> The implementation of {{AzureJournalWriter#batchWriteLines}} (inside {{{}AzureJournalFile{}}}) is very inefficient. If the batch size is high, it can take minutes to complete. The issue is that {{batchWriteLines()}} simply delegates to {{{}writeLine(){}}}, which uploads each single line (and metadata) to the blob.
> We should implement {{batchWriteLines() }}by uploading multiple lines in one call.
