VariableUNSAFE_RELAX_FEDERATED_PROTOCOL_VERSION_CHECK
Introduced Version1.124
Description Permits version discrepancy across clusters in Multi-Cluster Search, provided that the versions are compatible at the protocol level.
Defaultfalse

In LogScale Multi-Cluster Search, because the multi-cluster protocol is not compatible across versions of LogScale, the exact same version of LogScale must be run on all clusters, with the system checking that the versions match. However, for cases where the exact version match is prohibitively strict, it is possible to bypass this rule by setting the following configuration:

ini
UNSAFE_RELAX_FEDERATED_PROTOCOL_VERSION_CHECK=true

It will allow for version discrepancy across clusters, provided that the versions are compatible at the protocol level.

The whole implementation as well as this workaround configuration are explained in more detail at Multi-Cluster Version Support.
