Julius Volz 099df0c5f0 Migrate "golang.org/x/net/context" -> "context" (#3333) 
In some places, where ctxhttp or gRPC are concerned, we still need to use the
old contexts.

Brian Brazil 4a50f547c8 removeLabels needs a pointer to work. (#3326) 2017-10-21 08:29:03 +01:00
Thibault Chataigner bf4a279a91 Remote storage reads based on oldest timestamp in primary storage (#3129) 
Currently all read queries are simply pushed to remote read clients.
This is fine, except for remote storage for wich it unefficient and
make query slower even if remote read is unnecessary.
So we need instead to compare the oldest timestamp in primary/local
storage with the query range lower boundary. If the oldest timestamp
is older than the mint parameter, then there is no need for remote read.
This is an optionnal behavior per remote read client.

Julius Volz f7e8348a88 Re-add contexts to storage.Storage.Querier() (#3230) 
* Re-add contexts to storage.Storage.Querier()

These are needed when replacing the storage by a multi-tenant
implementation where the tenant is stored in the context.

The 1.x query interfaces already had contexts, but they got lost in 2.x.

* Convert promql.Engine to use native contexts

Tom Wilkie ec999ff397 Prevent number of remote write shards from going negative. 
This can happen in the situation where the system scales up the number of shards massively (to deal with some backlog), then scales it down again as the number of samples sent during the time period is less than the number received.

Julius Volz e9476b35d5 Re-add multiple remote writers 
Each remote write endpoint gets its own set of relabeling rules.

This is based on the (yet-to-be-merged)
https://github.com/prometheus/prometheus/pull/2419, which removes legacy
remote write implementations.

Julius Volz beb3c4b389 Remove legacy remote storage implementations 
This removes legacy support for specific remote storage systems in favor
of only offering the generic remote write protocol. An example bridge
application that translates from the generic protocol to each of those
legacy backends is still provided at:

documentation/examples/remote_storage/remote_storage_bridge

See also https://github.com/prometheus/prometheus/issues/10

The next step in the plan is to re-add support for multiple remote
storages.
