* [Tarantool-patches] [PATCH] replication: removing anonymous replicas from synchro quorum
@ 2021-09-20 19:59 Yan Shtunder via Tarantool-patches

From: Yan Shtunder via Tarantool-patches @ 2021-09-20 19:59 UTC (permalink / raw)
  To: sergepetrenko, shemeneval; +Cc: tarantool-patches, Yan Shtunder

Transactions have to committed after they reaches quorum of "real"
cluster members. Therefore, anonymous replicas don't have to
participate in the quorum.

Closes #5418

* [Tarantool-patches] [PATCH] replication: removing anonymous replicas from synchro quorum

  To: sergepetrenko, shemeneval; +Cc: tarantool-patches, Yan Shtunder

Transactions have to committed after they reaches quorum of "real"
cluster members. Therefore, anonymous replicas don't have to
participate in the quorum.

Closes #5418
