Summary: This diff removes: `SingleNodeRecoveryTransactions`, `TypemapPack` It also removes virtual and/or pimpl from: `SingleNodeCounters`, `StorageGcSingleNode`, `SingleNodeConcurrentIdMapper`, accessors (revert D1510), transaction engine, `GraphDbAccessor`, `GraphDb` Reviewers: msantl, teon.banek Reviewed By: msantl, teon.banek Subscribers: pullbot Differential Revision: https://phabricator.memgraph.io/D1639	2018-10-09 11:48:30 +02:00
Matej Ferencevic	96ece11cdd	Move distributed transaction engine logic ... Summary: This change introduces a pure virtual initial implementation of the transaction engine which is then implemented in two versions: single node and distributed. The interface classes now have the following hierarchy: ``` Engine (pure interface) | +----+---------- EngineDistributed (common logic) | | EngineSingleNode +-------+--------+ | | EngineMaster EngineWorker ``` In addition to this layout the `EngineMaster` uses `EngineSingleNode` as its underlying storage engine and only changes the necessary functions to make them work with the `EngineWorker`. After this change I recommend that you delete the following leftover files: ``` rm src/distributed/transactional_cache_cleaner_rpc_messages.* rm src/transactions/common.* rm src/transactions/engine_rpc_messages.* ``` Reviewers: teon.banek, msantl, buda Reviewed By: teon.banek Subscribers: pullbot Differential Revision: https://phabricator.memgraph.io/D1589	2018-09-07 11:43:57 +02:00
