Ivan Bessonov updated IGNITE-22667:
-----------------------------------
Description:
We should write comparator for RocksDB in C++, contact [~ibessonov] for
references
Examples of native comparators for RocksDB can be found here:
[https://github.com/facebook/rocksdb/blob/2e09a54c4fb82e88bcaa3e7cfa8ccbbbbf3635d5/java/src/test/java/org/rocksdb/NativeComparatorWrapperTest.java]
[https://github.com/facebook/rocksdb/blob/06c8afeff5b9fd38a79bdd4ba1bbb9df572c8096/java/rocksjni/native_comparator_wrapper_test.cc]
Only applicable for sorted indexes, because they use complicated algorithm for
comparing binary tuples. Schema of these tuples is encoded in CF name, so
reading it is not an issue.
