Lower memory usage in FragmentRepository
Avoid using Spring Data "interface projection" in FragmentRepository.
The use of FragmentExtract in FragmentRepository is causing an
overhead of around 5 kilobytes per fragment, which is leading to
abnormally high memory usage when queries return a large number of
nodes. For example, around 250MB of additional memory is needlessly
used when fetching 50,000 datanodes.
- Remove FragmentExtract interface and FragmentEntityArranger class.
- Add FragmentPrefetchRepository, using JdbcTemplate and RowMapper
to fetch FragmentEntity descendants in a single SQL query.
- Many CpsDataService operations have memory reductions:
- queryDataNodes
- getDataNodesForMultipleXpaths
- updateDataNodesAndDescendants
- updateNodeLeaves
- and any NCMP methods using the above.
