>
> Loading {{IndexMetaData}} is a somewhat expensive operation because it may
> deserialize from scan attribute. In following
> {{IndexRegionObserver.preBatchMutateWithExceptions}} method,
> {{IndexMetaData}} is loaded already for line 613, but in
> {{IndexRegionObserver.prepareIndexMutations}} method which is invoked by line
> 639, {{IndexMetaData}} is loaded again, which is unnecessary.
> {code:java}
> 610 public void
> preBatchMutateWithExceptions(ObserverContext<RegionCoprocessorEnvironment> c,
> 611 MiniBatchOperationInProgress<Mutation> miniBatchOp)
> throws Throwable {
> 612 ignoreAtomicOperations(miniBatchOp);
> 613 BatchMutateContext context = new
> BatchMutateContext(this.builder.getIndexMetaData(miniBatchOp).getClientVersion());
> 614 setBatchMutateContext(c, context);
> 615 Mutation firstMutation = miniBatchOp.getOperation(0);
> ....
> 639 prepareIndexMutations(c, miniBatchOp, context, mutations, now);
