ScyllaDB Adapter (scylla)#

Factory:

Cache::scylla(string $namespace = 'default', ?object $session = null, string $keyspace = 'cachelayer', string $table = 'cachelayer_entries', int $bucketCount = 128)

Requirements:

  • injected ScyllaDB/Cassandra session object exposing execute(), or

  • ext-cassandra (for default session creation path)

Highlights:

  • keyspace/table-backed cache entries with bounded partition buckets

  • bucket-grouped IN reads and bounded unlogged write batches

  • schema bootstrap with CREATE TABLE IF NOT EXISTS

  • native Scylla TTL on data rows, plus the absolute expiration timestamp used for read-time validation

  • binary blob payload storage without Base64 expansion

Supported injected session methods:

  • execute

  • prepare (optional, used when available)

Example#

use Infocyph\CacheLayer\Cache\Cache;

$cache = Cache::scylla(
    namespace: 'edge',
    keyspace: 'cachelayer',
    table: 'cachelayer_entries',
);

$cache->set('homepage.blocks', $blocks, 45);
