>
> For clusters using small compression chunk size and terabytes of data, the 
> streaming plan calculations will instantiate hundreds of millions of 
> compressionmetadata$chunk objects, which will create unreasonable amounts of 
> heap pressure. Rather than instantiating all of those at once, streaming 
> should instantiate only as many as needed for a single file per table at a 
> time.
