Fetch values of keys from cache
Syntax
Description
Examples
Get Values for Keys from 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.
put(c,'keyOne',10,'keyTwo',20,'keyThree',30,'keyFour',[400 500],'keyFive',magic(5))
Get all the keys and associated values and display them as a MATLAB® table.
k = keys(c) v = get(c,{'keyOne','keyTwo','keyThree','keyFour','keyFive'}) tt = table(keys(c), get(c,keys(c))','VariableNames',{'Keys','Values'})
k = 5×1 cell array {'keyFive' } {'keyFour' } {'keyOne' } {'keyThree'} {'keyTwo' } v = 1×5 cell array {[10]} {[20]} {[30]} {1×2 double} {5×5 double} tt = 5×2 table Keys Values __________ ____________ 'keyFive' [5×5 double] 'keyFour' [1×2 double] 'keyOne' [ 10] 'keyThree' [ 30] 'keyTwo' [ 20]
Input Arguments
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 type mps.cache.RedisCache
or
mps.cache.MATFileCache
.
Example: c
keys
— Keys
cell array of character vectors
A cell array of keys whose values you want to retrieve from cache.
Example: {'keyOne','keyTwo','keyThree','keyFour','keyFive'}
Output Arguments
values
— Values
cell array
A list of values associated with keys, returned as a cell array.
