Review comment:
Please note that `WriteBatch` is atomic transaction.
Large `WriteBatch` could leads to contention and high error rates.
We are working on launching a batchWrite API for non-atomic data ingestion
use cases. Before it gets launched, the next best option is writing each
document separately.
(BTW, we have a max 500 write per commit limit.)
