-Feature Name: Json Datatype

-Date: 2024-8-6
-Author: "Yuhan Wang <profsyb@gmail.com>"
----
-
-# Summary
-This RFC proposes a method for storing and querying JSON data in the database.
-
-# Motivation
-JSON is widely used across various scenarios. Direct support for writing and querying JSON can significantly enhance the database's flexibility.
-
-# Details
-
-## Storage and Query
-
-GreptimeDB's type system is built on Arrow/DataFusion, where each data type in GreptimeDB corresponds to a data type in Arrow/DataFusion. The proposed JSON type will be implemented on top of the existing `Binary` type, leveraging the current `datatype::value::Value` and `datatype::vectors::BinaryVector` implementations, utilizing the JSONB format as the encoding of JSON data. JSON data is stored and processed similarly to binary data within the storage layer and query engine.
-
-This approach brings problems when dealing with insertions and queries of JSON columns.
-
-## Insertion
-
-Users commonly write JSON data as strings. Thus we need to make conversions between string and JSONB. There are 2 ways to do this:
-
-1. MySQL and PostgreSQL servers provide auto-conversions between strings and JSONB. When a string is inserted into a JSON column, the server will try to parse the string as JSON and convert it to JSONB. The non-JSON strings will be rejected.
-
-2. A function `parse_json` is provided to convert string to JSONB. If the string is not a valid JSON string, the function will return an error.
-
-For example, in MySQL client:
-```SQL
-CREATE TABLE IF NOT EXISTS test (
-    ts TIMESTAMP TIME INDEX,
-    a INT,
-    b JSON
-);
-
-INSERT INTO test VALUES(
-    0,
-    0,
-    '{
-        "name": "jHl2oDDnPc1i2OzlP5Y",
-        "timestamp": "2024-07-25T04:33:11.369386Z",
-        "attributes": { "event_attributes": 48.28667 }
-    }'
-);
-
-INSERT INTO test VALUES(
-    0,
-    0,
-    parse_json('{
-        "name": "jHl2oDDnPc1i2OzlP5Y",
-        "timestamp": "2024-07-25T04:33:11.369386Z",
-        "attributes": { "event_attributes": 48.28667 }
-    }')
-);
-```
-Are both valid.
-
-The dataflow of the insertion process is as follows:
-```
-Insert JSON strings directly through client:
-                                   Parse                       Insert

-        (Server identifies JSON type and performs auto-conversion)
-
-Insert JSON strings through parse_json function:
-                                                                   Parse                     Insert

-                                            (Conversion is performed by UDF inside Query Engine)
-```
-
-Servers identify JSON column through column schema and perform auto-conversions. But when using prepared statements and binding parameters, the corresponding cached plans in datafusion generated by prepared statements cannot identify JSON columns. Under this circumstance, the servers identify JSON columns through the given parameters and perform auto-conversions.
-
-The following is an example of inserting JSON data through prepared statements:
-```Rust
-sqlx::query(
-    "create table test(ts timestamp time index, j json)",
-)
-.execute(&pool)
-.await
-.unwrap();
-
-let json = serde_json::json!({
-    "code": 200,
-    "success": true,
-    "payload": {
-        "features": [
-            "serde",
-            "json"
-        ],
-        "homepage": null
-    }
-});
-
-// Valid, can identify serde_json::Value as JSON type
-sqlx::query("insert into test values($1, $2)")
-    .bind(i)
-    .bind(json)
-    .execute(&pool)
-    .await
-    .unwrap();
-
-// Invalid, cannot identify String as JSON type
-sqlx::query("insert into test values($1, $2)")
-    .bind(i)
-    .bind(json.to_string())
-    .execute(&pool)
-    .await
-    .unwrap();
-```
-
-## Query
-
-Correspondingly, users prefer to display JSON data as strings. Thus we need to make conversions between JSON data and strings before presenting JSON data. There are also 2 ways to do this: auto-conversions on MySQL and PostgreSQL servers, and function `json_to_string`.
-
-For example, in MySQL client:
-```SQL
-SELECT b FROM test;
-
-SELECT json_to_string(b) FROM test;
-```
-Will both return the JSON as human-readable strings.
-
-Specifically, to perform auto-conversions, we attach a message to JSON data in the `metadata` of `Field` in Arrow/Datafusion schema when scanning a JSON column. Frontend servers could identify JSON data and convert it to strings.
-
-The dataflow of the query process is as follows:
-```
-Query directly through client:
-                                  Decode                            Scan
-        String(Serialized JSON)┌──────────┐Arrow Binary(JSONB)┌──────────────┐Arrow Binary(JSONB)
- Client <----------------------│  Server  │<------------------│ Query Engine │<----------------- Storage
-                               └──────────┘                   └──────────────┘
-(Server identifies JSON type and performs auto-conversion based on column metadata)
-
-Query through json_to_string function:
-                                                                   Scan & Decode
-        String(Serialized JSON)┌──────────┐String(Serialized JSON)┌──────────────┐Arrow Binary(JSONB)
- Client <----------------------│  Server  │<----------------------│ Query Engine │<----------------- Storage
-                               └──────────┘                       └──────────────┘
-                                                 (Conversion is performed by UDF inside Query Engine)
-
-```
-
-However, if a function uses JSON type as its return type, the metadata method mentioned above is not applicable. Thus the functions of JSON type should specify the return type explicitly instead of returning a JSON type, such as `json_get_int` and `json_get_float` which return corresponding data of `INT` and `FLOAT` type respectively.
-
-## Functions
-Similar to the common JSON type, JSON data can be queried with functions.
-
-For example:
-```SQL
-CREATE TABLE IF NOT EXISTS test (
-    ts TIMESTAMP TIME INDEX,
-    a INT,
-    b JSON
-);
-
-INSERT INTO test VALUES(
-    0,
-    0,
-    '{
-        "name": "jHl2oDDnPc1i2OzlP5Y",
-        "timestamp": "2024-07-25T04:33:11.369386Z",
-        "attributes": { "event_attributes": 48.28667 }
-    }'
-);
-
-SELECT json_get_string(b, 'name') FROM test;
-+---------------------+
-| b.name              |
-+---------------------+
-| jHl2oDDnPc1i2OzlP5Y |
-+---------------------+
-
-SELECT json_get_float(b, 'attributes.event_attributes') FROM test;
-+--------------------------------+
-| b.attributes.event_attributes  |
-+--------------------------------+

-And more functions can be added in the future.
-
-# Drawbacks
-
-As a general purpose JSON data type, JSONB may not be as efficient as specialized data types for specific scenarios.
-
-The auto-conversion mechanism is not supported in all scenarios. We need to find workarounds for these scenarios.
-
-# Alternatives
-
-Extract and flatten JSON schema to store in a structured format through pipeline. For nested data, we can provide nested types like `STRUCT` or `ARRAY`.
