Fix multi-tenant exemplar matchers #5554

Merged

The exemplar proxy synthesizes a query based on PromQL expression matchers
and individual store's label sets. When a store has multiple label sets
with same label names but different values (e.g. multitenant Receivers),
each exemplar matcher will be repeated once for each label set. Because of this,
a receiver hosting 200 tenants can get the same exemplar matcher 200 times. This leads
to the underlying stores slowing down and timing out when asked for exemplars.

This commit modifies the exemplar proxy to deduplicate matchers and only send
a matcher once to an underlying store.

Fixes #5444

Nice. I think the change makes sense. Just some nits only.

* Implement GRPC query API (#5250)

With the current GRPC APIs, layering Thanos Queriers results in
the root querier getting all of the samples and executing the query
in memory. As a result, the intermediary Queriers do not do any
intensive work and merely transport samples from the Stores to the
root Querier.

When data is perfectly sharded, users can implement a pattern where
the root Querier instructs the intermediary ones to execute the queries
from their stores and return back results. The results can then be
concatenated by the root querier and returned to the user.

In order to support this use case, this commit implements a GRPC API
in the Querier which is analogous to the HTTP Query API exposed
by Prometheus.

* Change error cleanup in objstore.DownloadDir to delete files not directories

Dst is always a directory. If any file after the first fails to download,

This commit extends endpointsets with a GetQueryAPIClients method
which returns Query API clients to all components which support
this API.

* groupcache: reduce log severity (#5323)

Sometimes certain operations can fail with some error(-s) being expected
e.g. a deletion marker might or might not exist. Thus, these log lines
could get triggered even though nothing bad is happening. Since the
expected errors are known only at the very end, near the call site, and
because `error`s are already logged in other places, and because these
Fetch()/Store() functions are working in best-effort scenario, I propose
reducing the severity of these log lines to `debug`.

* Improve ketama hashring replication (#5427)

With the Ketama hashring, replication is currently handled by choosing
subsequent nodes in the list of endpoints. This can lead to existing nodes
getting more series when the hashring is scaled.

This commit changes replication to choose subsequent nodes from the hashring
which should not create new series in old nodes when the hashring is scaled.

* Implement query sharding

This commit implements query sharding for grouping PromQL expressions.

Sharding is initiated by analyzing the PromQL and extracting
grouping labels. Extracted labels are propagated down to Stores which
partition the response by hashmoding all series on those labels.

If a query is shardable, the partitioning and merging process will be
initiated by the Query Frontend. The Query Frontend will make N distinct
queries across a set of Queriers and merge the results back before
presenting them to the user.

* Fix multi-tenant exemplar matchers (#5554)

* Fix multi-tenant exemplar matchers

The exemplar proxy synthesizes a query based on PromQL expression matchers
and individual store's label sets. When a store has multiple label sets
with same label names but different values (e.g. multitenant Receivers),
each exemplar matcher will be repeated once for each label set. Because of this,
a receiver hosting 200 tenants can get the same exemplar matcher 200 times. This leads
to the underlying stores slowing down and timing out when asked for exemplars.

This commit modifies the exemplar proxy to deduplicate matchers and only send
a matcher once to an underlying store.
