During EntityCompanionProvider instantiation:

``typescript
import Redis from 'ioredis';

const genericRedisCacherContext = {
redisClient: new Redis(new URL(process.env['REDIS_URL']!).toString()),
makeKeyFn(...parts: string[]): string {
const delimiter = ':';
const escapedParts = parts.map((part) =>
part.replace('\\', '\\\\').replace(delimiter, \\${delimiter})
);
return escapedParts.join(delimiter);
},
cacheKeyPrefix: 'ent-',
ttlSecondsPositive: 86400, // 1 day
ttlSecondsNegative: 600, // 10 minutes
};

export const createDefaultEntityCompanionProvider = (
metricsAdapter: IEntityMetricsAdapter = new NoOpEntityMetricsAdapter()
): EntityCompanionProvider => {
return new EntityCompanionProvider(
metricsAdapter,
{
...
},
{
['redis']: {
cacheAdapterProvider: new RedisCacheAdapterProvider(genericRedisCacheContext),
},
}
