+title: Faster ADBC drivers for BigQuery, MySQL, SQL Server, and Trino
+author: ADBC Drivers Contributors
+---
+
+Today the ADBC Drivers Contributors released updated drivers for four database systems, available immediately via [dbc](https://docs.columnar.tech/dbc/). To update, just `dbc install <driver>` to get the latest version.
+
+## Updated Drivers
+
+The main highlight for all drivers is improved performance. Each newly released driver is now significantly faster than its previous release and is typically faster than or on par with its reference non-ADBC driver, with some variation depending on workload and data types such as strings.
+
+### Google BigQuery driver version 1.11.0
+
+- Improved query performance by identifying and patching an issue in the Google BigQuery SDK for Go. [#102](https://github.com/adbc-drivers/bigquery/pull/102)
+- Added experimental support for bulk ingest via the Storage Write API, instead of by uploading Parquet files. This is still a work in progress and is not recommended for production use. [#105](https://github.com/adbc-drivers/bigquery/pull/105)
+
+### MySQL driver version 0.3.0
+
+- Improved bulk ingest performance. [#66](https://github.com/adbc-drivers/mysql/pull/66)
+
+### Microsoft SQL Server driver version 1.3.0
+
+- Improved query performance by identifying and submitting fixes for [microsoft/go-mssqldb](https://github.com/microsoft/go-mssqldb).
+
+### Trino driver version 0.3.0
+
+- Improved bulk ingest performance. [#58](https://github.com/adbc-drivers/trino/pull/58)
+
+## Benchmarks
+
+Query benchmarks measure the time to retrieve a PyArrow Table, while ingest benchmarks measure the time to write a PyArrow Table.  The benchmark harness in all cases uses Python.
+
+### Querying Data
+
+| Database | Data Size | ADBC Before (s) | ADBC After (s) | Competitor (s) | Relative Time[^speedup] |
+| :-- | :-- | --: | --: | --: | --: |
+| BigQuery | 6 million rows | 95.2 ± 2.34 | **31.0 ± 2.1** | 56.4 ± 1.3[^bigquery] | 0.55x |
+| SQL Server | 1.2 million rows | 9.6 ± 0.1 | 3.3 ± 0.0 | **3.0 ± 0.2**[^mssql] | 1.1x |
+
+[^bigquery]: python-bigquery-sqlalchemy with Storage Read API enabled
+[^mssql]: turbodbc 5.1.2 + msodbcsql 18.6.1.1-1
+[^speedup]: Versus competitor. Lower is better.
+
+### Ingesting Data
+
+| Database | Data Size | ADBC Before (s) | ADBC After (s) | Competitor (s) | Relative Time[^speedup] |
+| :-- | :-- | --: | --: | --: | --: |
+| MySQL | 600k rows | 467.8 ± 17.9 | **6.7 ± 0.3** | 13.1 ± 0.7[^mysql] | 0.51x |
+| Trino | 60k rows | 1962.8 ± 182.2 | **52.2 ± 8.2** | 2061.8 ± 15.1[^trino] | 0.03x |
+
+[^mysql]: mysql-connector-python using DuckDB to convert Arrow data to Python objects; using PyArrow `Table.to_pylist` instead, timing was 15.31 ± 0.59s
+[^trino]: trino-python-client
