By implementing Flight SQL, a database can support clients that use ADBC, JDBC, and ODBC. ADBC is an API specification oriented at database clients. By coding to ADBC, an application can get Arrow data from a variety of databases that use different client technologies underneath.
May 9, 2023 · As you can see, ADBC performs over 33% faster than a very optimized JDBC setup, and over 21x faster than the default JDBC configuration! Further, the Python code complexity is much less for ADBC and works out of the box with minimal setup.
Oct 3, 2024 · ADBC avoids the row-to-column conversion by working directly with Arrow’s columnar format. This means faster data transfer and minimal overhead, notably as datasets get larger. Benchmarks have...
May 13, 2024 · Correspondingly, we need faster and faster data reading and transmission, so we start to look for better answers than JDBC and ODBC. Thus, we include Arrow Flight SQL protocol into Apache Doris 2.1, which provides tens-fold speedups for data transfer.

- Towards An Arrow-Native Future For Database Clients and Vendors
Why two projects? Because database clients and vendors face overlapping but distinct problems. Database clients face a choice when deciding how to get Arrow data. They could start from a tried-and-true, generic API like JDBC and ODBC. This choice makes it easy to work with different databases. But, neither API has native support for the Arrow colum...
Database vendors can use Flight SQL to build on top of the Arrow Flight stack. Flight RPC provides a framework for transporting Arrow data. Flight SQL tells us how to use Flight RPC—what messages to send, what calls to make—for talking to databases that implement the Flight SQL protocol. Just like how projects like Google Cloud Spanner and Amazon A...
Currently, database clients who want to access Arrow data have two options. Unfortunately, each option has a downside.
To summarize: 1. Flight RPCis a framework for fast network transport of Arrow data. But, it lacks semantics, and assumes that database vendors will bring their own semantics. 2. Flight SQLis a client driver and a wire protocol. It helps database vendors by defining the semantics for interacting with databases using Flight RPC—executing queries, fet...
Jul 16, 2012 · There is no any relationship in terms of performance between JNDI and JDBC, because JNDI returns some properties that helps application developer or application server to get database connection using JDBC; low level API for database connectivity. A database connection always uses JDBC.
Jun 15, 2015 · Creating a REST API and having your web app use the REST API to do all interactions with your database OR querying your database directly (i.e. using whatever typical object your language uses to query a database such as JDBC for Java)?
