Thus, they implement a generalized version of a Btree, where +the key and data can be arbitrary length. + +Internally, a row store and column store both use a common \c WT_BTREE +structure. The fundamental difference is that +<code>WT_BTREE->type == BTREE_ROW</code> for row stores. +Internal functions that navigate, access and manipulate Btrees have +code sprinkled throughout that is conditional on <code>WT_BTREE->type</code>. +*/ |
