Drill provides many configuration options that you can enable, disable, or modify. Modifying certain configuration options can impact Drill performance. Many of the configuration options reside in the `drill-env.sh` script and the `drill-override.conf` configuration file located in the `$DRILL_HOME/conf` directory. Drill loads these files from `/etc/drill/conf`, if it exists. Otherwise, Drill loads the files from the `$DRILL_HOME/conf` directory.
-{% include startnote.html %}As of Drill 1.8, default Drill settings reside in `$DRILL_HOME/bin/drill-config.sh`. You can override many settings by creating an entry in `$DRILL_HOME/conf/drill-env.sh`. The file includes descriptions of the options that you can set.{% include endnote.html %}
+{% include startnote.html %}As of Drill 1.8, most of the system options listed below are set in `$DRILL_HOME/conf/drill-override.conf`. Settings controlled through environment variables reside in `$DRILL_HOME/bin/drill-config.sh`. You can create an entry in `$DRILL_HOME/conf/drill-env.sh` to override many of the settings in `drill-config.sh`.

The sys.options table contains information about system and session options. The sys.boot table contains information about Drill start-up options. The section, ["Start-up Options"]({{site.baseurl}}/docs/start-up-options), covers how to configure and view key boot options. The following table lists the system options in alphabetical order and provides a brief description of supported options.

| Operator | Description |
|----------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| HashToRandomExchange | A HashToRandomExchange gets an input row, computes a hash value on the distribution key, determines the destination receiver based on the hash value, and sends the row in a batch operation. The join key or aggregation group-by keys are examples of distribution keys. The destination receiver is a minor fragment on a destination node. |
-| HashToMergeExchange | A HashToMergeExchange is similar to the HashToRandomExchange operator, except that each destination receiver mergers incoming streams of sorted data received from a sender. |
+| HashToMergeExchange | A HashToMergeExchange is similar to the HashToRandomExchange operator, except that each destination receiver merges incoming streams of sorted data received from a sender. |
| UnionExchange | A UnionExchange is a serialization operator in which each sender sends to a single (common) destination. The receiver \u201cunions\u201d the input streams from various senders. |
| SingleMergeExchange | A SingleMergeExchange is distribution operator in which each sender sends a sorted stream of data to a single receiver. The receiver performs a Merge operation to merge all of the incoming streams. This operator is useful when performing an ORDER BY operation that requires a final global ordering. |
-| BroadcastExchange | A BroadcastExchange is a distrubtion operation in which each sender sends its input data to all N receivers via a broadcast. |
+| BroadcastExchange | A BroadcastExchange is a distribution operation in which each sender sends its input data to all N receivers via a broadcast. |
| UnorderedMuxExchange | An UnorderedMuxExchange is an operation that multiplexes the data from all minor fragments on a node so the data can be sent out on a single channel to a destination receiver. A sender node only needs to maintain buffers for each receiving node instead of each receiving minor fragment on every node. |
