From: Vladislav Shpilevoy <v.shpilevoy@tarantool.org> To: tarantool-patches@dev.tarantool.org, olegrok@tarantool.org Subject: [Tarantool-patches] [PATCH vshard 0/7] Router extended discovery Date: Fri, 1 May 2020 02:16:27 +0200 [thread overview] Message-ID: <cover.1588292014.git.v.shpilevoy@tarantool.org> (raw) Goal of the patchset - solve the problem of routers downloading buckets from storages in too big chunks, making storages waste seconds of TX thread time, when they need to return a million of buckets without yields. Additionally it was asked to allow to stop discovery after all buckets are already discovered by router. For that a new configuration option is introduced and a public function.
