Alexander Lapin updated IGNITE-16892:
-------------------------------------
Description:
1. Lock management logic will be introduced in IGNITE-17255
2. Lock storages will be introduced in IGNITE-15932
Given ticket is a sort of a bridge between 1 and 2 that will add several
methods similar to
{code:java}
/**
* Attempts to acquire a lock for the specified {@code key} in exclusive mode.
*
* @param key The key.
* @param txId Transaction id.
* @return The future that will be completed when a lock is successfully
acquired.
* @throws LockException When a lock can't be taken due to possible deadlock.

was:
1. Lock management logic will be introduced in IGNITE-17255
2. Lock storages will be introduced in IGNITE-15932
Given ticket is a sort of a bridge between 1 and 2 that will add several
methods similar to
{code:java}
// Index locks
public CompletableFuture<Void> writeLock(IgniteUuid lockId, ByteBuffer keyData,
UUID txId);
// Row store locks
public CompletableFuture<Void> writeLock(IgniteUuid lockId, RowId rowId, UUID
txId);

public CompletableFuture<Void> readLock(IgniteUuid lockId, RowId rowId, UUID
txId);
// Intent locks
public CompletableFuture<Void> readLock(IgniteUuid lockId, UUID txId);{code}
to TxManager with corresponding implementation.
