See also #30404 `PrimaryKey` is used to hold pk values for both int64 & varchar data type. Since it is an interface it may occupies more memory than pure slices when holding a group of pks. This PR add `PrimaryKeys` interface when some other module need to hold lots of PrimaryKeys. By using this interface, it could reduce the memory of pk slice to half when using Int64 Pk data type and reduce interface cost for each row of varchar as well. --------- Signed-off-by: Congqi Xia <congqi.xia@zilliz.com>
