Subject [jira] [Commented] (IGNITE-1835) .Net: Use thread-local pool to store schemas in PortableWriter
Date Tue, 03 Nov 2015 12:47:27 GMT

    [ https://issues.apache.org/jira/browse/IGNITE-1835?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14987203#comment-14987203

Pavel  Tupitsyn commented on IGNITE-1835:
-----------------------------------------

I'm not sure about shrinking. If the array has come to a certain size, it happened for a reason,
and it will probably happen again. Doing 2 reallocations of an array on each write will perform
poorly. 

And we are talking about laughable savings here. In Java there is a 256*4=1KB limit for the
buffer.
