Cyril Tovena	55b91fc793	Fixes head chunk iterator direction. (#3383 ) * Fixes head chunk iterator direction. For backward queries, since LogQL parser we are using a heapIterator in the headchunk to re-order properly entries. But we also reverse all iterators in the memchunk code, even the headchunk which causes reversal of already reversed entries. This PR skips reversal of the headchunk. Fixes #3345 Fixes #3208 This has for side effects: - when using replication you would not dedupe data properly anymore, since the data is not correctly ordered accross batches. - when using limit it would miss entries.

Peter Štibraný	dca244f7aa	pkg/ingester: added sync period flags SyncPeriod can be used to tell ingesters to cut chunks early (before they are full) to synchronize ingesters so that they put the same data into the new chunks. If they do, they generate fully equal chunks and then they don't need to store them. To avoid very small chunks, additional parameter is added: -ingester.sync-min-utilization. When set to eg. 0.5, chunk must be at least 50% full (utilization) in order to be cut early for sync purposes. Signed-off-by: Peter Štibraný <peter.stibrany@grafana.com>	6 years ago
