/**
- * Main object stash type. This should be a fast storage system for storing
- * lightweight data like hit counters and user activity. Sites with multiple
- * data-centers should have this use a store that replicates all writes. The
- * store should have enough consistency for CAS operations to be usable.
- * Reads outside of those needed for merge() may be eventually consistent.
+ * The object store type of the main stash.
+ *
+ * This store should be a very fast storage system optimized for holding lightweight data
+ * like incrementable hit counters and current user activity. The store should replicate the
+ * dataset among all data-centers. Any add(), merge(), lock(), and unlock() operations should
+ * maintain "best effort" linearizability; as long as connectivity is strong, latency is low,
+ * and there is no eviction pressure prompted by low free space, those operations should be
+ * linearizable. In terms of PACELC (https://en.wikipedia.org/wiki/PACELC_theorem), the store
+ * should act as a PA/EL distributed system for these operations. One optimization for these
+ * operations is to route them to a "primary" data-center (e.g. one that serves HTTP POST) for
+ * synchronous execution and then replicate to the others asynchronously. This means that at
+ * least calls to these operations during HTTP POST requests would quickly return.
+ *
+ * All other operations, such as get(), set(), delete(), changeTTL(), incr(), and decr(),
+ * should be synchronous in the local data-center, replicating asynchronously to the others.
+ * This behavior can be overriden by the use of the WRITE_SYNC and READ_LATEST flags.
+ *
+ * The store should *preferably* have eventual consistency to handle network partitions.
+ *
+ * Modules that rely on the stash should be prepared for:
+ * - add(), merge(), lock(), and unlock() to be slower than other write operations,
+ * at least in "secondary" data-centers (e.g. one that only serves HTTP GET/HEAD)
+ * - Other write operations to have race conditions accross data-centers
+ * - Read operations to have race conditions accross data-centers
+ * - Consistency to be either eventual (with Last-Write-Wins) or just "best effort"
+ *
+ * In general, this means avoiding updates during idempotent HTTP requests (GET/HEAD) and
+ * avoiding assumptions of true linearizability (e.g. accepting anomalies). Modules that need
+ * these kind of guarantees should use other storage mediums.
*
* The options are:
* - db: Store cache objects in the DB
* temporary storage. Preprocessor_DOM generally uses less memory;
* the speed of the two is roughly the same.
*
- * If this parameter is not given, it uses Preprocessor_DOM if the
- * DOM module is available, otherwise it uses Preprocessor_Hash.
+ * If this parameter is not given, it uses Preprocessor_Hash.

* release.
