* refactor: rename run_script api to run-script and test script manager
* fix: remove println
* refactor: error mod
* refactor: by CR comments
* feat: rebase develop and change timestamp/gmt_crated/gmt_modified type to timestamp
* refactor: use assert_eq instread of assert
* doc: fix comment in Script#execute function
LogicalTypeId to ConcreteDataType is only allowed in tests, since some
additional info is not stored in LogicalTypeId now. It is just an id, or
kind, not contains full type info.
* test: Fix merge tests
The merge tests still use Int64Vector for timestamp, which should
use TimestampVector instead.
* test: Test Debug format for Source::Reader
Mainly for improve code coverage
* wip: impl timestamp data type
* add timestamp vectors
* adapt to recent changes to vector module
* fix all unit test
* rebase develop

* feat: Implement MergeReader
* test: Add more tests
* feat: Use MergeReader to implement ChunkReader
Now the ChunkReaderImpl use MergeReader as default reader. Also add more tests to MergeReader.
* docs: Describe the merge algo in merge.rs
Ports the doc comments from kudu to merge.rs to describe the idea of the
merge algorithm we used.
* test: Fix unit tests
* chore: Address CR comments
Panics if number of columns in batch is not equal to `BatchBuilder`'s
* chore: Address CR comments

* fix: Fix MockChunkReader never stop
* feat: Impl cmp_element() for Vector
* chore: Add doc comments to MutableVector
* feat: Add create_mutable() to DataType
Add `create_mutable()` to create a MutableVector for each DataType.
Implement ListVectorBuilder and NullVectorBuilder for ListType and
NullType.
* feat: Add ValueRef
ValueRef is a reference to value, could be used to avoid some allocation
when getting data from Vector. To support ValueRef, also implement a
ListValueRef for ListValue, but comparision of ListValueRef still
requires some allocation, due to the complexity of ListValue and
ListVector.
Impl some From trait for ValueRef
* feat: Implement get_ref for Vector
* feat: Remove cmp_element from Vector
`cmp_element` could be replaced by `get_ref` and then compare
* feat: Implement push/extend for PrimitiveVectorBuilder
Implement push_value_ref() and extend_slice_of() for
PrimitiveVectorBuilder.
Also refactor the DataTypeBuilder trait for
primitive types to PrimitiveElement trait, adds necessary cast helper
methods to it.
- Cast a reference to Vector to reference arrow's primitive array
- Cast a ValueRef to primitive type
- Also make PrimitiveElement super trait of Primitive
* feat: Implement push/extend for all vector builders
Implement push_value_ref() and extend_slice_of() for remaining vector
builders. Add some helpful cast method to ValueRef and a method to
cast Value to ValueRef.
Change the behavior of PrimitiveElement::cast_xxx to panic when unable
to cast, since push_value_ref() and extend_slice_of() always panic
when given invalid input data type.
* feat: MutableVector returns error if data type unmatch
* test: Add tests for ValueRef
* feat: Add tests for Vector::get_ref
* feat: NullVector returns error if data type unmatch
* test: Add tests for vector builders
* fix: Fix compile error in python coprocessor
* refactor: Add lifetime param to IntoValueRef
The Primitive trait just use the `IntoValueRef<'static>` bound. Also
rename create_mutable to create_mutable_vector.
* chore: Address CR comments
* feat: Customize PartialOrd/Ord for Value/ValueRef
Panics if values/refs have different data type
* style: Fix clippy
* refactor: Use macro to generate body of ValueRef::as_xxx
* feat: implement alter table
* Currently we have no plans to support altering the primary keys (maybe never), so removed the related codes.
* make `alter` a trait function in table
* address other CR comments
* cleanup
* rebase develop
* resolve code review comments

Some PartialEq warnings have been work around using cfg_attr test
* feat: Implement Eq and PartialEq for PrimitiveType
* chore: Remove unnecessary allow
* chore: Remove usage of cfg_attr for PartialEq
* feat: save create table schema and respect user defined columns order when querying, close#179
* fix: address CR problems
* refactor: use with_context with ProjectedColumnNotFoundSnafu
* fix: ListVector::get returns Null if index is invalid
* feat: Implement eq for vector
* feat: Derive PartialEq for Batch
Simplify some test codes in schema mod
* refactor: Use macro to simplify vector equality check
* feat: Add projected schema
* feat: Use projected schema to read sst
* feat: Use vector of column to implement Batch
* feat: Use projected schema to convert batch to chunk
* feat: Add no_projection() to build ProjectedSchema
* feat: Memtable supports projection
The btree memtable use `is_needed()` to filter unneeded value columns,
then use `ProjectedSchema::batch_from_parts()` to construct
batch, so it don't need to known the layout of internal columns.
* test: Add tests for ProjectedSchema
* test: Add tests for ProjectedSchema
Also returns error if the `projected_columns` used to build the
`ProjectedSchema` is empty.
* test: Add test for memtable projection
* feat: Table pass projection to storage engine
* fix: Use timestamp column name as schema metadata
This fix the issue that the metadata refer to the wrong timestamp column
if datafusion reorder the fields of the arrow schema.
* fix: Fix projected schema not passed to memtable
* feat: Add tests for region projection
* chore: fix clippy
* test: Add test for unordered projection

* add some more test
Use `error!(e; xxx)` pattern so we could get backtrace in error log.
Also use BoxedError as error source of ExecuteQuery instead of String,
so we could carry backtrace and other info in it.
* feat: add `BorrowedValue` and DF Array access by index
This `BorrowedValue` can hold from datafusion arrow without copy.
`arrow_array_access` provides an index access to Arrow array and it holds the
result with our `BorrowedValue`. So we don't have to copy string/binary when
converting to `Value`.
* refactor: use borrowed types and iterator for recordbatch access
* fix: return Null with early check
* fix: i64 type error addressed by unit test
* refactor: give arrow_array_access a better name
* refactor: removed borrowed value and use value for now
* refactor: make iterator to return result of vec
* refactor: lift recordbatch iterator into common module
* fix: address clippy warnings
- Don't run github actions on draft pull requests
- Now the title checker won't be affected, seems due to it was triggered by pull_request_target, not pull_request event
This also fixes the dead code warning of `create_test_table()` as the
files under `datanode/tests` are considered as individual libs. Moves
them to src dir makes sharing codes much easier.
