[−][src]Struct rocks::table_properties::UserCollectedProperties

#[repr(C)]pub struct UserCollectedProperties { /* fields omitted */ }

Other than basic table properties, each table may also have the user collected properties.

The value of the user-collected properties are encoded as raw bytes -- users have to interprete these values by themselves.

Rust: wraps raw c pointer, and exposes as a {String => Vec<u8>} map

Common properties:

  • rocksdb.block.based.table.index.type
  • rocksdb.block.based.table.prefix.filtering
  • rocksdb.block.based.table.whole.key.filtering
  • rocksdb.deleted.keys
  • rocksdb.merge.operands
