15 : * @* BAT Buffer Pool (BBP)
16 : * The BATs created and loaded are collected in a BAT buffer pool.
17 : * The Bat Buffer Pool has a number of functions:
18 : * @table @code
19 : *
20 : * @item administration and lookup
21 : * The BBP is a directory which contains status information about all
22 : * known BATs. This interface may be used very heavily, by
23 : * data-intensive applications. To eliminate all overhead, read-only
24 : * access to the BBP may be done by table-lookups. The integer index
25 : * type for these lookups is @emph{bat}, as retrieved by
26 : * @emph{b->batCacheid}. The @emph{bat} zero is reserved for the nil
27 : * bat.
28 : *
29 : * @item persistence
30 : * The BBP is made persistent by saving it to the dictionary file
31 : * called @emph{BBP.dir} in the database.
32 : *
33 : * When the number of BATs rises, having all files in one directory
34 : * becomes a bottleneck. The BBP therefore implements a scheme that
35 : * distributes all BATs in a growing directory tree with at most 64
36 : * BATs stored in one node.
37 : *
38 : * @item buffer management
39 : * The BBP is responsible for loading and saving of BATs to disk. It
40 : * also contains routines to unload BATs from memory when memory
41 : * resources get scarce. For this purpose, it administers BAT memory
42 : * reference counts (to know which BATs can be unloaded) and BAT usage
43 : * statistics (it unloads the least recently used BATs).
44 : *
45 : * @item recovery
46 : * When the database is closed or during a run-time syncpoint, the
47 : * system tables must be written to disk in a safe way, that is immune
48 : * for system failures (like disk full). To do so, the BBP implements
49 : * an atomic commit and recovery protocol: first all files to be
50 : * overwritten are moved to a BACKUP/ dir. If that succeeds, the
51 : * writes are done. If that also fully succeeds the BACKUP/ dir is
52 : * renamed to DELETE_ME/ and subsequently deleted. If not, all files
53 : * in BACKUP/ are moved back to their original location.
54 : *
55 : * @item unloading
56 : * Bats which have a logical reference (ie. a lrefs > 0) but no memory
57 : * reference (refcnt == 0) can be unloaded. Unloading dirty bats
58 : * means, moving the original (committed version) to the BACKUP/ dir
59 : * and saving the bat. This complicates the commit and recovery/abort
60 : * issues. The commit has to check if the bat is already moved. And
61 : * The recovery has to always move back the files from the BACKUP/
62 : * dir.
63 : *
64 : * @item reference counting
65 : * Bats use have two kinds of references: logical and physical
66 : * (pointer) ones. The logical references are administered by
67 : * BBPretain/BBPrelease, the physical ones by BBPfix/BBPunfix.

188 : * @+ BBP Consistency and Concurrency
189 : * While GDK provides the basic building blocks for an ACID system, in
190 : * itself it is not such a system, as we this would entail too much
191 : * overhead that is often not needed. Hence, some consistency control
192 : * is left to the user. The first important user constraint is that if
193 : * a user updates a BAT, (s)he himself must assure that no-one else
194 : * accesses this BAT.
195 : *
196 : * Concerning buffer management, the BBP carries out a swapping
197 : * policy. BATs are kept in memory till the memory is full. If the
198 : * memory is full, the malloc functions initiate BBP trim actions,
199 : * that unload the coldest BATs that have a zero reference count. The
200 : * second important user constraint is therefore that a user may only
201 : * manipulate live BAT data in memory if it is sure that there is at
202 : * least one reference count to that BAT.
203 : *
204 : * The main BBP array is protected by two locks:
205 : * @table @code
206 : * @item GDKcacheLock]
207 : * this lock guards the free slot management in the BBP array. The
208 : * BBP operations that allocate a new slot for a new BAT
209 : * (@emph{BBPinit},@emph{BBPcacheit}), delete the slot of a destroyed
210 : * BAT (@emph{BBPreclaim}), or rename a BAT (@emph{BBPrename}), hold
211 : * this lock. It also protects all BAT (re)naming actions include
212 : * (read and write) in the hash table with BAT names.
213 : * @item GDKswapLock
214 : * this lock guards the swap (loaded/unloaded) status of the
215 : * BATs. Hence, all BBP routines that influence the swapping policy,
216 : * or actually carry out the swapping policy itself, acquire this lock
217 : * (e.g. @emph{BBPfix},@emph{BBPunfix}). Note that this also means
218 : * that updates to the BBP_status indicator array must be protected by
219 : * GDKswapLock.
220 : *
221 : * To reduce contention GDKswapLock was split into multiple locks; it
222 : * is now an array of lock pointers which is accessed by
223 : * GDKswapLock(bat)
224 : * @end table
225 : *
226 : * Routines that need both locks should first acquire the locks in the
227 : * GDKswapLock array (in ascending order) and then GDKcacheLock (and
228 : * release them in reverse order).
229 : *
230 : * To obtain maximum speed, read operations to existing elements in
231 : * the BBP are unguarded. As said, it is the users responsibility that
232 : * the BAT that is being read is not being modified. BBP update
233 : * actions that modify the BBP data structure itself are locked by the
234 : * BBP functions themselves. Hence, multiple concurrent BBP read
235 : * operations may be ongoing while at the same time at most one BBP
236 : * write operation @strong{on a different BAT} is executing. This
237 : * holds for accesses to the public (quasi-) arrays @emph{BBPcache},
238 : * @emph{BBPstatus} and @emph{BBPrefs}.
239 : * These arrays are called quasi as now they are
240 : * actually stored together in one big BBPrec array called BBP, that
241 : * is allocated in anonymous VM space, so we can reallocate this
242 : * structure without changing the base address (a crucial feature if
243 : * read actions are to go on unlocked while other entries in the BBP
244 : * may be modified).
