![]() : Could not start SASL: Error in sasl_client_start (-1) SASL(-1): generic failure: GSSAPI Error: Unspecified GSS failure. DBeaver is a universal database management tool for everyone who needs to work with data in a professional way. I select the source table to extract data from into csv or sql form. Message=("Could not start SASL: %s" % ())) When using a tool like dbeaver I can connect both to the source and destination database. > conn = connect(host='hdpmaster.hadoop',port=10000,database='default',auth_mechanism='GSSAPI',kerberos_service_name='user1')įile "/usr/local/lib/python2.7/dist-packages/impala/dbapi.py", line 147, in connectįile "/usr/local/lib/python2.7/dist-packages/impala/hiveserver2.py", line 658, in connectįile "/usr/local/lib/python2.7/dist-packages/thrift_sasl/_init_.py", line 72, in open Download ZIP DBeaver password decryption script - for newer versions of DBeaver Raw decryptdbeaver. Here is the error message I see when using Impyla: > from impala.dbapi import connect ![]() I think we will hear more about DuckDB in the coming years.I have tried using the following Python libraries to connect to a kerberised Hive instance: There are a lot of people doing very interesting scenarios, like Building extremely fast and cheap ETL pipeline just using Parquet, DuckDB running on a cloud Functions. Python being a high-level language provides support for various databases. The size of the PowerBI report is only 48 KB, as I import only the results of the query not the whole 30 GB of data, yes separation of Storage and Compute make a lot of sense in this case.Īlthough the POC in this blog was just for fun, the query take 70 seconds using the ODBC driver in PowerBI ( which is still in an Alpha stage), The same query using dbeaver take 19 second using the more mature JDBC driver, and it works only with import, for Direct Query you need a custom connector and the use of the Gateway, But I see a lot of potential. In the Connection settings window, enter the host, port, username, and password. If you use MySQL 5, you would need to choose MySQL 5. Click the New Database Connection button and then select MySQL as the database. Make sure to install psycopg2-binary, because it will also take care of the dependencies required. Let’s now create a connection for our MySQL database. Just for fun, I duplicated the parquet file just to reach the 1 Billion Rows mark Method 1: Using Pandas Read SQL Query Step 1: Install a Python package to connect to your database We suggest installing the following packages: PostgreSQL database: pip install psycopg2-binary. DBeaver is very user-friendly and is very easy to get started with. DBeaver Free multi-platform database tool for developers, SQL programmers, database administrators and analysts. Select ODBC, if the driver was installed correctly, you should see an entry for DuckDBĪs of this writing there is a bug in the driver, if you add a path to the DuckDB database file, the driver will not recognise the tables and views inside it, Instead I selectedĪnd defining the base Table as a CTE, reading Directly from a folder of parquet files In fact, the python ibmdb extension is a wrapper for an underlying CLI driver (which does the real work of communicating with the database). For example will assign the httpschema property to https and port to 9999. Seamless Integrate with Pandas Photo by GraphicMama-team on Pixabay Do you think that’s all No. This GUI is cross-platform friendly, and it imports, exports, and backs up data swiftly. ![]() It is nothing different from other regular relational databases. DBeaver is a multi-platform tool that supports numerous databases. Now, you can run any SQL query on the database. Installing the binary is straightforward, but unfortunately you need to be an administrator Configuring PowerBI The Python Database API (DBAPI) Installation pip install trino Quick Start Use the DBAPI interface to query Trino: if host is a valid url, the port and http schema will be automatically determined. In DBeaver, create a new connection and select SQLite as DB type. Install Process Extension installation in CE version: Main menu Help -> Install New Software Paste extension P2 repository URL into Work with field and press Enter Check items you wish to install Click Next->Finish. I download the ODBC driver using the latest version 0.3.3, you need to check always the latest release and make sure it is the right file. You can install optional extensions (plugins) in DBeaver. The ODBC driver is getting more stable, I thought it is an opportunity to test it with PowerBI, notice JDBC was always supported and can be used with SQL frontend like DBeaver and obviously Python and R has a native integration ![]() DuckDB is one of the most promising OLAP Engine in the market, it is open Source, very lightweight, and has virtually no dependencies and work in-Process (think the good Old MS Access ) and it is extremely fast, specially in reading and querying parquet files.
