Struct PartitionedTable 

pub struct PartitionedTable<V> { /* private fields */ }

Generic partitioned table that stores values in sharded segments.

This type provides the core storage infrastructure without knowing anything about specific value types. It handles the mechanics of:

• Sharding writes across multiple partitions
• Segmenting large values to control write amplification
• Optional meta table for O(1) head segment discovery

The V parameter represents the value handler type that knows how to encode/decode and manipulate specific value types.

Implementations

impl<V> PartitionedTable<V>

pub fn new(name: &'static str, config: PartitionConfig) -> Self

Creates a new partitioned table with the given configuration.

Arguments

• name - Table name for database storage
• config - Partitioning configuration

Returns

New partitioned table instance

pub fn ensure_table_exists(&self, db: &Database) -> Result<()>

Ensures required tables exist in the database.

This method creates the segment table and optionally the meta table if they don’t already exist.

Arguments

• db - The database instance

Returns

Ok on success, error on failure

pub fn name(&self) -> &'static str

Returns the table name.

pub fn config(&self) -> &PartitionConfig

Returns the configuration.

pub fn select_shard(&self, key: &[u8], element_id: u64) -> Result<u16>

Selects the appropriate shard for a given base key and element.
