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.

Robert Fratto	d34b1f7450	ingester: support chunk transfers on ingester shutdown. This commit introduces chunk transfers, borrowing the mechanism from Cortex's implementation: when an ingester is shut down with claim on rollout enabled, the ingester will find a pending ingester and transfer all of its chunks to it.	6 years ago
Cyril Tovena	3346ce1b40	Storage memory improvement (#713 ) * add benchmark for storage queries * improve iterator to load only on next * fix memory retained by lazy chunks * reverse backward lazy iterator	6 years ago
Sandeep Sukhani	2a8a03795a	Improvements in live tailing of logs (#541 ) * Improvements in live tailing of logs Instead of polling for new logs, a grpc stream is opened between ingester and querier to get live logs Querier reconnects to disconnected or newly added ingesters * Added more comments to code for live log tailing * Some code refactoring in live log tailing * handling delayfor in logcli, max delayfor to be 5 seconds * some changes in tail response in live tailing * Fixed issue with stopping ingesters gracefully when live tailing is being used * Added tests for tailer in querier * Live tailing made logql compatible, some code refactoring suggested in PR	6 years ago
Ed	fe53924ff8	using the timestamp from the log file might lead to undesired behavior as it could be way in the past or future depending on the clock for the source system generating the logs. Given that it's compared to the servers time.Now() when looking for idle chunks it's probably best to use the server time when setting the value. (#546 )	6 years ago
