+      Zookeeper also allows you to add a "chroot" path which will make all kafka data for this cluster appear under a particular path.
+      This is a way to setup multiple Kafka clusters or other applications on the same zookeeper cluster. To do this give a connection
+      string in the form hostname1:port1,hostname2:port2,hostname3:port3/chroot/path which would put all this cluster's data under the
+      path /chroot/path. Note that you must create this path yourself prior to starting the broker and consumers must use the

Note that this is the limit per-partition so multiply by the number of partitions to get the total data retained for the topic.

+    <value>10485760</value>
+    <description>
+      The maximum size in bytes we allow for the offset index for each log segment. Note that we will always pre-allocate a
+      sparse file with this much space and shrink it down when the log rolls. If the index fills up we will roll a new log segment
+      even if we haven't reached the log.segment.bytes limit.

+  </property>
+  <property>
+    <name>log.index.interval.bytes</name>
+    <value>4096</value>
+    <description>
+      The byte interval at which we add an entry to the offset index. When executing a fetch request the server must do a linear scan for up to this many bytes to find the correct position in the log to begin and end the fetch. So setting this value to be larger will mean larger index files (and a bit more memory usage) but less scanning. However the server will never add more than one index entry per log append (even if more than log.index.interval worth of messages are appended). In general you probably don't need to mess with this value.
