apply correct formatting to the text or insert special characters by recognizing particular character usage. • Hyphenation: You can use the hyphenation feature to insert hyphens in words that are too long free, fuzzy and bezier • Transformation tools such as rotate, scale, shear and flip • Tile-based memory management so that the image size is limited only by available disk space • Multiple undo/re-do Copy 4. The selected files now appear in the project window. You can also view the estimated disc usage once these files are written to the disc at the bottom of the project window. Based on this data,

support eBay scale ■ Proxy config convergence time (CDS, EDS, LDS, RDS push times) ■ Resource usage (CPU, memory, etc.) ○ Secondary Goal ■ Fine-tune configuration params - debounce interval, push concurrency Testing: Results ● Default wide-open egress sidecar configuration does not scale ○ Results in high memory usage & convergence times since each sidecar knows about all services in the cluster ○ Disabled egress from single Pilot instance to 0 - 3,000 sidecars < 1 second ○ Pilot CPU & memory within acceptable limits: < 10 cores, 25 GB memory ○ Pilot can scale horizontally ● Need to tune PILOT_DEBOUNCE_AFTER, PILOT_DEBOUNCE_MAX
