Ed Schouten	bb724f1bef	Deprecate DeduplicateSeriesSet() in favor of NewMergeSeriesSet(). Federation makes use of dedupedSeriesSet to merge SeriesSets for every query into one output stream. If many match[] arguments are provided, many dedupedSeriesSet objects will get chained. This has the downside of causing a potential O(nk) running time, where n is the number of series and k the number of match[] arguments. In the mean time, the storage package provides a mergeSeriesSet that accomplishes the same with an O(nlog(k)) running time by making use of a binary heap. Let's just get rid of dedupedSeriesSet and change all existing callers to use mergeSeriesSet.	7 years ago

Tom Wilkie	48a7a00a38	Fast path the merge querier (#3358 ) * Fast path the merge querier such that it is completely removed from query path when there is no remote storage. * Add NoopQuerier * Add copyright notice. * Avoid global, use a function.	7 years ago

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	9ef8518b37	Remove "package remote" garbage from license headers (#3304 )	7 years ago
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	7 years ago

Tom Wilkie	96e25adc8d	Introduce 'primary' storage in fanout, and have Add return the ref from the primary. Also, ensure all append batches are rolled back when a commit or rollback fails.	7 years ago
