What is the best caching strategy that ensures that data is always fresh and does not fail with empty nodes?

Write-through
Write-through ensures that data is always fresh, but can fail with empty nodes and can populate the cache with superfluous data.

What is the best caching strategy?

5 Different Types of Server Caching Strategies

1. Cache-Aside. In this caching strategy, the cache is logically placed at the side and the application directly communicates with the cache and the database to know if the requested information is present or not.
2. Write-Through Cache.
3. Read-Through Cache.
4. Write-Back.
5. Write-Around.

What are the two main strategies of caching?

What are the top caching strategies?

• Cache Aside. In this strategy, the cache is sitting aside the database.
• Read Through. Unlike cache aside, the cache sits in between the application and the database.
• Write Through. Similar to read through, the cache sits in between.
• Write Back (a.k.a Write Behind)
• Write Around.

How do you improve performance cache?

The performance of cache memory is frequently measured in terms of a quantity called Hit ratio. We can improve Cache performance using higher cache block size, higher associativity, reduce miss rate, reduce miss penalty, and reduce the time to hit in the cache.

What caching solutions are out there?

AWS Caching Solutions

• Amazon ElastiCache. Amazon ElastiCache is a web service that makes it easy to deploy, operate, and scale an in-memory data store and cache in the cloud.
• Amazon DynamoDB Accelerator (DAX)
• Amazon CloudFront.
• AWS Greengrass.
• Amazon Route 53.

How do I increase my cache hits?

To increase your cache hit ratio, you can configure your origin to add a Cache-Control max-age directive to your objects, and specify the longest practical value for max-age .

What is cache coherence in computer architecture?

In computer architecture, cache coherence is the uniformity of shared resource data that ends up stored in multiple local caches. When clients in a system maintain caches of a common memory resource, problems may arise with incoherent data, which is particularly the case with CPUs in a multiprocessing system.

How do you reduce cache miss penalty?

1. Reduce Conflict Misses via Higher Associativity. Reducing Conflict Misses via Victim Cache.
2. Reducing Conflict Misses via Pseudo-Associativity. Reducing Misses by HW Prefetching Instr, Data.
3. Reducing Misses by SW Prefetching Data. Reducing Capacity/Conf. Misses by Compiler Optimizations.

What affects cache performance?

Cache performance depends on cache hits and cache misses, which are the factors that create constraints to system performance. Cache hits are the number of accesses to the cache that actually find that data in the cache, and cache misses are those accesses that don’t find the block in the cache.
