This variable is used to set the default size limit of ingest requests after content-encoding has been applied.

The value is expressed in bytes.

The default value of 32 MB limits the size of ingest requests and rejects oversized requests. If the request is compressed within HTTP, then this restricts the size after decompressing.

Alternatively, the default can be applied via the dynamic configuration MaxIngestRequestSize. The recommendation is to set this size fairly low, such as 10 - 100 MB; however, be aware that doing so may break existing integrations that rely on ingesting very large payloads. Use the new request log field decodedContentLength to find what range of sizes to expect for existing clusters.
