Snappy compression is not working

[ghost]

hi,

I'm using both of your extensions for Magento Session cache and Backend cache, and I'm trying to use snappy compression, which is working fine for the Session cache, but when I configure the Backend Session I'm getting the error like the extension wasn't installed: PHP Fatal error: Call to undefined function snappy_compress() in /data/web/public/lib/Cm/Cache/Backend/Redis.php on line 866

Here's my configuration file:

        <cache> 
            <backend>Cm_Cache_Backend_Redis</backend>
            <backend_options>
                <server>redismaster</server>
                <port>6379</port>
                <persistent />
                <database>0</database>
                <password />
                <force_standalone>0</force_standalone>
                <connect_retries>1</connect_retries>
                <read_timeout>10</read_timeout>
                <automatic_cleaning_factor>0</automatic_cleaning_factor>
                <compress_data>1</compress_data>
                <compress_tags>1</compress_tags>
                <compress_threshold>20480</compress_threshold>
                <compression_lib>snappy</compression_lib>
            </backend_options>
        </cache>

You need the php extension installed

Hello @Xon I’m sorry if I wasn’t so clear. The extension is installed and is working fine with the Cm_RedisSession module. The problem only happens with the backend cache module.

Issue solved after proper PHP extension configuration.

@maaxxicarvalho I'm having the same issue. But I'm not sure how to solve it. What extention did you configure?

Hi @GuiltyNL

Actually, the only thing I did was double check the server to see if the extension installation was ok.
Then I had to flush the cache (including Redis) completely.

Below you can find my current configuration (local.xml) which is working fine.

    <global>
        <redis_session>
            <host>redismaster</host>

            <password/>
            <timeout>2.5</timeout>
            <persistent></persistent>
            <db>2</db>
            <compression_threshold>2048</compression_threshold>
