------------------------------------------
Summary: Write to write-compatible indices when writing to
partition
Key: IGNITE-20125
URL: https://issues.apache.org/jira/browse/IGNITE-20125
Project: Ignite
Issue Type: Improvement
Reporter: Roman Puchkovskiy
Fix For: 3.0.0-beta2
For each operation that is writing, the operation’s timestamp (which moves
partition’s SafeTime forward) T~op~ is used to get the schema corresponding to
the operation. When it’s obtained, all writable (STARTING, READY, STOPPING)
indices that are write-compatible at T~op~ are taken, and the current operation
writes to them all.
An index is write-compatible at timestamp T~op~ if for each column of the index
the following holds: the column was not dropped at all, or it was dropped
strictly after T~op~.
If an index does not exist anymore at T~op~, the write to it is just ignored,
the transaction is not aborted.
