Struct re_data_store::DataStoreConfig

pub struct DataStoreConfig {
    pub indexed_bucket_num_rows: u64,
    pub store_insert_ids: bool,
}

Fields

indexed_bucket_num_rows: u64

The maximum number of rows in an indexed bucket before triggering a split. Does not apply to static data.

⚠ When configuring this threshold, do keep in mind that indexed tables are always scoped to a specific timeline and a specific entity.

This effectively puts an upper bound on the number of rows that need to be sorted when an indexed bucket gets out of order (e.g. because of new insertions or a GC pass). This is a tradeoff: less rows means faster sorts at the cost of more metadata overhead. In particular:

• Query performance scales inversely logarithmically to this number (i.e. it gets better the higher this number gets).
• GC performance scales quadratically with this number (i.e. it gets better the lower this number gets).

See Self::DEFAULT for defaults.

store_insert_ids: bool

If enabled, will store the ID of the write request alongside the inserted data.

This can make inspecting the data within the store much easier, at the cost of an extra u64 value stored per row.

Enabled by default in debug builds.

Implementations

pub const DEFAULT: Self = _

Trait Implementations

impl Clone for DataStoreConfig

fn clone(&self) -> DataStoreConfig

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DataStoreConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for DataStoreConfig

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for DataStoreConfig

fn eq(&self, other: &DataStoreConfig) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
