Change Category: Operability
Complexity: Normal
Status: Open (was: Triage Needed)
> Add support of vector type to COPY command
> ------------------------------------------
>
> Key: CASSANDRA-19118
> URL: https://issues.apache.org/jira/browse/CASSANDRA-19118
> Project: Cassandra
> Issue Type: Improvement
> Components: CQL/Interpreter
> Reporter: Szymon Miezal
> Assignee: Szymon Miezal
> Priority: Normal
>
> Currently it's not possible to import rows with vector literals via {{COPY}}
> command.
> STR:
> * Create a table
> {code:sql}
> CREATE TABLE testcopyfrom (id text PRIMARY KEY, embedding_vector
> VECTOR<FLOAT, 6>
> {code}
> * Prepare csv file with sample data, for instance:
> {code:sql}
> 1,"[0.1, 0.2, 0.3, 0.4, 0.5, 0.6]"
> 2,"[-0.1, -0.2, -0.3, -0.4, -0.5, -0.6]" {code}
> * in cqlsh run
> {code:sql}
> COPY ks.testcopyfrom FROM data.csv
> {code}
> It will result in getting:
> {code:sql}
> TypeError: Received an argument of invalid type for column
> "embedding_vector". Expected: <class 'cassandra.cqltypes.VectorType(6)'>,
> Got: <class 'str'>; (required argument is not a float){code}
