From f201c0afb802ae4b8d89c81dffb6d67da27979b0 Mon Sep 17 00:00:00 2001 From: Nivedha Palani Date: Mon, 6 Apr 2026 00:45:19 +0530 Subject: [PATCH] feat: Implement Advanced Data Operations Framework - Add comprehensive bulk operations namespace with core interfaces - Implement streaming CSV and JSON data readers with robust parsing - Add progress tracking infrastructure with rich console output - Create bulk import command with validation and error handling - Add bulk export functionality with multiple format support - Implement resilient bulk processor with parallel execution - Add data validation framework with configurable rules - Create comprehensive test suite for all components - Support for large datasets with memory-efficient streaming - Rich CLI integration with progress reporting and error handling This framework provides enterprise-grade bulk data operations with streaming support, parallel processing, and comprehensive error handling. Addresses critical user needs for importing/exporting large datasets efficiently and reliably. --- BulkOperationsTest/BulkOperationsTest.csproj | 10 + BulkOperationsTest/Program.cs | 151 ++++++ simple_test.cs | 152 ++++++ src/BulkOperations/Core/BulkDataProcessor.cs | 232 +++++++++ .../Exporters/CsvDataExporter.cs | 139 ++++++ .../Exporters/JsonDataExporter.cs | 118 +++++ .../Interfaces/IBulkOperations.cs | 136 ++++++ src/BulkOperations/Models/BulkModels.cs | 98 ++++ src/BulkOperations/Models/ValidationModels.cs | 99 ++++ .../Progress/ConsoleProgressReporter.cs | 181 +++++++ .../Progress/MemoryProgressTracker.cs | 132 +++++ src/BulkOperations/Readers/CsvDataReader.cs | 282 +++++++++++ src/BulkOperations/Readers/JsonDataReader.cs | 263 ++++++++++ .../Validators/BasicDataValidator.cs | 390 +++++++++++++++ src/Commands/DataExportCommand.cs | 453 ++++++++++++++++++ src/Commands/DataImportCommand.cs | 422 ++++++++++++++++ src/Program.cs | 14 + test_data.csv | 6 + test_data.json | 26 + test_users.csv | 5 + tests/BulkOperationsTests.cs | 308 ++++++++++++ tests/BulkOperationsTests.csproj | 14 + tests/TestRunner.cs | 22 + 23 files changed, 3653 insertions(+) create mode 100644 BulkOperationsTest/BulkOperationsTest.csproj create mode 100644 BulkOperationsTest/Program.cs create mode 100644 simple_test.cs create mode 100644 src/BulkOperations/Core/BulkDataProcessor.cs create mode 100644 src/BulkOperations/Exporters/CsvDataExporter.cs create mode 100644 src/BulkOperations/Exporters/JsonDataExporter.cs create mode 100644 src/BulkOperations/Interfaces/IBulkOperations.cs create mode 100644 src/BulkOperations/Models/BulkModels.cs create mode 100644 src/BulkOperations/Models/ValidationModels.cs create mode 100644 src/BulkOperations/Progress/ConsoleProgressReporter.cs create mode 100644 src/BulkOperations/Progress/MemoryProgressTracker.cs create mode 100644 src/BulkOperations/Readers/CsvDataReader.cs create mode 100644 src/BulkOperations/Readers/JsonDataReader.cs create mode 100644 src/BulkOperations/Validators/BasicDataValidator.cs create mode 100644 src/Commands/DataExportCommand.cs create mode 100644 src/Commands/DataImportCommand.cs create mode 100644 test_data.csv create mode 100644 test_data.json create mode 100644 test_users.csv create mode 100644 tests/BulkOperationsTests.cs create mode 100644 tests/BulkOperationsTests.csproj create mode 100644 tests/TestRunner.cs diff --git a/BulkOperationsTest/BulkOperationsTest.csproj b/BulkOperationsTest/BulkOperationsTest.csproj new file mode 100644 index 0000000..2150e37 --- /dev/null +++ b/BulkOperationsTest/BulkOperationsTest.csproj @@ -0,0 +1,10 @@ +ο»Ώ + + + Exe + net8.0 + enable + enable + + + diff --git a/BulkOperationsTest/Program.cs b/BulkOperationsTest/Program.cs new file mode 100644 index 0000000..958201f --- /dev/null +++ b/BulkOperationsTest/Program.cs @@ -0,0 +1,151 @@ +ο»Ώusing System;
