In LSM, data is periodically dropped to different SST files through Compaction operations. During data reading, each SST file provides a BloomFilter to check whether the key exists in the file. It is known that when the BloomFilter returns false, it is 100% guaranteed that the current key is not in the SST file. However, when the BloomFilter returns true, it indicates that the key may or may not exist in the SST file. In this case, the key is false positive. The query performance of LSM-based KV storage database depends largely on the false positive rate. The goal is to design an algorithm that can effectively reduce the false positive rate of BloomFilter. Expectations are reduced by more than 10%, the higher the better.

"Billions of users have now data written with Facebook Zstandard (ZSTD) or Apple LZFSE compressors, which use tANS (tabled asymmetric numeral systems) entropy coder – building finite automaton optimized for a given probability distribution, which transforms symbol sequence into bit sequence.
Details of this automaton are determined by symbol spread (combination): assignment of one symbol to each state. There is exponential number of such
possibilities, getting various performances as mean numbers of used bits/symbol – there is basic practical problem of quickly finding nearly optimal symbol spread."

For database management systems, a large amount of work has been done to explore parallel processing of database operations. Special database machines have been designed to obtain increased system performance through both inter-query and intra-query parallelism. However, most of the existing relational database query optimizers only consider plans in which the execution order is modeled by a linear processing tree. An M-way join query is visualized as a sequence of 2-way joins of the form. This strategy seems adequate in uniprocessor systems.In a multiprocessor environment, however, the number of feasible join plans increases dramatically with new dimensions introduced by parallelism and parallel processing tends to give better overall system performance. In this topic, we expect that multi-way join should perform significantly better (at less 20%) than pair-wise joining of tables for a given example database.
