JordanRushing 1dc0d978e4 Add a Ring to IndexGateway (#5358) ... * Begin to add a Ring to IndexGateway Signed-off-by: Jordan Rushing <jordan.rushing@grafana.com> * Implement missing methods for IndexGateway. - Implement missing methods for the IndexGateway to be used as a BasicLifecyclerDelegate. The methods are stored in a lifecycle file and follow the same approach of the Ruler ring - Make Gateway public and add missing parameters to the IndexGateway's initialization method * Fix failing linter Signed-off-by: Jordan Rushing <jordan.rushing@grafana.com> * Implement IndexGateway support for dynamic configs. - Add memberlist as a dependency of the IndexGateway - Add IndexGateway support for the common configuration section - Modify Loki to register IndexGateway flags. This fixes the default flag values for the IndexGateway - Make IndexGateway configurations public. Without this, we can't use them. * Implement NewBasicService for the IndexGateway. - If IndexGateway is running with a ring, it uses the IdleService. Otherwise, it uses the BasicService - Implement IndexGateway support to handle ring HTTP pages * Test IndexGateway dynamic configuration. * Implement new IndexGatewayGRPCPool entity. * Make IndexGateway attributes public. * Implement IndexGatewayRing reader. - Implement new IndexGatewayRing service - Add IndexGatewayRing as a Store dependency - Modify store to pass IndexGatewayRing as a parameter - Implement IndexGatewayClient ring mode * Implement Ring mode in the IndexGatewayClient. - Moves IndexGateway configuration to the IndexGatewayClient struct within the boltdb-shipper - Reuse the IndexGatewayClient everywhere - Implement IndexGateway gRPC pool * Add new ring index gateway parameter to new Store calls. * Use errors.Wrap instead of fmt.Errorf. * Extract tenantID from context instead of iterating on queries. * Remove indexGateway ring param. - Instead, add it to the store configuration and bubble it down to deeper modules. * Split IndexGateway server from client implementation. * Fix imports order. * Remove ring as parameter from IndexGateway-related funcs. * Fix default flag value and IndexQuerier type. * Remove additional mode field and reuse it from cfg. * Remove redundant service init. * Add sanity check for IndexGateway client constructor. * Move mode assigning to initStore method. * Reorder IndexGateway constructor. * Rewrite indexClient chunk.IndexClient as querier Index.Querier. * Fix flag registration for IndexGateway server. - In a previous PR I changed how it works and forgot to update how the flag registration occurs. * Fix flag registration for test. * Keep only one reference to indexQuerier. * Add guard-clause on IndexGatewayRing service. - Without this, we would be initializing ring-related things even if the index gateway is in simple mode. * Move IndexGatewayClientCfg to gateway_client file. * Update CHANGELOG.md for `IndexGateway` support for `RingMode` Signed-off-by: JordanRushing <rushing.jordan@gmail.com> * Update GatewayClient to use dskit tenant package Signed-off-by: JordanRushing <rushing.jordan@gmail.com> * Add listenport configuration for IndexGateway and Ring Signed-off-by: JordanRushing <rushing.jordan@gmail.com> * Make IndexGateway replication factor configurable. - Add `replication_factor` flag to the IndexGateway config struct - Modify Index Gateway ring config struct to be inline with a new struct, since it doesn't expose a replication factor config - Modify dynamic config wrapper to reuse a common replication factor on the Index Gateway ring * Randomize replication set access. - If we don't randomize access, we'll always access same Index Gateway instances in same order for the same tenant * Remove unwanted merge HEAD tags. * Move away from stores/chunk package. * Pass util_log in factory. * Change index gateway client ring to ignore replicas. - This is accomplished by using `NewIgnoreUnhealthyInstancesReplicationStrategy` - It is already done by the server * Refactor where the common replication factor is applied. * Housekeeping config_wrapper IndexGateway configs. - Remove unnecessary/wrong comments - Only set replication factor at a single place Co-authored-by: Dylan Guedes <djmgguedes@gmail.com>		3 years ago
