ScyllaDB is a high-performance, distributed NoSQL database designed to handle large volumes of data with low latency. It is compatible with Apache Cassandra and offers enhanced performance and scalability. ScyllaDB is widely used for applications that require high throughput and low latency, such as real-time analytics, IoT, and time-series data.
When attempting to create a table in ScyllaDB, you might encounter a failure with an error message. This error typically indicates issues with the schema or resource constraints that prevent the table from being created successfully.
Some common error messages you might see include:
The TableCreationFailure issue arises when ScyllaDB cannot create a table due to problems in the schema or lack of resources. This can occur if the schema contains syntax errors, unsupported data types, or if the system lacks the necessary memory or disk space to accommodate the new table.
Schema errors can include:
Resource constraints may involve:
To resolve the TableCreationFailure issue, follow these steps:
Ensure that your schema is correctly defined. Check for syntax errors and verify that all necessary keys are included. Use the following command to validate your schema:
DESCRIBE TABLE your_keyspace.your_table;
Refer to the ScyllaDB DDL Documentation for more information on schema definitions.
Verify that your system has enough resources to create the table. Check memory and disk usage with:
free -h
# Check disk space
df -h
Ensure that there is sufficient free memory and disk space. Consider scaling your cluster if resources are consistently low.
After validating the schema and ensuring adequate resources, retry creating the table:
CREATE TABLE your_keyspace.your_table (
id UUID PRIMARY KEY,
name text,
value int
);
By following these steps, you can diagnose and resolve the TableCreationFailure issue in ScyllaDB. Ensuring a correct schema and adequate resources are key to successful table creation. For further assistance, consult the ScyllaDB Documentation or reach out to the ScyllaDB Support Team.
