When there were 300 million data in the table, purge_table() worked normally, but when it increased to 450 million, the following error occurred.
I would like to hear the solution when the following error message occurs.
org.springframework.dao.RecoverableDataAccessException: ### Error querying database. Cause: java.sql.SQLRecoverableException: [Vertica][VJDBC](100024) IOException while communicating with server: java.io.EOFException. ### The error may exist in class path resource [mybatis/mapper/ros/ROSManageMapper.xml] ### The error may involve defaultParameterMap ### The error occurred while setting parameters ### SQL: SELECT public.purge_table(?) ### Cause: java.sql.SQLRecoverableException: [Vertica][VJDBC](100024) IOException while communicating with server: java.io.EOFException. ; [Vertica][VJDBC](100024) IOException while communicating with server: java.io.EOFException.; nested exception is java.sql.SQLRecoverableException: [Vertica][VJDBC](100024) IOException while communicating with server: java.io.EOFException. ### Error querying database.
