Subject [jira] [Commented] (AURORA-1833) Expose stats on MyBatis mapped statements
Date Sun, 27 Nov 2016 18:59:58 GMT

    [ https://issues.apache.org/jira/browse/AURORA-1833?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15700150#comment-15700150

Reza Motamedi commented on AURORA-1833:
---------------------------------------

MyBatis allows us to intercept calls within the execution of a mapped statement. This allows
us to time various mapped statements and ultimately gain more insight on the performance of
the database module.

> Aurora exposes stats on high level storage operations. However, stats on individual low
level MyBatis mapped statements is not currently exposed. Intercepting and exposing timing
stats on these statements can facilitate database level optimizations such identifying long
running queries, missing indexes, batching, etc.
> Please note that query stats can also be acquired from H2 through {{INFORMATION_SCHEMA.QUERY_STATISTICS}}
meta-table.
