This work has shown that systems that store metadata on a single machine, or over a shared-disk abstraction, struggle to scale performance to deployments including billions of files. In contrast, leveraging a scalable, shared-nothing, distributed system for metadata storage can achieve much higher levels of scalability, without giving up high availability guarantees. However, for low-scale deployments – where metadata can fit in memory on a single machine – these systems that store metadata in a distributed database typically perform an order of magnitude worse than systems that store metadata in memory on a single machine. This has limited the impact of these distributed database approaches, since they are only currently applicable to file systems of extreme scale. + +FileScale is a three-tier architecture that incorporates a distributed database system as part of a comprehensive approach to metadata management in distributed file systems. In contrast to previous approaches, the architecture described in the paper performs comparably to the single-machine architecture at a small scale, while enabling linear scalability as the file system metadata increases. + +[Documentation](https://dslam-umd.github.io/docs/filescale) + +## License + +FileScale resources in this repository are released under the [Apache License

Cuckoo filters are probabilistic + * hash tables similar to Bloom filters but with several advantages. Like Bloom + * filters, a Cuckoo filter can determine if an object is contained within a set + * at a specified false positive rate with no false negatives. Like Bloom, a + * Cuckoo filter can determine if an element is probably inserted or definitely + * is not. In addition, and unlike standard Bloom filters, Cuckoo filters allow + * deletions and counting. They also use less space than a Bloom filter for + * similar performance. + * + *

+ * The false positive rate of the filter is the probability that + * {@linkplain #mightContain(Object)}} will erroneously return {@code true} for + * an object that was not added to the filter. Unlike Bloom filters, a Cuckoo + * filter will fail to insert when it reaches capacity. If an insert fails + * {@linkplain #put(Object)} will {@code return false} . + * + *

+ * Cuckoo filters allow deletion like counting Bloom filters using + * {@code #delete(Object)}. While counting Bloom filters invariably use more + * space to allow deletions, Cuckoo filters achieve this with no space or + * time cost. Like counting variations of Bloom filters, Cuckoo filters have a + * limit to the number of times you can insert duplicate items. This limit is + * 8-9 in the current design, depending on internal state. You should never + * exceed 7 if possible. Reaching this limit can cause further inserts to + * fail and degrades the performance of the filter. Occasional duplicates + * will not degrade the performance of the filter but will slightly reduce + * capacity. + * + *

+ * This Cuckoo filter implementation also allows counting the number of inserts + * for each item using {@code #approximateCount(Object)}. This is probabilistic + * like the rest of the filter and any error is always an increase. The count + * will never return less than the number of actual inserts, but may return + * more. The insert limit of 7 still stands when counting so this is only useful + * for small numbers. + * + *

+ * Once the filter reaches capacity ({@linkplain #put(Object)} returns false). + * It's best to either rebuild the existing filter or create a larger one. + * Deleting items in the current filter is also an option, but you should delete + * at least ~2% of the items in the filter before inserting again. + * + *

+ * Existing items can be deleted without affecting the false positive rate or + * causing false negatives. However, deleting items that were not + * previously added to the filter can cause false negatives. + * + *

+ * Hash collision attacks are theoretically possible against Cuckoo filters (as + * with any hash table based structure). If this is an issue for your + * application, use one of the cryptographically secure (but slower) hash + * functions. The default hash function, Murmer3 is not secure. Secure + * functions include SHA and SipHash. All hashes, including non-secure, are + * internally seeded and salted. Practical attacks against any of them are + * unlikely. + * + *
