Riak KV 2.9.0 - Release - Patch2
Patched for issues:
This resolves an issue whereby sending a burst of very large objects to Riak with a leveled backend would result in the leveled consuming far higher than expected binary memory. This memory would not be released, unless PUTs continue to be received (to trigger a write to file). This could cause particular problems during transfers, when the highest bucket name contained a large number of large objects.
