Detailed Description

Identifiers for persistent storage entities are used throughout the storage manager API. This page collects them for convenience of reference.

The following persistent storage structures have identifiers, not all of which(ids) are persistent:

• Indexes: stid_t (store id)
• Files: stid_t (store id)
• Records: rid_t (record id)
• Pages: pid_t (short page id), lpid_t (long page id)
• Volumes: vid_t (short volume id), lvid_t (long volume id)
• Device

Typedef Documentation

typedef uint4_t snum_t

Store Number.

This type represents a store number, used when the volume id is implied somehow.

See Identifiers.

Definition at line 49 of file stid_t.h.

typedef w_base_t::uint4_t extnum_t

Extent Number.

This type represents an extent number, used in extid_t.
