✨💨 Orama Cache

This plugin provides a cache system for Orama. The cache system is based on async-cache-dedupe.

🚀 Getting Started

📦 Installation

# You can install Orama using `npm`, `yarn`, `pnpm`:
npm install orama-cache

📝 Usage

Example using the default storage (memory)

import { create, insert } from "@orama/orama"
import { createOramaCache } from "orama-cache"

(async() => {
  const db = create({ schema: { name: "string" } })

  await insert(db, { name: "foo" })
  await insert(db, { name: "bar" })

  const cache = await createOramaCache(db) // Create the cache.

  const results = await cache.search({ term: "foo" }) // This method will return the results and cache them.

  // ...

  const cachedResults = await cache.search({ term: "foo" }) // Returns the cached results.
})()

📖 Documentation

You can use the same APIs as async-cache-dedupe.

Example using Redis as storage

const oramaCache = createOramaCache({
  storage: {
    type: 'redis',
    options: {
      client: new Redis(),
      invalidation: {
        invalidates: true,
        referencesTTL: 60 // seconds
      }
    }
  }
})

📈 Benchmarks

Some searches can be ~2K faster using a cache system.

{
  elapsedTime: '81ms',
  fetchRes: {
    elapsed: 81312667n,
    hits: [
      [Object], [Object],
      [Object], [Object],
      [Object], [Object],
      [Object], [Object],
      [Object], [Object]
    ],
    count: 100000
  }
}
// Cached result, same searched `term`
{
  elapsedTimeCached: '40μs',
  fetchCached: {
    elapsed: 81312667n,
    hits: [
      [Object], [Object],
      [Object], [Object],
      [Object], [Object],
      [Object], [Object],
      [Object], [Object]
    ],
    count: 100000
  }
}

✅ Results

The orama-cache plugin provides a set of benchmarks to compare the performance of the cache system with the default search.

npm run benchmark

⚠️ Testing

To run the tests you should run the following commands:

npm run redis

That command shall start a new Redis istance using Docker. Then run the tests.

npm run test
