In memory database open source5/3/2023 The concurrency control of non-replicated regions and client cache is similar to the way in replicated regions. When the update message has the same version stamp as the local cache, the one with the higher member ID will be kept. If the former one is larger, the member/client will perform the update and update the version stamp information. When an update message is received, the Geode member/client will compare the version stamp of the update message to the one in the local cache. If you need a high degree of data organization with a whole lot of descriptive data, t. The version stamp will get incremented each time an update for that entry appears. Answer (1 of 2): Why do you need that many columns Note that relational databases would require that you create a table with all those columns and that they be known in advance - or altered with ALTER TABLE. The consistency is retained by storing the version stamp and the Geode member ID which last updated the entry in each entry of a region. For a partitioned region, all the updates on a specific key will be routed to the primary Geode member serializable.įor a replicated region, as long as a member hosts the region, it can update the key and propagate it to other members.
