Dylan Guedes 440fb7d74c Loki: Modifies TableManager to use IndexGateway ring (#5972) ... * Add two metrics to the IndexGateway. - Add a new `query_readiness_duration_seconds` metric, that reports query readiness duration of a tablemanager/index gateway instance. We should use it later to report performance against the ring mode - Add a new `usersToBeQueryReadyForTotal` metric, that reports number of users involved in the query readiness operation. We should use it later to correlate number of users with the query readiness duration. * Remove `usersToBeQueryReadyForTotal`. - It will report all users always for now, so it isn't too helpful the way it is. * Rename metric help text to not mislead people. * Log queryReadiness duration. * Fix where log message and duration and triggered. * Add two metrics to the IndexGateway. - Add a new `query_readiness_duration_seconds` metric, that reports query readiness duration of a tablemanager/index gateway instance.

Co-authored-by: JordanRushing <rushing.jordan@gmail.com> * Join users list in a single string. - This is necessary since go-kit doesn't support array type. * Tweak queryReadiness log messages. - As suggested by Ed on https://github.com/grafana/loki/pull/5972#discussion_r859734129 and https://github.com/grafana/loki/pull/5972#discussion_r859736072 * Implement new RingManager. - Adds a new entity to indexgateway named RingManager, responsible for managing the ring and the lifecycler used by the indexgateway. The ringManager is guaranteed to be initiatiated before the Shipper and before the IndexGateway. - Remove the readiness logic from the IndexGateway. - Pass the RingManager as the TenantBoundaries implementation of the Shipper * Return non-empty ringmanager for all modes. * Fix lint regarding error not being check. * Fix lint due to wrong import order. * Implement support for client and server mode for the ring manager. * Fix ring manager services registration. * Add option to configure whether or not to log gateway requests. * Check if IndexGateway is enabled instead of active. * Tune RingManager behavior. - Instantiate ring buffers inside IsAssignedKey instead of reusing same buffer to avoid issues with concurrency. - Remove unnecessary details from IndexGateway mode docs. - Return error when wrongly instantiating a RingManager when IndexGateway is in simple mode. * Rewrite `TenantInBoundaries` as a func instead of interface. * Fix lint. - Fix YAML tag - Remove else clause * Use distributor instead of querier in test. - Since the querier needs to wait for the index gateway ring, it isn't suitable for this test anymore. * Add ring mode guard clause. * Return code erased by mistake. * Rename TenantInBoundaries to IndexGatewayOwnsTenant. * Log len of users instead of all of them to avoid log msgs. * Add docstrings to new public functions. * Apply suggestions from code review Document that tenant filtering is only applied during query readiness. Co-authored-by: Sandeep Sukhani <sandeep.d.sukhani@gmail.com> * Modify IsAssignedKey to expect address directly instead of lifecycler. - Also removes HasDedicatedAddress, since it isn't necessary anymore * Log error message when IsInReplicationSet fails. * Modify IsAssignedKey to return true by default. * Remove wrong assigning of Service for clientMode. * Log gateway requests before error checks. * Remove unnecessary endpoint registration. * Fix lint. * Update pkg/util/ring.go Co-authored-by: Sandeep Sukhani <sandeep.d.sukhani@gmail.com> Co-authored-by: JordanRushing <rushing.jordan@gmail.com> Co-authored-by: Sandeep Sukhani <sandeep.d.sukhani@gmail.com>		3 years ago
