I ran the backfill branch on yesterday's nightly pings and some of the new fields are all null:
histogram_content_memory_distribution_among_content
histogram_content_memory_heap_committed_unused
histogram_content_memory_total
histogram_content_memory_unique
histogram_gpu_memory_distribution_among_content
histogram_gpu_memory_heap_allocated
histogram_gpu_memory_heap_committed_unused
histogram_gpu_memory_resident_fast
histogram_gpu_memory_total
histogram_gpu_memory_unique
histogram_gpu_memory_vsize
histogram_gpu_memory_vsize_max_contiguous
histogram_parent_memory_heap_committed_unused

Can you verify the names and whether we should be seeing data in these histograms? If these are just that rare or not being recorded properly, I vote we remove them as columns for the backfill and file bugs for the owners if warranted.

These have been automatically added through the `MainPing.histogramsToRow` function. It looks like the gpu rows should not be there and may be a bug with com.mozilla.telemetry.metrics.Histogram. The content fields look like they have mistakenly been specified to be overly broad. For example, MEMORY_TOTAL is specified for the parent and content process [1] but is only recorded in the parent process [2].
