Query: Fast Succinct Retrieval and Approximate Membership using Ribbon   A retrieval data structure for a static function $f:S\rightarrow \{0,1\}^r$
supports queries that return $f(x)$ for any $x \in S$. Retrieval data
structures can be used to implement a static approximate membership query data
structure (AMQ), i.e., a Bloom filter alternative, with false positive rate
$2^{-r}$. The information-theoretic lower bound for both tasks is $r|S|$ bits.
While succinct theoretical constructions using $(1+o(1))r|S|$ bits were known,
these could not achieve very small overheads in practice because they have an
unfavorable space--time tradeoff hidden in the asymptotic costs or because
small overheads would only be reached for physically impossible input sizes.
With bumped ribbon retrieval (BuRR), we present the first practical succinct
retrieval data structure. In an extensive experimental evaluation BuRR achieves
space overheads well below 1\,\% while being faster than most previously used
retrieval data structures (typically with space overheads at least an order of
magnitude larger) and faster than classical Bloom filters (with space overhead
$\geq 44\,\%$). This efficiency, including favorable constants, stems from a
combination of simplicity, word parallelism, and high locality. We additionally
describe homogeneous ribbon filter AMQs, which are even simpler and faster at
the price of slightly larger space overhead.
