It’s a good idea not to put the caching logic directly into your repository, as that violates the Single Responsibility Principle (SRP) and Separation of Concerns. SRP essentially states that your classes should only have one reason to change. If you conflate the concerns of data access and caching policy in the same class, then … Read more
Spark 2.x You can use Catalog.clearCache: from pyspark.sql import SparkSession spark = SparkSession.builder.getOrCreate … spark.catalog.clearCache() Spark 1.x You can use SQLContext.clearCache method which Removes all cached tables from the in-memory cache. from pyspark.sql import SQLContext from pyspark import SparkContext sqlContext = SQLContext.getOrCreate(SparkContext.getOrCreate()) … sqlContext.clearCache()
A more efficient (and easier) method is to set the test environment’s cache to use NullStore: # config/environments/test.rb: config.cache_store = :null_store The NullStore ensures that nothing will ever be cached. For instance in the code below, it will always fall through to the block and return the current time: Rails.cache.fetch(‘time’) { Time.now } Also see … Read more

That’s why gmapcatcher has it crossed off their list. See http://code.google.com/p/gmapcatcher/issues/detail?id=210. At the gmapcatcher URL above, you will also find a shell … Read more
See this answer – Set expiration policy for cache using Google’s Volley This means Volley decides whether to cache response or not based only on headers “Cache-Control” and then “Expires”, “maxAge”. What you could do is change this method com.android.volley.toolbox.HttpHeaderParser.parseCacheHeaders(NetworkResponse response) and ignore these headers, set entry.softTtl and entry.ttl fields to whatever value works for … Read more
Caching just means keeping a copy of the data that you need so that you don’t have to load it from some slower source.
