Because of the lexicographical sharding, the primary labels themselves are
acting as indexes. If a primary label is specified in a MATCH query we can
safely narrow the range of shards we have to scan through based on that label.
This PR introduces the necessary changes in order to achieve that.
This PR adds support for generating randomized workloads that will be executed
against a simulated cluster, as well as against a correctness model. Initially
this just generates ScanAll and CreateVertex requests, and anything that it
creates, it also inserts into a `std::set`, and when we do a ScanAll, it asserts
that we get the same number of requests back. This will become much more
sophisticated over time, but it's already hitting pay-dirt.
ScanVerticesrequest was not able to utilize filtering capabilities
before. With these modification it is now able to filter the scanned
vertices based on the filter_expressions field in the
ScanVerticesRequest message type.
The communication between the ShardRequestManager and the RsmClient
used to be direct. In this PR this changes into a future-based
communication type. The RsmClient stores state about the currently
processed future (either read or write request) and exposes blocking
and non-blocking functionality to obtain the filled future. The
ShardRequestManager -for now- will send of the set of requests present
in the ExecutionState and block on each of them until the requests are
completed or the set of paginated responses(caused by, for example the
batch-limit in ScanAll) are ready for the next round.
* Use query-v2 in the main executable
* Set up machine manager in memgraph
* Add `ShardRequestManager` to `Interpreter`
* Make vertex creation work
* Make scan all work
* Add edge type map in shard request manager
* Send schema over request
* Empty out DbAccessor
* Store shard mapping at creation
* Remove failing CI steps

- Enable `mg-expr` in mg-storage-v3
- Adapt id_mapper
- Change conversion function from PropertyValue to TypedValue
- Remove memgraph functions
- Enable expression tests on for storage
Create shard-side handlers for basic messages
Implement the handlers for CreateVertices, CreateEdges and ScanAll. Use
or modify the defined messages to interact with individual Shards and
test their behavior. Shard is currently being owned by ShardRsm
instances. The two top level dispatching functions Read() and Apply()
are responsible for read- and write operations respectively. Currently
there are a handful of messages that are defined but not utilized, these
will be used in the near future, as well as a couple of handler
functions with empty implementations.
* Remove logic that was necessary for optimal multi-threaded performance, such
as accumulating deleted object in local containers and appending them to a
global one, handling overlapping locking.
* Remove background GC thread.
* Remove mutexes, locks and atomics throughout storage.
- Integrate schema and keystore on vertex creation
- Add GC test for storage v3
- Add tests for accessors
- Fix all tests related to this except for query v2
- Fix labels not returning primary label
* Create LocalTransport Io provider for sending messages to components on the same machine
* Move src/io/simulation/message_conversion.hpp to src/io/message_conversion.hpp for use in other Io providers
* Move schema to storage v3
* Remove schema from v2
* Move schema to query v2
* Remove schema from query v1
* Make glue v2
* Move schema related tests to newer versions of query and storage
* Fix typo in CMake
* Fix interpreter test
* Fix clang tidy errors
* Change temp dir name
* Fix aggregation functions on `null` and group-by inputs (#448)
* Upgrade Antrl to 4.10.1 and remove antlr_lock (#441)
* Update clang-tidy job (#476)
* Add parser stress test (#463)
