Exasol Driver 0.12.0¶
Driver Version 0.12.0 Release Date 2026-04-30 Tested With Exasol 2025
This driver provides access to Exasol , an in-memory analytics engine. It is developed by Exasol Labs. The source code can be found at exarrow-rs ; the ADBC Driver Foundry distributes precompiled binaries of the upstream sources for Linux, macOS, and Windows.
Note
This page provides some ADBC-specific documentation. For full documentation and examples, see the upstream repository: https://github.com/exasol-labs/exarrow-rs .
Installation¶
The Exasol driver can be installed with dbc :
dbc install exasol
Connecting¶
To use the driver, provide the URI of an Exasol database as the uri option.
from adbc_driver_manager import dbapi
conn = dbapi.connect(
driver="exasol",
db_kwargs={
"uri": "exasol://user:pass@localhost:8563/?tls=true&validateservercertificate=0",
}
)
Full documentation for the connection string format can be found at exarrow-rs .
Note: The example above is for Python using the adbc-driver-manager package but the process will be similar for other driver managers. See adbc-quickstarts .
