Mirza Aliev updated IGNITE-18955:
---------------------------------
Description:
{*}Motivation{*}:
We need to be able to use filters when data nodes are recalculated
*Definition of done:*
* Filters are applied when data nodes are recalculated
*Implementation details:*
After the parsing phase, the expression can be converted to a condition for the
filter from the Java Stream API. This filtering can be performed on a set of
nodes’ attributes. This set could be retrieved from the CMG, we just need
consistentIds of nodes.
After that we need to use this filter when we write data nodes to metastore,
there are few places, where we do that
* {{DistributionZoneManager#saveDataNodesToMetaStorageOnScaleUp}}
* {{DistributionZoneManager#saveDataNodesToMetaStorageOnScaleDown}}
* {{DistributionZoneManager#saveDataNodesAndUpdateTriggerKeysInMetaStorage}}
