The problem, however, is that there is minimal cost and overhead associated with not only tearing down existing connections, file-handles, and buffer allocations in order to ‘shut down’ a database when it auto-closes, but there can also be significant overhead involved in spinning a database back up when it’s accessed by subsequent applications or users.

Partitioning is a solution for storage problems, ie. Determine on what filegroup data is located based on some field value. On its own, it gives no .
SQL Server 2008 added a few bits; it struck me that if you need to use a wizard to turn an existing table into a partitioned table then your not really planning ahead. To be fair, straight out of the box there is no tooling surrounding partitioning either except for a handful of DMV’s – if you want to automate a rolling window, then you need to program that yourself.

So, only in the most theoretical and perfectly considered environment would AutoClose even begin to make sense on a production database – meaning that you really don’t want to go there. 99% of production databases out there, this shouldn’t even be a consideration. Similarly, I think it could be (theoretically) argued that in some very rare and very well-thought-out edge cases that turning on AutoClose on a production server/database might make sense. 01% of databases where this might even make sense to consider, I’m guessing that in 99% of those cases, AutoClose will STILL be the wrong choice.

If I am going to auto-balance the partitions then I have to know what objects are using the partition schema and will be affected by any balancing – we can not assume it is a single object, since we know both the table and non-clustered indexes will often be aligned on the same partition schema, as could other tables / objects.
A logical clock is used to identify (in relative terms) when a change is made on the primary – for those who know something of the MySQL Cluster internals, we use the index of the Global Checkpoint that the update is contained in. For all tables that have this feature turned on, an extra, hidden column is automatically added on the primary – this represents the value of the logical clock when the change was made.
Running this gave 40 rows, 4 objects x 10 partitions, so I was filtered down to the partitioned objects but I returned too many rows – I could have used a group by clause but it seemed simpler to just select a single partition number, and since I know partition number 1 will always exist, that was the simplest to use.
Finally, when rows are deleted from a table, the memory for those rows would typically remain allocated against that table and so it is helpful to understand how many of these ‘empty slots’ are available for use by new rows in that table. 4 introduces a new table – ndbinfo. MySQL Cluster allocates all of the required memory when a data node starts and so any information on memory usage from the operating system is of limited use and provides no clues as to how memory is used with the data nodes – for example, which tables are using the most memory. Memory_per_fragment – that provides that information. Also, as this is a distributed database, it is helpful to understand whether a particular table is using a similar amount of memory in each data node (if not then it could be that a better partitioning/sharding key could be used).
