Hemanth Yamijala commented on ATLAS-793:
----------------------------------------
I have reviewed the patch attached to review board and raised some comments.
In addition, I tested the patch using the current UI to add & search for terms,
and a REST client to delete them. A few issues that I see:
* For every GET call made to the term name, I see the following printed in the
log:
{code}
Query requires iterating over all vertices [()]. For better performance, use
indexes (StandardTitanTx:1238)
{code}
I don't think this is introduced by the delete patch. Hence, will file a
separate JIRA for this.
* A couple of times, I saw this line:
{code}
Evicted [23@c0a8010822410-hemanthijalambp-home1] from cache but waiting too
long for transactions to close. Stale transaction alert on:
[standardtitantx[null], standardtitantx[null], standardtitantx[null],
standardtitantx[null], standardtitantx[null], standardtitantx[null],
standardtitantx[null], standardtitantx[null]] (ManagementLogger:189)
{code}
I did raise a comment on review board about issues with missing to close
transactions in Titan. I suspect this may be related to changes done in this
patch. I tried to replicate this by trying out specific scenarios -
unfortunately, I couldn't do that. I will upload the application.log to the
file in case it helps (although, it is too verbose to be useful, I suspect).
* Search for entities associated with a tag is using the same search pipeline
as v1 search for entities, and so may suffer from the same performance
limitations. Although in this case, I am not entirely sure if search via the v0
API i.e. ISA DSL search is any more optimized than this. Can try and resolve
this as part of ATLAS-807.
