+# Apache Tika End-to-End Tests
+
+End-to-end integration tests for Apache Tika components.
+
+## Overview
+
+This module contains standalone end-to-end (E2E) tests for various Apache Tika
distribution formats and deployment modes. Unlike unit and integration tests in
the main Tika build, these E2E tests validate complete deployment scenarios
using Docker containers and real-world test data.
+
+**Note:** This module is included in the main Tika build under the `e2e` Maven
profile (`-Pe2e`). Run `mvn test -Pe2e` from the repo root to execute these
tests.
+
+## Test Modules
+
+- **tika-grpc** - E2E tests for tika-grpc server
+
+## Prerequisites
+
+- Java 17 or later
+- Maven 3.6 or later
+- Docker and Docker Compose
+- Internet connection (for downloading test documents)
+
Review Comment:
Fixed — Docker and Docker Compose are now listed as optional prerequisites,
only needed when running in Docker Compose mode (tika.e2e.useLocalServer=false).

> # Replace H2 SQL engine with Calcite-based SQL engine
> # Maintain all existing functionality for config store
> # Update API calls to match Ignite 3.x breaking changes
> # Ensure backward compatibility for stored configurations (if possible)
> h2. Benefits
> * Modern SQL engine with Apache Calcite
> * Better performance and query optimization
> * Active maintenance and future support
> * Improved SQL feature set
> * No dependency on old H2 1.4.x (2018)
> h2. Breaking Changes to Address
> * Ignite 3.x has major API changes from 2.x
> * Configuration format changes
> * Cache API differences
> * SQL query API updates
> * Client connection changes
> h2. Implementation Steps
> # Research Ignite 3.x API changes and migration guide
> # Update Maven dependencies to Ignite 3.x
> # Refactor {{IgniteConfigStore}} to use new Ignite 3.x API
> # Update {{IgniteStoreServer}} for new connection model
> # Modify SQL queries if needed for Calcite compatibility
> # Update configuration handling
> # Update tests to work with Ignite 3.x
> # Test backward compatibility with existing configs
> # Update documentation
> h2. Acceptance Criteria
> * Ignite upgraded to version 3.x (latest stable)
> * Uses Calcite SQL engine instead of H2
> * All existing tests pass
> * Config store functionality preserved
