- refactor `AddPrimaryKeyToDDL` to accurately locate the closing parenthesis of column definitions, ensuring `PRIMARY KEY` is inserted before any table options like `WITH` clauses (fixes #694) - previously, the primary key could be incorrectly appended inside the `WITH` clause, resulting in invalid SQL DDL test(replication): add test for custom table_ddl with primary key and with clause - introduce `r.88.table_ddl_with_clause.yaml` to validate the fix for GitHub Issue #694 in an end-to-end replication scenario - verify that the target table is created with the specified primary key and table options (e.g., `DATA_COMPRESSION`) - add comprehensive unit tests for `AddPrimaryKeyToDDL` covering DDLs with and without `WITH` clauses, nested parentheses, and different dialects
- introduce `definition-only` mode for creating table and file definitions without data - support `definition-only` mode for database targets (e.g., postgres to mssql) - support `definition-only` mode for file targets (e.g., postgres to parquet/arrow) - inject `WHERE 1=0` into source queries to prevent data transfer - skip empty buffer check for file writes in `definition-only` mode - add validation for file targets, restricting to parquet and arrow formats - add cli tests for database and file targets - add cli test for `definition-only` failure with csv file target
…ust caching logic
- introduce `db2` type in `dbio` for specific DB2 handling - add `db2.yaml` template with core SQL operations and metadata queries - implement `GetType` method in `connection` to return more accurate type for ODBC connections - update `connection_local` to use `GetType` for better connection descriptions - modify `database` package to use `Template().Quote` for consistent quoting - enhance `GenerateDDL` to support `partition by`, `cluster by`, `distkey`, `sortkey`, and `primary key` clauses - update `GenerateMergeConfig` to include `src_insert_fields`, `tgt_fields`, and `placeholder_fields` for merge statements - adjust `GetOptimizeTableStatements` for column type optimization using `Template().Quote` - update `CompareChecksums` to use `Template().Quote` for field quoting - modify `AddMissingColumns` to use `Template().Quote` for column quoting - update `dbio_types` to support `column_upper` variable from templates for case normalization - add `TestSuiteDatabaseDB2` to run tests for DB2 database - update `go.mod` and `go.sum` for `godbc` dependency

When streaming data from Prometheus with large time ranges (> 1 hour), the StreamRowsChunked function would stall after ~100 rows. This was caused by the bwRows channel (buffer size 100) filling up because processBwRows goroutine was never started. The issue occurred because StreamRowsChunked creates a datastream with NewDatastreamContext() and pushes rows directly, bypassing Start() which normally starts the processBwRows goroutine. Changes: - Add StartBwProcessor() public method to Datastream to start the bytes-written processor independently - Call StartBwProcessor() in StreamRowsChunked before pushing rows This ensures the bwRows channel is drained, preventing the producer from blocking when the buffer fills up.
