Charlie Marsh	8f38b7a725	multiple: Remove unnecessary Ruff suppression comments (#21050) ... ## Summary I ran `ruff check --extend-select RUF100 -n` to identify `# noqa` comments that weren't having any effect in Ruff, and then `ruff check --extend-select RUF100 -n --fix` on select files to remove all of the unnecessary `# noqa: F401` violations. It's possible that these were needed at some point in the past, but they're not necessary in Ruff v0.1.15 (used by LangChain) or in the latest release.

Patrick McFadin	3331865f6b	community[minor]: add Cassandra Database Toolkit (#20246) ... **Description**: ToolKit and Tools for accessing data in a Cassandra Database primarily for Agent integration. Initially, this includes the following tools: - `cassandra_db_schema` Gathers all schema information for the connected database or a specific schema. Critical for the agent when determining actions. - `cassandra_db_select_table_data` Selects data from a specific keyspace and table. The agent can pass paramaters for a predicate and limits on the number of returned records. - `cassandra_db_query` Expiriemental alternative to `cassandra_db_select_table_data` which takes a query string completely formed by the agent instead of parameters. May be removed in future versions. Includes unit test and two notebooks to demonstrate usage. **Dependencies**: cassio **Twitter handle**: @PatrickMcFadin --------- Co-authored-by: Phil Miesle <phil.miesle@datastax.com> Co-authored-by: Bagatur <22008038+baskaryan@users.noreply.github.com> Co-authored-by: Bagatur <baskaryan@gmail.com>	5 months ago
