Implementations§
Source§impl LockFreeMemTable
impl LockFreeMemTable
Sourcepub fn new() -> Self
👎Deprecated: Unused duplicate memtable; live memtables are lscs::ColumnarMemtable + durable_storage::MvccMemTable. Scheduled for removal (Task 2 consolidation).
pub fn new() -> Self
Unused duplicate memtable; live memtables are lscs::ColumnarMemtable + durable_storage::MvccMemTable. Scheduled for removal (Task 2 consolidation).
Create a new lock-free memtable
Sourcepub fn read(
&self,
key: &[u8],
snapshot_ts: u64,
txn_id: Option<u64>,
) -> Option<Vec<u8>>
👎Deprecated: Unused duplicate memtable; live memtables are lscs::ColumnarMemtable + durable_storage::MvccMemTable. Scheduled for removal (Task 2 consolidation).
pub fn read( &self, key: &[u8], snapshot_ts: u64, txn_id: Option<u64>, ) -> Option<Vec<u8>>
Unused duplicate memtable; live memtables are lscs::ColumnarMemtable + durable_storage::MvccMemTable. Scheduled for removal (Task 2 consolidation).
Read a value at snapshot timestamp
This is a lock-free read protected by hazard pointers. Returns a cloned value for safety across hazard pointer boundaries.
Sourcepub fn read_with<F, R>(
&self,
key: &[u8],
snapshot_ts: u64,
txn_id: Option<u64>,
f: F,
) -> Option<R>
👎Deprecated: Unused duplicate memtable; live memtables are lscs::ColumnarMemtable + durable_storage::MvccMemTable. Scheduled for removal (Task 2 consolidation).
pub fn read_with<F, R>( &self, key: &[u8], snapshot_ts: u64, txn_id: Option<u64>, f: F, ) -> Option<R>
Unused duplicate memtable; live memtables are lscs::ColumnarMemtable + durable_storage::MvccMemTable. Scheduled for removal (Task 2 consolidation).
Read a value at snapshot timestamp with zero-copy callback
This is an optimized read path that avoids cloning for inline values. The callback receives a reference to the value, avoiding allocation.
§Arguments
key- The key to readsnapshot_ts- Snapshot timestamp for visibilitytxn_id- Current transaction ID (to see own uncommitted writes)f- Callback that receives the value reference
§Returns
The result of the callback, or None if key not found
Sourcepub fn write(
&self,
key: Vec<u8>,
value: Option<Vec<u8>>,
txn_id: u64,
) -> Result<()>
👎Deprecated: Unused duplicate memtable; live memtables are lscs::ColumnarMemtable + durable_storage::MvccMemTable. Scheduled for removal (Task 2 consolidation).
pub fn write( &self, key: Vec<u8>, value: Option<Vec<u8>>, txn_id: u64, ) -> Result<()>
Unused duplicate memtable; live memtables are lscs::ColumnarMemtable + durable_storage::MvccMemTable. Scheduled for removal (Task 2 consolidation).
Write a value (creates uncommitted version)
Sourcepub fn commit(&self, txn_id: u64, commit_ts: u64, keys: &[Vec<u8>])
👎Deprecated: Unused duplicate memtable; live memtables are lscs::ColumnarMemtable + durable_storage::MvccMemTable. Scheduled for removal (Task 2 consolidation).
pub fn commit(&self, txn_id: u64, commit_ts: u64, keys: &[Vec<u8>])
Unused duplicate memtable; live memtables are lscs::ColumnarMemtable + durable_storage::MvccMemTable. Scheduled for removal (Task 2 consolidation).
Commit a transaction’s writes
Sourcepub fn has_write_conflict(&self, key: &[u8], txn_id: u64) -> bool
👎Deprecated: Unused duplicate memtable; live memtables are lscs::ColumnarMemtable + durable_storage::MvccMemTable. Scheduled for removal (Task 2 consolidation).
pub fn has_write_conflict(&self, key: &[u8], txn_id: u64) -> bool
Unused duplicate memtable; live memtables are lscs::ColumnarMemtable + durable_storage::MvccMemTable. Scheduled for removal (Task 2 consolidation).
Check for write conflict
Sourcepub fn size_bytes(&self) -> usize
👎Deprecated: Unused duplicate memtable; live memtables are lscs::ColumnarMemtable + durable_storage::MvccMemTable. Scheduled for removal (Task 2 consolidation).
pub fn size_bytes(&self) -> usize
Unused duplicate memtable; live memtables are lscs::ColumnarMemtable + durable_storage::MvccMemTable. Scheduled for removal (Task 2 consolidation).
