Database configuration

Fields

max_open_files: i32

Max number of open files.

cache_sizes: HashMap<Option<u32>, usize>

Cache sizes (in MiB) for specific columns.

bloom_filters: HashMap<Option<u32>, u8>

Specific number of bloom filter bits, if any

compaction: CompactionProfile

Compaction profile

columns: Option<u32>

Set number of columns

wal: bool

Should we keep WAL enabled?

Methods

`impl DatabaseConfig`
[src]

`pub fn with_columns(columns: Option<u32>) -> Self`
[src]

Create new DatabaseConfig with default parameters and specified set of columns. Note that cache sizes must be explicitly set.

`pub fn set_cache(&mut self, col: Option<u32>, size: usize)`
[src]

Set the column cache size in MiB.
