+> #### Use gzip to compress a large query response
+> 
+> To compress the query response, set the `Accept-Encoding` header to `gzip`.
+> This saves network bandwidth, but increases server-side load.
+> 
+> We recommend only using gzip compression on responses that are larger than 1.4 KB.
+> If the response is smaller than 1.4 KB, gzip encoding will always return a 1.4 KB
+> response, despite the uncompressed response size.
+> 1500 bytes (~1.4 KB) is the maximum transmission unit (MTU) size for the public
+> network and is the largest packet size allowed at the network layer.
