Technical Solution: Support for IN clause in streaming SQL

This document outlines the technical solution for adding IN clause support to Dozer's streaming SQL, covering both static list lookups and subquery lookups.

Root Cause Analysis

Currently, Dozer's SQL parser and execution engine lack specific operators or logic to handle the IN clause. The existing WHERE clause processing primarily focuses on binary comparisons (=, >, <, etc.) and logical operators (AND, OR, NOT). The IN operator, especially with a subquery, introduces a new challenge: managing a potentially dynamic set of values for comparison, which requires stateful processing similar to a JOIN.

Architecture Design

The solution will involve modifications across several components of Dozer:

1. SQL Parser (dozer-sql crate):

   • Extend the SQL parser to recognize and parse IN expressions, differentiating between static lists and subqueries.
   • Represent these IN expressions in the Abstract Syntax Tree (AST).

2. Logical Plan Builder (dozer-sql crate):

   • Translate the IN AST nodes into appropriate logical plan operators.
   • For static lists: Introduce a new InList logical operator or extend an existing filter operator to handle a set of values.
   • For subqueries: Transform the IN (SELECT ...) into a JOIN operation, specifically a semi-join or inner join followed by distinct projection, as suggested in the issue description. This will leverage the existing join infrastructure.

3. Execution Plan Builder (dozer-core / dozer-sql crates):

   • Map the logical plan operators to physical execution operators.
   • For static lists: Implement a new InFilter physical operator that efficiently checks membership against a pre-defined set of values. This operator will adhere to the specified WHERE clause behavior for INSERT, UPDATE, and DELETE operations.
   • For subqueries: The transformation to JOIN in the logical plan will naturally lead to using existing Join physical operators.

4. Data Structures and Utilities:

   • Potentially introduce new data structures for efficient set lookups (e.g., HashSet) within the InFilter operator.
   • Ensure proper handling of data types for comparison.

Detailed Design for Static IN List

• Parser: The sqlparser library, which Dozer uses, already supports parsing IN expressions. We need to ensure our AST conversion correctly captures the column and the list of values.
• Logical Plan: A new LogicalOperator::Filter variant or a dedicated LogicalOperator::InList will be introduced. This operator will hold the expression for the column and the list of ScalarValues.
• Physical Plan: A new InFilterOperator will be implemented.
  • It will store the static list of values (e.g., in a HashSet for O(1) average lookup).
  • When an Operation (INSERT, UPDATE, DELETE) arrives:
    • It will extract the relevant column value(s).
    • It will apply the IN condition check.
    • It will emit Operations downstream according to the specified WHERE clause behavior:
      • INSERT: Propagate if new value matches.
      • UPDATE:
        • prev matches, new matches -> UPDATE
        • prev doesn't match, new matches -> INSERT
        • prev matches, new doesn't match -> DELETE
        • prev doesn't match, new doesn't match -> No action
      • DELETE: Propagate if previous value matches.

Detailed Design for IN Subquery

• Parser: The sqlparser library also supports IN (SELECT ...). The AST will represent this as an InSubquery expression.
• Logical Plan: This is the most critical part. The InSubquery will be transformed into a SemiJoin or an InnerJoin followed by a Distinct projection.
  • The outer query's table will be the left side of the join.
  • The subquery's result will be the right side of the join.
  • The join condition will be outer_column = subquery_column.
  • A SemiJoin is ideal as it only returns rows from the left side that have a match in the right side, without duplicating rows from the left side. If SemiJoin is not directly available or easily implementable, an InnerJoin followed by a Distinct operator on the outer query's columns would achieve a similar effect.
  • The existing Join operator in Dozer already handles the state management and propagation of changes from both sides, which is exactly what's needed for a dynamic IN list.

Implementation Plan

1. Identify relevant files:

   • dozer-sql/src/sql_analyzer/mod.rs: For SQL parsing and AST conversion.
   • dozer-sql/src/sql_analyzer/expressions.rs: For AST expression definitions.
   • dozer-sql/src/sql_analyzer/planner.rs: For logical plan generation.
   • dozer-sql/src/pipeline/builder.rs: For physical plan generation.
   • dozer-core/src/processor.rs: For defining new processor traits/implementations.
   • dozer-core/src/operators/filter.rs: Potentially extend or create a new filter operator.
   • dozer-core/src/operators/join.rs: Leverage existing join logic for subqueries.
   • dozer-sql/src/tests/: Add new tests.

2. Step 1: Static IN List Support

   • Modify dozer-sql/src/sql_analyzer/expressions.rs to add an InList variant to Expression.
   • Update dozer-sql/src/sql_analyzer/mod.rs to parse IN (value1, value2, ...) into the new InList expression.
   • Modify dozer-sql/src/sql_analyzer/planner.rs to translate InList into a LogicalOperator::Filter with a new FilterExpression::InList.
   • Implement a new physical operator, InFilterOperator, in dozer-core/src/operators/filter.rs (or a new file). This operator will handle the stateful filtering logic as described above.
   • Integrate InFilterOperator into the physical plan builder in dozer-sql/src/pipeline/builder.rs.
   • Add comprehensive unit and integration tests for static IN lists.

3. Step 2: IN Subquery Support

   • Modify dozer-sql/src/sql_analyzer/expressions.rs to add an InSubquery variant to Expression, holding the subquery's Query AST.
   • Update dozer-sql/src/sql_analyzer/mod.rs to parse IN (SELECT ...) into the new InSubquery expression.
   • Crucially, modify dozer-sql/src/sql_analyzer/planner.rs to transform InSubquery into a LogicalOperator::Join. This will involve:
     • Identifying the column from the outer query.
     • Planning the subquery as a separate logical plan.
     • Creating a JoinType::Semi (or Inner + Distinct) join between the outer query's source and the subquery's result, with the appropriate join condition.
   • Ensure the existing Join physical operator can handle the generated logical plan.
   • Add comprehensive unit and integration tests for IN subqueries.

Testing Verification Steps

A comprehensive test suite will be developed to ensure correctness.

Unit Tests

• SQL Parsing:
  • Test various IN list formats: IN (1, 2, 3), IN ('a', 'b'), IN (NULL, 1), IN (1 + 1, 3).
  • Test IN subquery parsing: IN (SELECT id FROM other_table), IN (SELECT col FROM another_table WHERE condition).
  • Test NOT IN (if NOT is supported for other operators, it should also apply here).
• Logical Plan Generation:
  • Verify that static IN lists are translated into a Filter operator with the correct InList expression.
  • Verify that IN subqueries are translated into a Join operator (specifically, a SemiJoin or InnerJoin + Distinct) with the correct join condition and sources.
• InFilterOperator Logic (for static lists):
  • Test INSERT operations:
    • Value matches IN list -> INSERT propagated.
    • Value does not match IN list -> No action.
  • Test UPDATE operations:
    • prev matches, new matches -> UPDATE propagated.
    • prev doesn't match, new matches -> INSERT propagated.
    • prev matches, new doesn't match -> DELETE propagated.
    • prev doesn't match, new doesn't match -> No action.
  • Test DELETE operations:
    • Value matches IN list -> DELETE propagated.
    • Value does not match IN list -> No action.
  • Test with various data types (integers, strings, booleans, nulls).

Integration Tests (End-to-End)

• Static IN List:
  • Create a source table.
  • Define a Dozer query using WHERE column IN (value1, value2, ...).
  • Insert, update, and delete records into the source table and verify the output of the Dozer query matches the expected streaming behavior.
  • Example: SELECT * FROM users WHERE id IN (1, 3, 5);
    • INSERT {id: 1, name: "Alice"} -> INSERT {id: 1, name: "Alice"}
    • INSERT {id: 2, name: "Bob"} -> No output
    • UPDATE {id: 1, name: "Alice"} -> {id: 1, name: "Alicia"} -> UPDATE {id: 1, name: "Alice"} -> {id: 1, name: "Alicia"}
    • UPDATE {id: 2, name: "Bob"} -> {id: 2, name: "Bobby"} -> No output
    • UPDATE {id: 2, name: "Bobby"} -> {id: 3, name: "Charlie"} -> INSERT {id: 3, name: "Charlie"}
    • UPDATE {id: 1, name: "Alicia"} -> {id: 2, name: "Bob"} -> DELETE {id: 1, name: "Alicia"}
    • DELETE {id: 3, name: "Charlie"} -> DELETE {id: 3, name: "Charlie"}
• IN Subquery:
  • Create two source tables: main_table and lookup_table.
  • Define a Dozer query using WHERE column IN (SELECT sub_column FROM lookup_table WHERE ...).
  • Perform operations on both main_table and lookup_table and verify the output.
  • Example: SELECT * FROM orders WHERE customer_id IN (SELECT id FROM premium_customers WHERE region = 'EU');
    • INSERT {id: 1, name: "Alice", region: "EU"} into premium_customers.
      • Expected: Any existing orders with customer_id = 1 should now be emitted as INSERTs.
    • INSERT {order_id: 101, customer_id: 1, amount: 100} into orders.
      • Expected: If customer_id = 1 is in premium_customers (and region = 'EU'), INSERT {order_id: 101, customer_id: 1, amount: 100} is emitted.
    • DELETE {id: 1, name: "Alice", region: "EU"} from premium_customers.
      • Expected: Any existing orders with customer_id = 1 should now be emitted as DELETEs.
    • UPDATE {id: 1, name: "Alice", region: "EU"} -> {id: 1, name: "Alice", region: "US"} in premium_customers.
      • Expected: Any existing orders with customer_id = 1 should now be emitted as DELETEs (because region no longer matches).
  • Test edge cases like empty subquery results, subquery results changing over time.

This structured approach ensures that both forms of the IN clause are correctly parsed, planned, and executed, adhering to the specified streaming semantics.
