2 items for all items (except mod-data-import)

2 partition for all DI kafka topics:

Examples:

delete old topic
# ./kafka-topics.sh --bootstrap-server=<kafka-ip>:9092 --delete --topic perf-eks-folijet.Default.fs09000000.DI_ERROR

recreate topic with "--partitions 2 --replication-factor 1"
# ./kafka-topics.sh --bootstrap-server=<kafka-ip>:9092 --create --topic perf-eks-folijet.Default.fs09000000.DI_ERROR --partitions 2 --replication-factor 1
WARNING: Due to limitations in metric names, topics with a period ('.') or underscore ('_') could collide. To avoid issues it is best to use either, but not both.
Created topic perf-eks-folijet.Default.fs09000000.DI_ERROR.

Performance testing of update item scenario after removal of index (MODDATAIMP-697):

In the scope of FOLIO-3388 "item_status_name_idx_gin" index for the Item status field was removed from mod-inventory-storage. However, the this index potentially can be used for matching by Item status during Item update.

jobprofile structure

Test results:

Example of the CQL query built during while processing the sub-match profile for matching by status: 

...

SELECT id, jsonb, creation_date, created_by, holdingsrecordid, permanentloantypeid, temporaryloantypeid, materialtypeid, permanentlocationid, temporarylocationid, effectivelocationid
FROM fs09000000_mod_inventory_storage.item
WHERE (
	CASE WHEN length(lower(f_unaccent('Missing'))) <= 600 
		 THEN left(lower(f_unaccent(item.jsonb->'status'->>'name')),600) LIKE lower(f_unaccent('Missing')) 
		 ELSE left(lower(f_unaccent(item.jsonb->'status'->>'name')),600) LIKE left(lower(f_unaccent('Missing')),600) AND lower(f_unaccent(item.jsonb->'status'->>'name')) LIKE lower(f_unaccent('Missing')) 
	END
