomShipper: add cache for downloaded blocks (#11394 ) adapted embeddedcache.go to store downloaded bloom blocks on local filesystem. What this PR does / why we need it: This cache will be used by bloom-gateway to not download the blocks each time. In the cache we store the objects(`cachedBlock` struct) that contain: 1. `blockDirectory`: the `path` to the directory where the block was extracted 2. `activeQueriers`: thread-safe counter of active block users. This field is important because we do not want the directory to be removed while it's in use. 3. rest fields are needed for service needs When the downloadingWorker receives this entity, it increases the counter `activeQueriers` and creates blockQuerier wrapper that has `Close` function that will decrease the counter once blockQuerier is not needed anymore. When the cache entry is being removed from the cache, the cache calls the function `removeDirectoryAsync` which asynchronously removes the block's folder. This function checks every `Xms` if there are still active block queriers and once `activeQueriers` count is `0` the folder will be removed. Also, there is a timeout in this function, and once the timeout is reached, the folder will be force removed. Special notes for your reviewer: * If the cache is disabled, then the blocks will be downloaded each time the block is requested. * If the cache is used, the folder will be deleted by embeddedCache when it reaches memory size limit or items count limit. Otherwise, the block's folder will be deleted when `Close` function is called.

Vladyslav Diachenko	45b10effac	embedded cache refactoring (#10989 ) What this PR does / why we need it: refactored embedded cache to allow using it for any types, not only for `string -> []byte`. Also, the new implementation allows passing the callback that will be called for the removed entry. --------- Signed-off-by: Vladyslav Diachenko <vlad.diachenko@grafana.com>	2 years ago

Ashwanth	2902f986a4	cache: Enable embedded cache if no other cache is configured. (#10620 ) What this PR does / why we need it: FIFO cache is replaced by embedded-cache in https://github.com/grafana/loki/pull/6821 This PR enables embedded cache for query range results, chunks cache, index_stats_results and volume_results if no other cache is explicitly configured (redis, memcache).

Christian Haudum	57b384df8f	Auto-expire old items from FIFO cache (#5148 ) * Remove validity from FIFO cache We can remove the validity setting of 1h in 2.4 for the chunks cache because it doesn't reduce memory usage and instead leads to valid chunks being ignore when querying the cache. Chunks are immutable so it doesn't make sense to not return them if they are present in the cache. Closes #4922 Signed-off-by: Christian Haudum <christian.haudum@gmail.com> * Add periodic task to prune old FIFO cache elements As described in #4921 this PR adds a periodic task that prunes expired items from the FIFO cache to free up memory.
