Get the Number of Bytes of Storage Used by a Value in the Cache
Start a persistence service that uses Redis™ as the persistence provider. The service requires a connection name and an open port. Once the service is running, you can connect to the service using the connection name and create a cache.
ctrl = mps.cache.control('myRedisConnection','Redis','Port',4519); start(ctrl) c = mps.cache.connect('myCache','Connection','myRedisConnection');
Add keys and values to the cache and then get the number of bytes of storage used by a value stored at each key in the cache. Represent the keys and the bytes used by each value of key as a MATLAB®table.
put (c,'keyOne',10,'keyTwo',20,'keyThree',30,'keyFour',[400 500],'keyFive',magic(5)) b = bytes(c,{'keyOne','keyTwo','keyThree','keyFour','keyFive'}) tt = table(keys(c), bytes(c,keys(c))','VariableNames',{'Keys','Bytes'})
c—Data cache persistence provider specific data cache object
A data cache represented by a persistence provider specific data cache object.
Currently, Redis and MATLAB are the only supported persistence providers. Therefore, the cache objects will be of typemps.cache.RedisCacheormps.cache.MATFileCache.
Example:c
keys—Keys cell array of character vectors
A list of all the keys, specified as a cell array of character vectors.
