> Fix For: 3.0.0-beta2

>
> To implement IGNITE-20125, we need to correctly select the indexes into which
> we will insert data during update operations for partitions.
> What do we need for this:
> # Catalog version of the transaction by beginTs of the txId.
> # Catalog version of the update operation for the transaction.
> An approximate index selection algorithm:
> # Start with the catalog version at the beginning of the transaction.
> # Selecting all indexes by catalog version for a specific table.
> ## If the index is not in the resulting selection, then simply add it.
> ## If the index is already present in the resulting selection, then we do
> nothing.
> ## If the index is present in the resulting selection but not in the catalog
> version, then depending on its status it will be:
> ### registered - the index will be removed from the resulting selection.
> ### available - will remain in the resulting selection.
> # Increase the catalog version, if it is greater than the directory version
> for the update operation, then we will complete the index selection, else go
> to p. 2.
