* feat: Add `open_table()` method to `TableEngine`
* feat: Implements MitoEngine::open_table()
For simplicity, this implementation just use the table name as region
name, and using that name to open a region for that table. It also
introduce a mutex to avoid opening the same table simultaneously.
* refactor: Shorten generic param name
Use `S` instead of `Store` for `MitoEngine`.
* test: Mock storage engine for table engine test
Add a `MockEngine` to mock the storage engine, so that testing the mito
table engine can sometimes use the mocked storage.
* test: Add open table test
Also remove `storage::gen_region_name` method, and always use table name
as default region name, so the table engine can open the table created
by `create_table()`.
* chore: Add open table log
* feat: Implements RegionWriter::replay()
Refactors `preprocess_write()`, wraps time ranges calculation and
memtable creation to `prepare_memtables()` so these logic can be reused
by `WriterInner::replay()`. Then implements `WriterInner::replay()`
which reads write batch from wal and inserts it into memtables.
* feat: Use sequence in request as committed sequence
Also checks that sequence should increase monotonically and returns
error if found sequence decreases
* chore: Remove OpenOptions param from RegionWriter::replay
* test: Add region reopen tests
refactor(storage): Rename read_write test mod to basic
refactor(storage): Move common region test logic to TesterBase
Let read/write Tester and flush Tester share the same TesterBase struct,
which implements common operations like put/full_scan.
* feat: Constructs RegionImpl in open()
Constructs RegionImpl after replay in `RegionImpl::open()`
* feat: Adds RegionImpl::create()
Adds `RegionImpl::create()` method to persist region metadata to
manifest, then create the RegionImpl instance, so the storage engine
just invoke `RegionImpl::create()` instead of `RegionImpl::new()` to
create the region instance, and don't need to update manifest after
creating region instance anymore. Now `RegionImpl::new()` need to takes
version instead of metadata as input.
This change is also a necessary part to pass the region open test, since
to open a region, need to persist something to manifest first.
* feat: Pass region open test
Use LocalFileLogStore for region test since NoopLogStore won't persist
data to the file system.
Create dir in `LocalFileLogStore::open` if it is not exist, so we don't
need to create the dir before using the logstore.
To pass the test, we always recover from flushed_sequence and use
`req_sequence + 1` as last sequence.
* test: Test reopen region multiple times
* chore: Address CR comments
Add more info to replay log and add an assert to check committed
sequence after reopen.
* refactor: Add cfg(test) to Version::new()
Remove `VersionControl::new()`, and add `#[cfg(test)]` to
`Version::new()` as it is only used by tests.
* feat: impl recovering version from manifest for region
* refactor: rename try_apply_edit to replay_edit
* fix: remove println
* fix: address CR problems
* feat: remove Metadata in manifest trait and update region manifest state after recovering
* refactor: Move fields in SharedData to EngineInner
Since `SharedData` isn't shared now, we move all its fields to
EngineInner, and remove the `SharedData` struct, also remove the
unused config field.
* feat: Store RegionSlot in engine's region map
A `RegionSlot` has three possible state:
- Opening
- Creating
- Ready (Holds the `RegionImpl`)
Also use the `RegionSlot` as a placeholder in the region map to indicate
the region is opening/creating, so another open/create request will
fail immediately. The `SlotGuard` is used to clean the slot if we failed
to create/open the region.
* feat: Add a blank method `RegionImpl::open`
* feat: Remove MetadataId from Manifest
Now metadata id of manifest is unused, also unnecessary as we have
manifest dir to build the manifest, but constructing the manifest
still needs a passing region id as argument, which is unavailable
during opening region. So we remove the metadata id from manifest so
`region_store_config()` don't need region id as input anymore
* feat: Remove region id from logstore::Namespace and Wal
This is necessary for implementing open, since we don't have region
id this time, but we need to build Wal and its logstore namespace. Now
this is ok as id is not actually used by logstore.
* feat: Setup `open_region` code skeleton
* fix: Fix write stall blocks flush applying version
refactor: Use store config to help constructing Region
chore: Address CR comments
* feat: adds manifest protocol supporting and refactor region metadata protocol
feat: ignore sqlparser log
refactor: PREV_VERSION_KEY constant
refactor: minor change for checking readable/writable
fix: address CR problems
refactor: use binary literal
