 * `'maxOpenFiles'` *(number, default: `1000`)*: The maximum number of files that LevelDB is allowed to have open at a time. If your data store is likely to have a large working set, you may increase this value to prevent file descriptor churn. To calculate the number of files required for your working set, divide your total data by 2MB, as each table file is a maximum of 2MB. 
 
-* `'blockRestartInterval'` *(number, default: `16`)*: The number of entries before restarting the "delta encoding" of keys within blocks. Each "restart" point stores the full key for the entry, between restarts, the common prefix of the keys for those entries is omitted. Restarts are similar to the concept of keyframs in video encoding and are used to minimise the amount of space required to store keys. This is particularly helpful when using deep namespacing / prefixing in your keys.

 ### leveldown#batch(operations[, options], callback)
-<code>batch()</code> is an instance method on an existing database object. Used for very fast bulk-write operations (both *put* and *delete*). The `operations` argument should be an `Array` containing a list of operations to be executed sequentially, although as a whole they are performed as an atomic operation inside LevelDB. Each operation is contained in an object having the following properties: `type`, `key`, `value`, where the *type* is either `'put'` or `'del'`. In the case of `'del'` the `'value'` property is ignored. Any entries with a `'key'` of `null` or `undefined` will cause an error to be returned on the `callback`. Any entries where the *type* is `'put'` that have a `'value'` of `undefined`, `null`, `[]`, `''` or `new Buffer(0)` will be stored as a zero-length character array and therefore be fetched during reads as either `''` or `new Buffer(0)` depending on how they are requested.
