The row header is split into five sections:

• Begin Ts: This is the timestamp of the transaction that inserted the row into the database.
• End Ts: This is the timestamp of the transaction that deleted the row from the database. For rows that have not yet been deleted, this field contains a value infinity.
• StmtId: This field stores a unique statement ID corresponding to the statement inside the transaction that created this row.
• IdxLinkCount: This field is a counter for the number of indexes that reference this row. An In-Memory table stores data only and has no reference to other rows in the table. The indexes that are linked to the table control which rows belong together.
• Finally, we have a set of pointers that reference the indexes connected to this row. The number of pointers stored here corresponds directly to the number of indexes that reference this row.
