Struct cfx_storage::KvdbSqliteStatements

pub struct KvdbSqliteStatements {
    pub stmts_main_table: KvdbSqliteStatementsPerTable,
    pub stmts_bytes_key_table: KvdbSqliteStatementsPerTable,
}

Fields

stmts_main_table: KvdbSqliteStatementsPerTable

stmts_bytes_key_table: KvdbSqliteStatementsPerTable

When numbered key is turned off, the bytes_key_table is the same as the main table.
