Title:
Still no interoperability betwen 64 bit indexes and 32 bit keys
Status in Tarantool - an efficient in-memory data store:
Fix Released
Bug description:
When I have a 64 bit index type, and using a 32 bit key for search, I
get an error.
This is pain in the butt especially since the driver is unaware of the
schema, and can't properly pack an integer without this knowledge.
For example, try to create a space with 64-bit primary key (TREE or HASH) and
search it
using a 32-bit key:
space[27].enabled: "true"
space[27].cardinality: "-1"
space[27].estimated_rows: "0"
space[27].index[0].type: "TREE"
space[27].index[0].unique: "true"
space[27].index[0].key_field[0].fieldno: "0"
space[27].index[0].key_field[0].type: "NUM64"
space[28].enabled: "true"
space[28].cardinality: "-1"
space[28].estimated_rows: "0"
space[28].index[0].type: "HASH"
space[28].index[0].unique: "true"
space[28].index[0].key_field[0].fieldno: "0"
space[28].index[0].key_field[0].type: "NUM64"
