The functions in this file are very hard to follow (aside from being undocumented) often because the one input parameter `request` is last, not first! In many cases there are several input parameters and they all appear before the sole input parameter.

According to the Google Style Guide, input-only parameters should be ordered first, before in/out or output parameters.

Functions (~15, incorrectly ordered params in parentheses):

• insertBatchAndHandleErrors (OperationSource)
• performUpdate(curOp, updateRequest)
• performSingleUpdateOp(containsDotsAndDollarsField)
• performTimeseriesInsert(batch)
• performTimeseriesUpdate(batch)
• tryPerformTimeseriesBucketCompression(request)
• commitTimeseriesBucketsAtomically(request)
• rebuildOptionsWithGranularityFromConfigServer(timeseriesOptions)
• insertIntoBucketCatalog(request)
• performOrderedTimeseriesWritesAtomically(request)
• performUnorderedTimeseriesWrites(request)
• performUnorderedTimeseriesWritesWithRetries(request)
• performOrderedTimeseriesWrites (request)
• explainUpdate(updateRequest)
• explainDelete(deleteRequest)
