Maxim, In general rebalanceDelay is used to delay/disable rebalance then topology is changed. Right now we have BLT to avoid unnecesary rebalancing when topology is changed. If a node left from cluster topology no rebalancing happens until the node explicitly removed from baseline topology.
I would like to know real world scenarios which can not be covered by BLT configuration. ср, 12 февр. 2020 г. в 15:16, Maxim Muzafarov <mmu...@apache.org>: > Alexey, > > > All scenarios where rebalanceDelay has meaning are handled by baseline > topology now. > > Can you, please, provide more details here e.g. the whole list of > scenarios where rebalanceDelay is used and how these handled by > baseline topology? > > Actually, I doubt that it covers exactly all the cases due to > rebalanceDelay is a "per cache group property" rather than "baseline" > is meaningful for the whole topology. > > On Wed, 12 Feb 2020 at 12:58, Alexei Scherbakov > <alexey.scherbak...@gmail.com> wrote: > > > > I've meant baseline topology. > > > > ср, 12 февр. 2020 г. в 12:41, Alexei Scherbakov < > > alexey.scherbak...@gmail.com>: > > > > > > > > V.Pyatkov > > > > > > Doesn't rebalance topology solves it ? > > > > > > ср, 12 февр. 2020 г. в 12:31, V.Pyatkov <vldpyat...@gmail.com>: > > > > > >> Hi, > > >> > > >> I am sure we can to reduce this ability, but do not completely. > > >> We can use rebalance delay for disable it until manually triggered. > > >> > > >> CacheConfiguration#setRebalanceDelay(-1) > > >> > > >> It may helpful for cluster where can not allow performance drop from > > >> rebalance at any time. > > >> > > >> > > >> > > >> -- > > >> Sent from: http://apache-ignite-developers.2346864.n4.nabble.com/ > > >> > > > > > > > > > -- > > > > > > Best regards, > > > Alexei Scherbakov > > > > > > > > > -- > > > > Best regards, > > Alexei Scherbakov > -- Best regards, Alexei Scherbakov
