VariableMAX_INGEST_REQUEST_SIZE
DescriptionSize limit of ingest requests after content-encoding has been applied
Default1 GB

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