Anton Kalashnikov commented on IGNITE-12600:
--------------------------------------------

[~ilyak] Auto-adjust configuration stored in distributed megastore so it's 
configured for the whole cluster rather than one node. If the user has a 
problem like you described above it's mean that the user has already started 
cluster so the user can disable auto-adjust via java API, control.sh or mxbean.
And just note: IgniteConfiguration, in this case, doesn't make any sense 
because the auto-adjust is settings of the cluster rather than the node so if 
we add it to IgniteConfiguration it'll complicate current logic due to extra 
handling of different settings of different nodes.

> Baseline auto-adjust makes it impossible to assemble mixed persistence 
> clusters

> If you try to start a cluster of two nodes, where A only has default 
> non-persistent region, and B also has a persistent non-default region, it 
> will fail with:
> {code}
> Caused by: class org.apache.ignite.spi.IgniteSpiException: Joining 
> persistence node to in-memory cluster couldn't be allowed due to baseline 
> auto-adjust is enabled and timeout equal to 0
> {code}
> However, there seem to be no configuration settings to actually disable this.
