Bug #4832
Updated by Nicolas CHARLES over 10 years ago
Since #4831, type of reports have changed from integer to bigint. We will not migrate table automatically: it can take a very long time to perform and therefore could not fit in an automatic migration script. We will provide a script available in /opt/rudder/... that will make the migration whenever the user is ok to run it. In the migration process we will check if there is a still a table that needs migration and warn the user that there is something he can do! there is 3 tables to look at : ruddersysevents (id), archivedruddersysevents (id), and statusUpdated (lastId) The process to update reports table is more complicated: * Ask if the user wish to keep all the previous reports or not ** if not keeping the previous reports, ask confirmation * In a transaction: ** Rename table to old_table ** drop all indexes except the index on nodes ** create new "table" with bigint as id * Outside the transaction: * create new indexes on the new table * If the user wish to keep all reports ** copy everything * If the user does not wish to keep all reports ** copy latest 1000 reports of each node in the table *** the copy is node by node, with display of the amout of node copied, and reports are dropped each time a copy is made ** * Drop "old_table"
