-----------------------------------------
Summary: 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
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}
