Kirill Tkalenko updated IGNITE-20863:
-------------------------------------
Description:
To implement IGNITE-20125, we need to correctly select the indexes into which
we will insert data during RW transactions update operations for partitions.
It is enough for us to collect all available and registered indexes at the time
of the operation, as well as all dropped available indexes that we can know
about.

To implement IGNITE-20125, we need to correctly select the indexes into which
we will insert data during RW transactions 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.
