Kevin Si created BEAM-4261: ------------------------------ Summary: CloudBigtableIO should not try to validate runtime parameters at construction time. Key: BEAM-4261 URL: https://issues.apache.org/jira/browse/BEAM-4261 Project: Beam Issue Type: Bug Components: io-java-gcp Reporter: Kevin Si Assignee: Chamikara Jayalath
The workaround for user is to have some default values set and override them at runtime. One example of validating runtime parameter at construction time is following, and there are could be more. @Override public void validate() { ValueProvider<String> tableId = config.getTableId(); checkArgument(tableId != null && tableId.isAccessible() && !tableId.get().isEmpty(), "tableId was not supplied"); } A reported issue on stackoverflow: [https://stackoverflow.com/questions/49595921/valueprovider-type-parameters-not-getting-honored-at-the-template-execution-time] One concern I have is that if we disable the validation at construction time, how do we validate it at runtime? Ideally, users should use template parameter metadata for validation, but that is optional. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
