Summary: FullFilterBitsBuilder::CalculateSpace use CACHE_LINE_SIZE which is 64@X86 but 128@ARM64 when it run bloom_test.FullVaryingLengths it failed on ARM64 server, the assert can be fixed by change 128->CACHE_LINE_SIZE*2 as merged ASSERT_LE(FilterSize(), (size_t)((length * 10 / 8) + CACHE_LINE_SIZE * 2 + 5)) << length; run bloom_test before fix: /root/rocksdb-master/util/bloom_test.cc:281: Failure Expected: (FilterSize()) <= ((size_t)((length * 10 / 8) + 128 + 5)), actual: 389 vs 383 200 [ FAILED ] FullBloomTest.FullVaryingLengths (32 ms) [----------] 4 tests from FullBloomTest (32 ms total) [----------] Global test environment tear-down [==========] 7 tests from 2 test cases ran.

RocksDB: A Persistent Key-Value Store for Flash and RAM Storage
RocksDB is developed and maintained by Facebook Database Engineering Team. It is built on earlier work on LevelDB by Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)
This code is a library that forms the core building block for a fast key value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it specially suitable for storing multiple terabytes of data in a single database.
