I have simple SELECT QUERY which takes more than 3 seconds to get the result. Actual result count is 15211
Query:
select meta().id assetId, modelAndPart.partNumberID,assetLocation.id locationId from ic_v10_mammoet where type = 'asset' and modelAndPart IS NOT null and tenantId='439'

Answer 1

Yes, you forgot to ask a question. You can use this index.
CREATE INDEX idx_assets ON somedata
( tenantId, modelAndPart.partNumberID, assetLocation.id )
WHERE type = 'asset';
