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.
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.
* refactor: Merge RowKeyMetadata into ColumnsMetadata
Now RowKeyMetadata and ColumnsMetadata are almost always being used together, no need
to separate them into two structs. Now they are combined into the single
ColumnsMetadata struct.
chore: Make some fields of metadata private
feat: Replace schema in RegionMetadata by RegionSchema
The internal schema of a region should have the knownledge about all
internal columns that are reserved and used by the storage engine, such as
sequence, value type. So we introduce the `RegionSchema`, and it would
holds a `SchemaRef` that only contains the columns that user could see.
feat: Value derives Serialize and supports converting into json value
feat: Add version to schema
The schema version has an initial value 0 and would bump each time the
schema being altered.
feat: Adds internal columns to region metadata
Introduce the concept of reserved columns and internal columns.
Reserved columns are columns that their names, ids are reserved by the storage
engine, and could not be used by the user. Reserved columns usually have
special usage. Reserved columns expect the version columns are also
called internal columns (though the version could also be thought as a
special kind of internal column), are not visible to user, such as our
internal sequence, value_type columns.
The RegionMetadataBuilder always push internal columns used by the
engine to the columns in metadata. Internal columns are all stored
behind all user columns in the columns vector.
To avoid column id collision, the id reserved for columns has the most
significant bit set to 1. And the RegionMetadataBuilder would check the
uniqueness of the column id.
chore: Rebase develop and fix compile error
feat: add internal schema to region schema
feat: Add SchemaBuilder to build Schema
feat: Store row key end in region schema metadata
Also move the arrow schema construction to region::schema mod
feat: Add SstSchema
refactor: Replace MemtableSchema by RegionSchema
Now when writing sst files, we could use the arrow schema from our sst
schema, which contains the internal columns.
feat: Use SstSchema to read parquet
Adds user_column_end to metadata. When reading parquet file,
converts the arrow schema into SstSchema, then uses the row_key_end
and user_column_end to find out row key parts, value parts and internal
columns, instead of using the timestamp index, which may yields
incorrect index if we don't put the timestamp at the end of row key.
Move conversion from Batch to arrow Chunk to SstSchema, so SST mod doesn't
need to care the order of key, value and internal columns.
test: Add test for Value to serde_json::Value
feat: Add RawRegionMetadata to persist RegionMetadata
test: Add test to RegionSchema
fix: Fix clippy
To fix clippy::enum_clike_unportable_variant lint, define the column id
offset in ReservedColumnType and compute the final column id in
ReservedColumnId's const method
refactor: Move batch/chunk conversion to SstSchema
The parquet ChunkStream now holds the SstSchema and use its method to
convert Chunk into Batch.
chore: Address CR comment
Also add a test for pushing internal column to RegionMetadataBuilder
