Should be less than 32 Review Comment: Can you provide an explanation as to why there is a limit? Also, I see below that you strip out the `-` characters, which would result in a 32 char string, so why further reduce it to 20 chars which compromises the uniqueness guarantees? ########## snowflake/src/main/java/org/apache/iceberg/snowflake/SnowflakeCatalog.java: ########## @@ -48,8 +51,12 @@ public class SnowflakeCatalog extends BaseMetastoreCatalog // Specifies the name of a Snowflake's partner application to connect through JDBC. // https://docs.snowflake.com/en/user-guide/jdbc-parameters.html#application private static final String JDBC_APPLICATION_PROPERTY = "application"; + // Add a suffix to user agent header for the web requests made by the jdbc driver. + private static final String JDBC_USER_AGENT_SUFFIX_PROPERTY = "user_agent_suffix"; Review Comment: Can you document that this is a property specifically used by the snowflake jdbc driver?

For example: ```scala > IcebergBuild.fullVersion() + IcebergBuild.gitCommitShortId() res1: String = Apache Iceberg 1.2.1 (commit 4e2cdccd7453603af42a090fc5530f2bd20cf1be)4e2cdcc ``` `IcebergBuild.fullVersion()` already includes the commit id, so you probably don't need the short version. -- This is an automated message from the Apache Git Service.
