Re: Interesting heap dump of an OOME running Performance Evaluation on trunk

Wed, 26 Mar 2008 12:16:43 -0700

Each region has a memcache. Memcache is 64MB. Each HStoreKey has two Texts -- one for row, other for column. 30*(64MB/1k records) each of which has a HSK makes for almost 4M keys. With half-full memcaches, we can easily have 1.3M keys if my math is right.
Regards the other objects, 30 regions * 2-10 store files -- up to 10 store files if region is being overrun with updates -- with some logging thrown in is only about 100odd so maybe something going on here. But do these items have any weight? Are they large? (If buffers were 4k.. then we're talking about 1M for 227 instances?)

Yikes. 1.3M Texts for 30 regions? that's crazy. Seems like we must be 
doing something wrong there.

Ok, so no big surprise that there are a lot of Text and HStoreKeys lying
around, but look at the other stuff hanging out that really should not
be, esp when you consider the number of HRegions
