<p> Each instance of RocksDB allocates off-heap memory for a block
cache, index and filter blocks, and memtable (write buffer). Critical configs
(for RocksDB version 4.1.0) include
<code class="docutils literal"><span
class="pre">block_cache_size</span></code>, <code class="docutils
literal"><span class="pre">write_buffer_size</span></code> and <code
class="docutils literal"><span
class="pre">max_write_buffer_number</span></code>. These can be specified
through the
- <code class="docutils literal"><span
class="pre">rocksdb.config.setter</span></code> configuration.</li>
+ <code class="docutils literal"><span
class="pre">rocksdb.config.setter</span></code> configuration.</p>

because the default allocator may lead to increased memory consumption.
+ To change the memory allocator to <code>jemalloc</code>, you need to
set the an environment variable before you start your Kafka Streams
application:</p>
