Commit Message

Throttle writers while Batch Write and DB Restore (#762)

* Implement throttling while DB restore

DB restore works by reading backup file line by line, creating
batches of entries and writing those batches asynchronously by
calling db.batchSetSync method. In some cases if data is more,
there can be many batches which are not persisted and hence are
present in memory. As there is no throttling now, this can lead
to memory outage and crashing of restore application. This commit
throttles number of batches which can be present in memory.

* Throttle pending transactions in WriteBatch

Currently there is no limit on number of pending transactions(
uncomitted transactions) in WriteBatch. Sometimes this leads to
huge memory consumptions and atlast crashing of Badger. This commit
implements throttling in WriteBatch and hence limits pending
transactions count to a threshold.
