Member Data Documentation

bloom_filter

bool DBParams::bloom_filter = true

If true, build a LevelDB bloom filter to accelerate point lookups.

Definition at line 56 of file dbwrapper.h.

cache_bytes

uint64_t DBParams::cache_bytes

Configures various leveldb cache settings.

Definition at line 47 of file dbwrapper.h.

max_file_size

size_t DBParams::max_file_size = DBWRAPPER_MAX_FILE_SIZE

Maximum LevelDB SST file size.

Larger values reduce the frequency of compactions but increase their duration.

Definition at line 64 of file dbwrapper.h.

memory_only

bool DBParams::memory_only = false

If true, use leveldb's memory environment.

Definition at line 49 of file dbwrapper.h.

obfuscate

bool DBParams::obfuscate = false

If true, store data obfuscated via simple XOR.

If false, XOR with a zero'd byte array.

Definition at line 54 of file dbwrapper.h.

options

DBOptions DBParams::options {}

Passed-through options.

Definition at line 58 of file dbwrapper.h.

path

fs::path DBParams::path

Location in the filesystem where leveldb data will be stored.

Definition at line 45 of file dbwrapper.h.

testing_env

leveldb::Env* DBParams::testing_env = nullptr

If non-null, use this as the leveldb::Env instead of the default.

Caller retains ownership.

Definition at line 61 of file dbwrapper.h.

wipe_data

bool DBParams::wipe_data = false

If true, remove all existing data.

Definition at line 51 of file dbwrapper.h.
