isAtomicUpdate
public static boolean isAtomicUpdate(AddUpdateCommand cmd)
Utility method that examines the SolrInputDocument in an AddUpdateCommand and returns true if the documents contains atomic update instructions.

merge
public SolrInputDocument merge(SolrInputDocument fromDoc, SolrInputDocument toDoc)
Merges the fromDoc into the toDoc using the atomic update syntax.- Parameters:
fromDoc
- SolrInputDocument which will merged into the toDoctoDoc
- the final SolrInputDocument that will be mutated with the values from the fromDoc atomic commands- Returns:
- toDoc with mutated values
-
computeInPlaceUpdatableFields
public static Set<String> computeInPlaceUpdatableFields(AddUpdateCommand cmd) throws IOException
Given an add update command, compute a list of fields that can be updated in-place. If there is even a single field in the update that cannot be updated in-place, the entire update cannot be executed in-place (and empty set will be returned in that case).- Returns:
- Return a set of fields that can be in-place updated.
- Throws:
IOException
-
doInPlaceUpdateMerge
public boolean doInPlaceUpdateMerge(AddUpdateCommand cmd, Set<String> updatedFields) throws IOException
Given an AddUpdateCommand containing update operations (e.g. set, inc), merge and resolve the operations into a partial document that can be used for indexing the in-place updates. The AddUpdateCommand is modified to contain the partial document (instead of the original document which contained the update operations) and also the prevVersion that this in-place update depends on. Note: updatedFields passed into the method can be changed, i.e. the version field can be added to the set.- Returns:
- If in-place update cannot succeed, e.g. if the old document is deleted recently, then false is returned. A false return indicates that this update can be re-tried as a full atomic update. Returns true if the in-place update succeeds.
- Throws:
IOException
