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

Robert Fratto	2cb3c82cc8	pkg/ingester: prevent shutdowns from processing during joining handoff ... This commit fixes a race condition where an ingester that is shut down during the joining handoff (i.e., receiving chunks from a leaving ingester before claiming its tokens) hangs and can never shut down cleanly. A shutdown mutex is implemented which is obtained at the start of the handoff process and released after the handoff process completes. This race condition also prevented the leaving ingester from completing its shutdown, since it waits for the joining ingester to claim the tokens. This means that if a brand new ingester is shut down, it will always have finished receiving chunks from the previous leaving ingester and have finished obtaining the tokens from the ingester attempting to leave.	6 years ago

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.	7 years ago
