Aleksandr Polovtcev updated IGNITE-14928:
-----------------------------------------
Description:
The index storage requires the following new entities:
# {{IndexKey}} - to serve as a key in the index storage and as a search
parameter in queries. It should be serializable into a byte array, but not
necessarily deserializable. Some of the columns included in the key can be
omitted for range queries support.
# {{IndexValue}} - to serve as a value in the index storage and as a result
from the queries.
# {{IndexSchema}} - to serve as a descriptor for (de-)serializing IndexKeys and
IndexValues.
The whole concept is similar to the {{BinaryRow}} but requires a different
serialization protocol (e.g. no schema version and no key/value separation),
but it should be possible to reuse some classes from the {{ignite-schema}}
module.
