fix(csharp): remove Foundry drivers from solution (#4323)
Removes the following drivers from the solution (but not yet from the
repo):
- Apache - moved to
https://github.com/adbc-drivers/hiveserver2/tree/main/csharp
- BigQuery - moved to
https://github.com/adbc-drivers/bigquery/tree/main/csharp
- Databricks - moved to
https://github.com/adbc-drivers/databricks/tree/main/csharp
- FlightSQL - displaced by the interop library

-# Databricks CloudFetch E2E Benchmark
-
-Real end-to-end benchmark for measuring memory usage and performance of the
Databricks CloudFetch implementation against an actual Databricks cluster.
-
-## Overview
-
-This benchmark tests the complete CloudFetch flow with real queries against a
Databricks warehouse:
-- Full end-to-end CloudFetch flow (query execution, downloads, LZ4
decompression, batch consumption)
-- Real data from Databricks tables
-- Memory usage with actual network I/O
-- Power BI consumption simulation with batch-proportional delays
-
-## Benchmark
-
-### CloudFetchRealE2EBenchmark
-
-**Real end-to-end benchmark against actual Databricks cluster:**
-
-**Parameters:**
-- `ReadDelayMs`: Fixed at 5ms per 10K rows to simulate Power BI processing
delays
-
-**Method:**
-- `ExecuteLargeQuery`: Executes the query specified in the config file, reads
all batches with Power BI-like processing delays
-
-**Prerequisites:**
-- Set `DATABRICKS_TEST_CONFIG_FILE` environment variable pointing to your
config JSON
-- Config file must contain:
- - `uri`: Full Databricks warehouse URI (e.g.,
`https://hostname/sql/1.0/warehouses/xxx`)
- - `token`: Databricks access token
- - `query`: SQL query to execute (this will be run by the benchmark)
-
-## Running the Benchmark
-
-### Run the CloudFetch E2E benchmark on .NET 8.0:
-```bash
-cd csharp
-export DATABRICKS_TEST_CONFIG_FILE=/path/to/databricks-config.json
-dotnet run -c Release --project Benchmarks/Benchmarks.csproj --framework
net8.0 -- --filter "*CloudFetchRealE2E*"
-```
-
-### Run the CloudFetch E2E benchmark on .NET Framework 4.7.2 (Windows only,
simulates Power BI):
-```powershell
-cd csharp
-$env:DATABRICKS_TEST_CONFIG_FILE="C:\path\to\databricks-config.json"
-dotnet run -c Release --project Benchmarks/Benchmarks.csproj --framework
net472 -- --filter "*CloudFetchRealE2E*"
-```
-
-**Note**: .NET Framework 4.7.2 is only available on Windows. This target is
useful for testing CloudFetch behavior in Power BI-like environments, as Power
BI Desktop runs on .NET Framework 4.7.2.
-
-### Real E2E Benchmark Configuration
-
-Create a JSON config file with your Databricks cluster details:
-
-```json
-{
- "uri": "https://your-workspace.cloud.databricks.com/sql/1.0/warehouses/xxx";,
- "token": "dapi...",
- "query": "select * from main.tpcds_sf1_delta.catalog_sales",
- "type": "databricks"
-}
-```
-
-Then set the environment variable:
-```bash
-export DATABRICKS_TEST_CONFIG_FILE=/path/to/databricks-config.json
-```
-
-**Note**: The `query` field specifies the SQL query that will be executed
during the benchmark. Use a query that returns a large result set to properly
test CloudFetch performance.
-
-## Understanding the Results
-
-### Key Metrics:
-
-- **Peak Memory (MB)**: Maximum working set memory during execution
- - Displayed in the summary table via custom column
- - Printed to console output during each benchmark iteration
- - Shows the real memory footprint during CloudFetch operations
- - Stored in temp file for accurate reporting across BenchmarkDotNet processes
-
-- **Total Rows**: Total number of rows processed during the benchmark
- - Displayed in the summary table via custom column
- - Shows the actual data volume processed
-
-- **Total Batches**: Total number of Arrow RecordBatch objects processed
- - Displayed in the summary table via custom column
- - Indicates how data was chunked by CloudFetch
- - Useful for understanding batch size and network operation counts
-
-- **Allocated**: Total managed memory allocated during the operation
- - Lower is better for memory efficiency
-
-- **Gen0/Gen1/Gen2**: Number of garbage collections
- - Gen0: Frequent, low cost (short-lived objects)
- - Gen1/Gen2: Less frequent, higher cost (longer-lived objects)
- - LOH: Part of Gen2, objects >85KB
-
-- **Mean/Median**: Execution time statistics
- - Shows the end-to-end time including query execution, CloudFetch downloads,
LZ4 decompression, and batch consumption
-
-### Example Output
-
-**Console output during benchmark execution:**
-```

-**Key Metrics:**
-- **E2E Time**: 8.75-9.79 seconds (includes query execution, CloudFetch
downloads, LZ4 decompression, batch consumption)
-- **Peak Memory**: 256.48 MB (tracked via Process.WorkingSet64, displayed via
custom column)
-- **Total Rows**: 1,441,548 rows processed
-- **Total Batches**: 145 Arrow RecordBatch objects (average ~9,941 rows per
batch)
-- **Total Allocated**: 1.78 GB managed memory
-- **GC Collections**: 28K Gen0/Gen1/Gen2 collections
-
-**Note**: Metrics (Peak Memory, Total Rows, Total Batches) are stored in a
temporary JSON file (`/tmp/cloudfetch_benchmark_metrics.json` on Unix,
`%TEMP%\cloudfetch_benchmark_metrics.json` on Windows) during benchmark
execution. Custom BenchmarkDotNet columns read from this file to display
accurate values in the summary table.
