What if we tell you that there is a sure way to get IST not SST for node rejoins? You can guarantee that a new node rejoins using IST. Sound interesting? Keep reading.
Normally when a node is taken out of the cluster for a short period of time (for maintenance or shutdown), gcache on other nodes of the cluster help donate the missing write-set(s) when the node rejoins. This approach works if you have configured a larger gcache, or the downtime is short enough. Both approaches aren’t good, especially for a production cluster. Also, a larger gcache for the server lifetime means blocking larger disk-space when the same job can be done with relative smaller disk-space.
Re-configuring gcache, on a potential DONOR node before downtime requires a node …[Read more]
