In the index/store package introduce KVReader creates snapshot all read operations consistent from this snapshot must close to release introduce KVWriter only one writer active access to all operations allows for consisten read-modify-write must close to release introduce AssociativeMerge operation on batch allows efficient read-modify-write for associative operations used to consolidate updates to the term summary rows saves 1 set and 1 get op per shared instance of term in field In the index package introduced an IndexReader exposes a consisten snapshot of the index for searching At top level All searches now operate on a consisten snapshot of the index
