+  For Linux and macOS, you can easily download pre-built binaries that are ready to use. In most cases, downloading the version without PyO3 is sufficient. However, if you plan to run scripts in CPython (and use Python packages like NumPy and Pandas), you will need to download the version with PyO3 and install a Python with the same version as the Python in the PyO3 version. We recommend using virtualenv for the installation process to manage multiple Python versions.

docs/how-to/how-to-implement-sql-statement.md

@@ -0,0 +1,74 @@
+This document introduces how to implement SQL statements in GreptimeDB.
+
+The execution entry point for SQL statements locates at Frontend Instance. You can see it has
+implemented `SqlQueryHandler`:
+
+```rust
+impl SqlQueryHandler for Instance {
+    type Error = Error;
+
+    async fn do_query(&self, query: &str, query_ctx: QueryContextRef) -> Vec<Result<Output>> {
+        // ...
+    }
+}
+```
+
+Normally, when a SQL query arrives at GreptimeDB, the `do_query` method will be called. After some parsing work, the SQL
+will be feed into `StatementExecutor`:
+
+```rust
+// in Frontend Instance:
+self.statement_executor.execute_sql(stmt, query_ctx).await
+```
+
+That's where we handle our SQL statements. You can just create a new match arm for your statement there, then the
+statement is implemented for both GreptimeDB Standalone and Cluster. You can see how `DESCRIBE TABLE` is implemented as
+an example.
+
+Now, what if the statements should be handled differently for GreptimeDB Standalone and Cluster? You can see there's
+a `SqlStatementExecutor` field in `StatementExecutor`. Each GreptimeDB Standalone and Cluster has its own implementation
+of `SqlStatementExecutor`. If you are going to implement the statements differently in the two mode (
+like `CREATE TABLE`), you have to implement them in their own `SqlStatementExecutor`s.
+
+Summarize as the diagram below:
+
+```text
+                             SQL query

+```
+
+Note that some SQL statements can be executed in our QueryEngine, in the form of `LogicalPlan`. You can follow the
+invocation path down to the `QueryEngine` implementation from `StatementExecutor::plan_exec`. For now, there's only
+one `DatafusionQueryEngine` for both GreptimeDB Standalone and Cluster. That lone query engine works for both modes is
+because GreptimeDB read/write data through `Table` trait, and each mode has its own `Table` implementation.
+
+We don't have any bias towards whether statements should be handled in query engine or `StatementExecutor`. You can
+implement one kind of statement in both places. For example, `Insert` with selection is handled in query engine, because
+we can easily do the query part there. However, `Insert` without selection is not, for the cost of parsing statement
+to `LogicalPlan` is not neglectable. So generally if the SQL query is simple enough, you can handle it
+in `StatementExecutor`; otherwise if it is complex or has some part of selection, it should be parsed to `LogicalPlan`
+and handled in query engine.

+Feature Name: "File external table"
+Tracking Issue: https://github.com/GreptimeTeam/greptimedb/issues/1041
+Date: 2023-03-08

+
+File external table
+
+---
+
+# Summary
+
+Allows users to perform SQL queries on files
+
+# Motivation
+
+User data may already exist in other storages, i.g., file systems/s3, etc. in CSV, parquet, JSON format, etc. We can provide users the ability to perform SQL queries on these files.
+
+
+# Details
+
+## Overview
+
+The file external table providers users ability to perform SQL queries on these files.
+
+For example, a user has a CSV file on the local file system `/var/data/city.csv`:
+
+```
+Rank , Name , State , 2023 Population , 2020 Census , Annual Change , Density (mi²)
+1 , New York City , New York , 8,992,908 , 8,804,190 , 0.7% , 29,938
+2 , Los Angeles , California , 3,930,586 , 3,898,747 , 0.27% , 8,382
+3 , Chicago , Illinois , 2,761,625 , 2,746,388 , 0.18% , 12,146
+.....
+```
+
+Then user can create a file external table with:
+
+```sql
+CREATE EXTERNAL TABLE city with(location='/var/data/city.csv', format="CSV", field_delimiter = ',', record_delimiter = '\n', skip_header = 1);
+```
+
+Then query the external table with:
+
+```bash
+MySQL> select * from city;
+```
+
+| Rank | Name          | State      | 2023 Population | 2020 Census | Annual Change | Density (mi²) |
+| :--- | :------------ | :--------- | :-------------- | :---------- | :------------ | :------------ |
+| 1    | New York City | New York   | 8,992,908       | 8,804,190   | 0.7%          | 29,938        |
+| 2    | Los Angeles   | California | 3,930,586       | 3,898,747   | 0.27%         | 8,382         |
+| 3    | Chicago       | Illinois   | 2,761,625       | 2,746,388   | 0.18%         | 12,146        |
+
+Drop the external table, if needs with:
+
+```sql
+DROP EXTERNAL TABLE city
+```
+
+
+### Syntax
+
+```
+CREATE EXTERNAL [<database>.]<table_name>
+[
+ (
+    <col_name> <col_type> [NULL | NOT NULL] [COMMENT "<comment>"]
+ )
+]
+[ WITH
+ (
+     LOCATION = 'url'
+   [,FIELD_DELIMITER =  'delimiter' ]
+   [,RECORD_DELIMITER =  'delimiter' ]
+   [,SKIP_HEADER =  '<number>' ]
+   [,FORMAT =  { csv | json | parquet } ]
+   [,PATTERN = '<regex_pattern>' ]
+   [,ENDPOINT = '<uri>' ]
+   [,ACCESS_KEY_ID = '<key_id>' ]
+   [,SECRET_ACCESS_KEY = '<access_key>' ]
+   [,SESSION_TOKEN = '<token>' ]
+   [,REGION = '<region>' ]
+   [,ENABLE_VIRTUAL_HOST_STYLE = '<boolean>']
+   ..
+ )
+]
+```
+
+### Supported File Format
+
+The external file table supports multiple formats; We divide formats into row format and columnar format.
+
+Row formats:
+
+- CSV, JSON
+
+Columnar formats:
+
+- Parquet
+
+Some of these formats support filter pushdown, and others don't. If users use very large files, that format doesn't support pushdown, which might consume a lot of IO for scanning full files and cause a long running query.
+
+### File Table Engine
+
+![overview](external-table-engine-overview.png)
+
+We implement a file table engine that creates an external table by accepting user-specified file paths and treating all records as immutable.
+
+1. File Format Decoder: decode files to the `RecordBatch` stream.
+2. File Table Engine: implement the `TableProvider` trait, store necessary metadata in memory, and provide scan ability.
+
+Our implementation is better for small files. For large files(i.g., a GB-level CSV file), suggests our users import data to the database.
+
+## Drawbacks
+
+- Some formats don't support filter pushdown
+- Hard to support indexing
+
+## Life cycle
+
+### Register a table
+
+1. Write metadata to manifest.
+2. Create the table via file table engine.
+3. Register table to `CatalogProvider` and register table to `SystemCatalog`(persist tables to disk).
+
+### Deregister a table (Drop a table)
+
+1. Fetch the target table info (figure out table engine type).
+2. Deregister the target table in `CatalogProvider` and `SystemCatalog`.
+3. Find the target table engine.
+4. Drop the target table.
+
+### Recover a table when restarting
+
+1. Collect tables name and engine type info.
+2. Find the target tables in different engines.
+3. Open and register tables.
+
+# Alternatives
+
+## Using DataFusion API
+
+We can use datafusion API to register a file table:
+
+```rust
+let ctx = SessionContext::new();
+
+ctx.register_csv("example", "tests/data/example.csv", CsvReadOptions::new()).await?;
+
+// create a plan
+let df = ctx.sql("SELECT a, MIN(b) FROM example WHERE a <= b GROUP BY a LIMIT 100").await?;
+```
+
+### Drawbacks
+
+The DataFusion implements its own `Object Store` abstraction and supports parsing the partitioned directories, which can push down the filter and skips some directories. However, this makes it impossible to use our's `LruCacheLayer`(The parsing of the partitioned directories required paths as input). If we want to manage memory entirely, we should implement our own `TableProvider` or `Table`.
+
+- Impossible to use `CacheLayer`
+
+## Introduce an intermediate representation layer
+
+![overview](external-table-engine-way-2.png)
+
+We convert all files into `parquet` as an intermediate representation. Then we only need to implement a `parquet` file table engine, and we already have a similar one. Also, it supports limited filter pushdown via the `parquet` row group stats.
+
+### Drawbacks
+
+- Computing overhead
+- Storage overhead
+
