{color:red}-1 lineLengths{color}. The patch introduces the following lines
longer than 100:
+ * <code>hbase(main):003:0> create 't', {NAME => 't', CONFIGURATION =>
{CACHE_DATA_IN_L1 => 'true'}}</code>
+ LruBlockCache, and BucketCache, and SlabCache, which are both
(usually) offheap. This section
+ two tiers and how blocks move between them is done by
<classname>DoubleBlockCache</classname>
+ <xref linkend="offheap.blockcache.slabcache" /> for more detail
on how DoubleBlockCache works.
+ It keeps all DATA blocks in the BucketCache and meta blocks --
INDEX and BLOOM blocks --
+ works so differently, it is difficult to do a fair comparison
between BucketCache and SlabCache.

+ DoubleBlockCache is an abstraction layer that combines two
caches, the smaller onHeapCache and the

> This is a prerequisite for HBASE-11323 BucketCache on all the time. It
> addresses a @lars hofhansl ask that we be able to ask that for some column
> families, even their data blocks get cached up in the LruBlockCache L1 tier
> in a multi-tier deploy as happens when doing BucketCache (CombinedBlockCache)
> setups.
