Method Detail

runBatch

void runBatch(BatchRunner.Batch batch)

Provides support for batching configuration changes.

It is guaranteed that

• All configuration reads and writes in a batch are performed within a single transaction, i.e. the changes are atomic and performed in READ COMMITTED isolation
• When this method is called, an ongoing transaction (in case there is one) will be SUSPENDED. The batch will ALWAYS be executed in a SEPARATE transaction.
• At most ONE batch is executed at the same time in the whole cluster (synchronized with a database lock)

Parameters:

batch - Configuration batch change to execute
