I have a question regarding the performance of BigQueryIO
DynamicDestinations.
In my use case, I need write the data to hundreds of different tables in
different projects(same region). And the data volume for each table is
quite different which means the data is highly skewed. I observe that the
write performance is very very bad(10x slower) compare if I write all the
data into just one table. All the tables are in same schema
