When a transaction is in read-confirmed state it must ignore all
prepared changes, and if it actually ignores something - it must
fall to read-view state.

By a mistake the check relied not on actual skipping of a prepared
statement, but on the fact that there is a deleting statement. That
leads to excess conflicts for transactions with read-committed
isolation level.

Fix it by raising a conflict only if a deleting statement is skipped.

Closes #8122
Needed for #7202

Tarantool is an in-memory computing platform consisting of a database and an application server.

It is distributed under BSD 2-Clause terms.

Key features of the application server:

Key features of the database:

  • MessagePack data format and MessagePack based client-server protocol.
  • Two data engines: 100% in-memory with complete WAL-based persistence and an own implementation of LSM-tree, to use with large data sets.
  • Multiple index types: HASH, TREE, RTREE, BITSET.
  • Document oriented JSON path indexes.
  • Asynchronous master-master replication.
  • Synchronous quorum-based replication.
  • RAFT-based automatic leader election for the single-leader configuration.
  • Authentication and access control.
  • ANSI SQL, including views, joins, referential and check constraints.
  • Connectors for many programming languages.
  • The database is a C extension of the application server and can be turned off.

Supported platforms are Linux (x86_64, aarch64), Mac OS X (x86_64, M1), FreeBSD (x86_64).

Tarantool is ideal for data-enriched components of scalable Web architecture: queue servers, caches, stateful Web applications.
