Anoop Sam John commented on HBASE-11696:
----------------------------------------
Yes [~stack] I got it like META blocks u r referring.
{code}
/**
* @param value true if we should cache data blocks in the L1 cache (if block
cache deploy
* has more than one tier; e.g. we are using CombinedBlockCache).
* @return this (for chained invocation)
*/
public HColumnDescriptor setCacheDataInL1(boolean value) {
return setValue(CACHE_DATA_IN_L1, Boolean.toString(value));
}
{code}
The above javadoc confused me. I thought the data blocks for that HCD will be
stored in L1.
> Make CombinedBlockCache resizable.

> HBASE-5349 adds auto tuning of memstore heap and block cache heap. Block
> cache needs to be resizable in order for this. CombinedBlockCache is not
> marked resizable now. We can make this. On resize the L1 cache (ie. LRU
> cache) can get resized.
