How tstats is working when some data model acceleration summaries in indexer cluster is missing

Path Finder


by default, DMA summaries are not replicated between nodes in indexer cluster (for warm and cold buckets). I wonder how command tstats with summariesonly=true behaves in case of failing one node in cluster.

Imagine, I have 3-nodes, single-site IDX cluster in deafult setting. What happened, when one node fails (so summaries on that node are not available) and I run search using "|tstats summariesonly=true..." on this cluster?

If search spans data from primary warm or cold buckets on failed node, will I get incomplete data, right? (I think so, because appropriate summaries are missing). And if so, will I get any error message on search page?

And how it change in case of multi-site cluster? I assume in case of failing one node, I should get complete data, becuase AFAIK in multi-site cluster every site has primary copy of bucket with DMA summaries. Is it right or not?

I need this info because of one project I am working on. Thank you for answers.

Best regards
