Hey, not sure, if I made my point clear here: The minimum_master_nodes is an important setting, if a master node election is about to happen (this is not checked for each write of a document). The write_consistency is a check, when a document is about to be stored. Also note, that this check happens, before the data is written to the primary shard. (This is not checked during a master election).
Hope it makes more sense now. ---Alex On Thu, Feb 6, 2014 at 6:35 PM, Mohit Anchlia <mohitanch...@gmail.com>wrote: > So the checks are made in that order? 1) enough master nodes are available > 2) Within that cluster decide how many replicas would acknowledge success > before returning back to the client > > In other words just by having write_consistency set to quorum it doesn't > gurantee protection against split brain. > > On Thu, Feb 6, 2014 at 1:30 AM, Alexander Reelsen <a...@spinscale.de>wrote: > >> Hey, >> >> these two settings to not have a lot in common, wondering in what context >> you see them the same. >> >> minimum_master_nodes setting is only about the count of available nodes, >> which are eligible to become a master in order to actually have an existing >> master in a cluster. >> write_consistency qourum is actually a check when a document is indexed >> (and not about the nodes in a cluster) in order to decide if the document >> should be written at all (before it is actually indexed) >> >> See >> http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/modules-discovery-zen.html#master-election >> and >> http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/docs-index_.html#index-consistency >> >> Does that make sense, is this more clear now? >> >> >> --Alex >> >> >> >> On Mon, Feb 3, 2014 at 11:19 PM, Mohit Anchlia <mohitanch...@gmail.com>wrote: >> >>> How does minimum_master_nodes differ from action.write_consistency? >>> Would setting write_consistency to quorum help when minimum_master is not >>> set appropriately? >>> >>> On Thu, Jan 16, 2014 at 6:08 AM, Norberto Meijome <num...@gmail.com>wrote: >>> >>>> Gotcha, my bad. >>>> On 17/01/2014 12:43 AM, "joergpra...@gmail.com" <joergpra...@gmail.com> >>>> wrote: >>>> >>>>> minimum_master_nodes is a dynamic cluster setting, that means, it can >>>>> be set via cluster update API. >>>>> >>>>> Jörg >>>>> >>>>> -- >>>>> You received this message because you are subscribed to the Google >>>>> Groups "elasticsearch" group. >>>>> To unsubscribe from this group and stop receiving emails from it, send >>>>> an email to elasticsearch+unsubscr...@googlegroups.com. >>>>> To view this discussion on the web visit >>>>> https://groups.google.com/d/msgid/elasticsearch/CAKdsXoHFgi5Wj%2Bz0P%2Bq3AJj55bTjaNhjGAzj_DHPmVfq6iRpBQ%40mail.gmail.com >>>>> . >>>>> For more options, visit https://groups.google.com/groups/opt_out. >>>>> >>>> -- >>>> You received this message because you are subscribed to the Google >>>> Groups "elasticsearch" group. >>>> To unsubscribe from this group and stop receiving emails from it, send >>>> an email to elasticsearch+unsubscr...@googlegroups.com. >>>> To view this discussion on the web visit >>>> https://groups.google.com/d/msgid/elasticsearch/CACj2-4JfuGA4wAmTCjMdo2T%2B4cuY96EV1EN3Grc-pDMt%3D3xX%3DA%40mail.gmail.com >>>> . >>>> >>>> For more options, visit https://groups.google.com/groups/opt_out. >>>> >>> >>> -- >>> You received this message because you are subscribed to the Google >>> Groups "elasticsearch" group. >>> To unsubscribe from this group and stop receiving emails from it, send >>> an email to elasticsearch+unsubscr...@googlegroups.com. >>> To view this discussion on the web visit >>> https://groups.google.com/d/msgid/elasticsearch/CAOT3TWrGJHi_R_WXquKD-GmYv_fojs23h%2B-rBs-NZxNSznQwmQ%40mail.gmail.com >>> . >>> >>> For more options, visit https://groups.google.com/groups/opt_out. >>> >> >> -- >> You received this message because you are subscribed to the Google Groups >> "elasticsearch" group. >> To unsubscribe from this group and stop receiving emails from it, send an >> email to elasticsearch+unsubscr...@googlegroups.com. >> To view this discussion on the web visit >> https://groups.google.com/d/msgid/elasticsearch/CAGCwEM-4K9f6dDScGMS75nZU-LYBvdQ5opi7k-nVBi6w%3DwstyA%40mail.gmail.com >> . >> >> For more options, visit https://groups.google.com/groups/opt_out. >> > > -- > You received this message because you are subscribed to the Google Groups > "elasticsearch" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to elasticsearch+unsubscr...@googlegroups.com. > To view this discussion on the web visit > https://groups.google.com/d/msgid/elasticsearch/CAOT3TWp6QV%2B8ySSY7PYLBiz2DEE%2B-xRvU0SnUiORJdRc1r85Fg%40mail.gmail.com > . > > For more options, visit https://groups.google.com/groups/opt_out. > -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
