Submitting queries with DataStax drivers

The ability to submit queries and receive results is the core functionality of DataStax drivers.

The DataStax drivers can query clusters with different workload types.

The DataStax drivers allow developers to perform DSE Search queries in their applications.

The DataStax drivers expose the String API and Fluent API for executing DSE Graph traversals.

Large result sets can be divided into multiple pages that the client will fetch in separate network requests.

Queries can be executed against the database synchronously or asynchronously.

The DataStax drivers support sending multiple concurrent requests on a single connection to improve overall query performance.

Speculative queries are used to preemptively start a second execution of a query against another node, before the first node has replied or returned an error.

A CQL query is idempotent if it can be applied multiple times without changing the result of the initial application.

DataStax drivers expose metrics through different libraries and APIs depending on the language.

The C#, Java, Node.js and Python drivers each provide an object mapper, which are tools for managing query results.

Timestamps determine the order of precedence for operations on the same column value from different queries.
