----------------------------------------
Summary: Selecting indexes when performing update operations for
partition
Key: IGNITE-20863
URL: https://issues.apache.org/jira/browse/IGNITE-20863
Project: Ignite
Issue Type: Improvement
Reporter: Kirill Tkalenko
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.
