The following are limitations specific to the
NDBCLUSTER storage engine:
Machine architecture. All machines used in the cluster must have the same architecture. That is, all machines hosting nodes must be either big-endian or little-endian, and you cannot use a mixture of both. For example, you cannot have a management node running on a PowerPC which directs a data node that is running on an x86 machine. This restriction does not apply to machines simply running mysql or other clients that may be accessing the cluster's SQL nodes.
sql_log_binhas no effect on data operations; however, it is supported for schema operations.
NDB Cluster cannot produce a binary log for tables having
BLOBcolumns but no primary key.
Only the following schema operations are logged in a cluster binary log which is not on the mysqld executing the statement:
Schema operations (DDL statements) are rejected while any data node restarts.
