-p. A shard is flushed to local disk based on number of operations accumulated in translog. It can be controled using the @index.translog.flush_threshold@ setting (defaults to @5000@).
+p. Each shard has a transaction log or write ahead log associated with it. It allows to guarantee that when an index/delete operation occurs, it is applied atomically, while not "committing" the internal lucene index for each request. A flush ("commit") still happens based on several parameters:
+
+|_. Setting |_. Description |
+|index.translog.flush_threshold_ops|After how many operations to flush. Defaults to @20000@.|
+|index.translog.flush_threshold_size|Once the translog hits this size, a flush will happen. Defaults to @500mb@.|
+|index.translog.flush_threshold_period|The period with no flush happening to force a flush. Defaults to @60m@.|
