Aerospike Cache prepare content part missing

[dercoder]

The content will not be prepared like here:
https://github.com/phalcon/cphalcon/blob/master/phalcon/cache/backend/redis.zep#L226
https://github.com/phalcon/cphalcon/blob/master/phalcon/cache/backend/redis.zep#L173

The Aerospike client (C-extension) able to do it myself. Or I did not understand you. Could you please elaborate on that?

For example i want to use Igbinary or Base64 frontend to save this data in this format to Aerospike server.
Here
https://github.com/phalcon/incubator/blob/master/Library/Phalcon/Cache/Backend/Aerospike.php
the frontend cache convertation will be ignored.
$frontend->beforeStore(); and $frontend->afterRetrieve(); is missing in this code

Yes, I understand you. But what problems it causes?

Next example:

<?php 
$frontendCache = new Base64([
    'lifetime' => 1800
]);

$backendCache = new Aerospike($frontendCache, [
    'hosts'      => [
        ['addr' => '127.0.0.1', 'port' => 3000]
    ],
    'persistent' => true,
    'namespace'  => 'test',
    'prefix'     => 'cache_',
    'options'    => [
        \Aerospike::OPT_CONNECT_TIMEOUT => 1250,
        \Aerospike::OPT_WRITE_TIMEOUT   => 1500
    ]
]);

Data will be saved at Aerospike server as array and not as base64 string.
Other backend cache will convert it correct like Redis, Memcache, ...
So the Aerospike backend cache is not really compatible.

The reason why i convert the data is that Aerospike can not handle big arrays.
So i want to convert them to strings.

PHP Fatal error:  Uncaught exception 'Phalcon\Cache\Exception' with message 'Failed storing data in Aerospike: Cannot allocate as_string'

This is also very important to save data as bytes and not as strings.
