The Covid situation resulted in exponential increase in search & ingestion volume causing cluster availability issues. My team and I worked ~3 months to get ourselves prepared for the peak traffic day (Retail Friday - 2020) at PayPal. Right from hardware, tuning was done at every layer. My team and I are proud of our accomplishment, incident free handling of PayPal holiday traffic and would like share our experience with Elasticsearch community.
