QueryRewriter

- **Optimization**: Use the timing information to identify bottlenecks and optimize the query rewriting logic. ### Example with Profiling You can use `cProfile` to profile the entire process: ```python import cProfile import pstats def …

futures = {executor.submit(self.rewrite_query, query): query for query in queries} for future in as_completed(futures): rewritten_queries.append(future.result()) return rewritten_queries …

return rewritten_queries def consume_queries(channel, queue_name): def callback(ch, method, properties, body): query = body.decode('utf-8') rewriter = QueryRewriter() rewritten_query = rewriter.rewrite_q…

4. **Profiling**: Identify bottlenecks using profiling tools. ### Updated Code with Parallel Processing and Batch Handling Here's an updated version of your code that incorporates parallel processing and batch handling: ```python import …

rewritten_queries.extend(future.result()) return rewritten_queries def _process_batch(self, batch: List[str]) -> List[str]: rewritten_batch = [] for query in batch: rewritten_query =…

def expand_query(self, query): for pattern, replacement in self.rules: query = re.sub(pattern, replacement, query) return query # Example usage: rewriter = QueryRewriter() query = "SELECT * FROM table WHERE …

query = self.sanitize_query(query) query = self.apply_keyword_substitution(query) query = self.apply_pattern_matching(query) query = self.apply_contextual_expansion(query) return query def saniti…

[Turn 9905] Assistant: Certainly! The `QueryParseError` you're encountering seems to be triggered by certain special characters in the input query. To address this issue and improve the robustness of your query rewriting pipeline, you can t…

# Example usage: rewriter = QueryRewriter() query = "SELECT * FROM table WHERE condition AND column = value" rewritten_query = rewriter.rewrite_query(query) print(f"Rewritten Query: {rewritten_query}") ``` ### Explanation 1. **Keyword Sub…

raise QueryParseError(f"Error rewriting query: {query} - {e}") def expand_query(self, query): query = self.sanitize_query(query) query = self.apply_keyword_substitution(query) query = self.apply_patt…

results = [rewriter.rewrite_query(query) for query in queries] for result in results: print(f"Rewritten Query: {result}") ``` ### 3. **Efficient Data Structures** Use efficient data structures to store and manipulate query components. …
