After API keys (19 Oct), this post covers compression on the wire and at rest: negotiation, thresholds, CPU levels, security caveats, static precompress, columnar stores and metrics.

संपीडनधर्मः: A Metrical Codification of Compression (with English glosses)

What this post is about

Compression shrinks payloads and files by spending CPU. Good practice picks the right layer and measures latency impact.

Topics covered

1. Bandwidth and cost pressure
2. Transit vs at-rest
3. HTTP Content-Encoding
4. Skip tiny payloads
5. Compression level CPU
6. Security caveats with secrets
7. Precompressed static assets
8. Columnar analytics ratios
9. Measure ratio/CPU/latency
10. Cache interactions

Sanskrit title

संपीडनधर्मः = saṃpīḍana-dharmaḥ “dharma of compression”.

English

Minimizable; Sanskrit-first.

ग्राह्यम् / Keep

१. negotiate encodings: gzip/br where fit
२. min size threshold: skip tiny bodies
३. level budget: match latency SLO
४. no secret mix care: side-channel awareness
५. precompress static: build pipeline
६. measure three: ratio CPU p95
७. Vary encoding: on shared caches

त्याज्यम् / Avoid

• force max compression on all JSON always
• double-compress images
• enable without latency metrics

पदच्छेदः
बृहत्प्रवाहः यदि असीमः तदा जालं धनं च दह्यते । संपीडनधर्मस्तस्माद् मितमात्रा ॥१॥

Word-for-word

Gloss table

English sense
Compression reduces bytes on the wire and sometimes on disk. It trades CPU for bandwidth and storage.

transit compress vs at-rest भिद्यते । एकं नीतिर् न द्वयोः ॥२॥

Word-for-word

Gloss table

English sense
HTTP Content-Encoding and database/page compression are different layers with different knobs and failure modes.

पदच्छेदः
Content-Encoding gzip br negotiate । double gzip भङ्गाय ॥३॥

Word-for-word

Gloss table

English sense
Negotiate encodings with the client. Avoid double-compression of already compressed images or pre-gzipped assets without care.

पदच्छेदः
small payloads मा नित्यं संपीडय । CPU>bytes लघुषु ॥४॥

Word-for-word

Gloss table

English sense
Below a size threshold compression can cost more latency than it saves. Threshold and skip lists matter.

Context / topic
Topic: when not to compress.

पदच्छेदः
dictionary levels workers CPU बजट् । unlimited level9 latency हन्ति ॥५॥

Word-for-word

Gloss table

English sense
Pick levels that match your latency SLO. Max compression on every request is rarely free.

Context / topic
Topic: CPU budget.

वृत्तमिति: एकादशाक्षराः पादाः।

पदच्छेदः
security: compression + secrets = CRIME-class risk । secret साथे विवेकः ॥६॥

Word-for-word

Gloss table

English sense
Be careful compressing responses that mix secrets with attacker-influenced bytes. Know historical TLS compression issues.

पदच्छेदः
object storage compress + CDNbr । precompress static assets ॥७॥

Word-for-word

Gloss table

English sense
Precompress static assets at build time; let the edge serve the right encoding without origin CPU.

Context / topic
Topic: static/edge. Links to CDN.

पदच्छेदः
columnar storage compress ratios । row store भिद्यते ॥८॥

Word-for-word

Gloss table

English sense
Warehouses and parquet-style files gain huge ratios from columnar compression; OLTP page compression is a different tradeoff.

पदच्छेदः
measure ratio CPU latency before/after । अन्धenable मिथ्याजयः ॥९॥

Word-for-word

Gloss table

English sense
Track compression ratio, CPU and p95 latency. A pretty ratio with worse p99 is not a win.

सिमान्तसञ्चयः encoding वहति सञ्चयधर्मः body स्मरेत् । संपीडनं उभयोः सेवकः ॥१०॥

Word-for-word

Gloss table

English sense
Edge caches must key or vary on Content-Encoding. App caches may store compressed blobs carefully.

Five limbs: choose layer, negotiate encodings, size thresholds, CPU levels and before/after metrics.
