What Drags Down Throughput in GBase 8a Bulk Loading — and Where to Look First

When loading large volumes into a GBase 8a database cluster, stability matters more than peak throughput. Common bottlenecks include poorly balanced parallelism, file chunking, excessive small files, error-row handling, and node load. To optimize, consider file organisation, node parallelism, and error handling. Use community-recommended values for gcluster_loader_max_data_processors and gbase_loader_parallel_degree. Don't mix big-file and small-file optimisation into one recipe.
