Hello, Ignite can be thought as any other db where sequence of write doesn't guarantee sequence of read. In case of querying data via sql, you can make sure data is returned in sequence by using order by query of particular column.
In Ignite cache, data is stored across partition and which record is stored on which partition depends on somekind of hash of the key.
