Hi, We experienced a crash on our production cluster following a massive wide row read.
A client tried to read a wide row (~4GB of raw data) without specifying any slice condition, which resulted in the crash of multiple nodes (as many as the replication factor) after long garbage collections. We know that wide rows should not be that big, but it is not the topic here. My question is the following: Is it possible to prevent Cassandra from OOM'ing when a client does this kind of requests? I'd rather have an error thrown to the client than a multi-server crash. Our config: Cassandra 2.0.10, requested using Thrift. Kévin
