# Which Problems Are Solved The mirror command used the wrong position to filter for events if different database technologies for source and destination were used. # How the Problems Are Solved The statements which diverge are stored on the client so that different technologies can use different statements. # Additional Context - https://discord.com/channels/927474939156643850/1256396896243552347
