+============
+Setting `xpack.reporting.csv.maxSizeBytes` much larger than the default 10 MB limit has the potential to negatively affect the
+performance of {kib} and your {es} cluster. There is no enforced maximum for this setting, but a reasonable maximum value depends
+on multiple factors:
+
+* The `http.max_content_length` setting in {es}.
+* Network proxies, which are often configured by default to block large requests with a 413 error.
+* The amount of memory available to the {kib} server, which limits the size of CSV data that must be held temporarily.

+For information about {kib} memory limits, see <<production, using {kib} in a production environment>>.
