BigTable est utilisé pour plusieurs raisons : + +- Toucher un large ensemble d'applications +- Mise à l'échelle +- Très bonnes performances (temps de réponse...) +- Forte disponibilité + +Le modèle de données de BigTable +-------------------------------- + +Le modèle de données de BigTable se comporte comme un dictionnaire +multidimensionnel (matrice) indexé par le triplet +<row key, column key, timestamp>. Chaque valeur de ce dictionnaire +est un table d'octets. + +Les clés pour une rangée du dictionnaire sont des chaînes de charactères +arbitraires et BigTable maintient les données dans un ordre lexicographique +grâce à ce type de clé. + +ex de clé de rangée : "com.google.maps/index.html" (reversed URL) + +La portée d'une rangée est appelée "tablet", unité de distribution et d'équilibrage +de charge. + +Les clés de colonne sont groupées en ensembles appelés "famille de colonnes". +Une clé de colonne est nommé suivant le schéma : family:qualifier. +Les noms de famille doivent être lisibles facilement mais les qualificateurs peuvent +être des chaînes de charactères arbitraires + +ex de famille de colonne : "contents:" + +Ainsi, le contenu d'une cellule indexée par <com.google.maps/index.html, contents:, ?> +serait le contenu de la page "index.html" (le code html). +Une cellule peut contenir plusieurs versions de la même donnée via le mécanisme de timestamp. +Chaque cellule stocke plusieurs timestamp en ordre décroissant si bien que : + +- <com.google.maps/index.html, contents:, ts1> donne la version la plus récente du contenu. +- <com.google.maps/index.html, contents:, ts2> donne une version plus ancienne du contenu. + +Stockage +-------- + +BigTable utilise le système de fichier google GFS (Google File System) +pour stocker les logs et fichiers de données. + +Le format de fichier google SSTable est utilisé pour stocker les données +internes à BigTable. + +API BigTable (client) +--------------------- + +Voici les fonctionnalités prévues par la spécification BigTable : + +- Création de tables. +- Création de familles de colonne. +- Suppression de tables. +- Suppression de familles de colonne. +- Changement de cluster (?). +- Changement de table. +- Changement de méta données sur une famille de colonne (droits d'accès...). +- Ecriture des données dans une table. +- Suppression des données dans une table. +- Recherche des données dans une table depuis des rangées individuelles. +- Itération sur un sous-ensemble de données d'une table. +- Manipulation avancée des données : Transactions "Lecture -

Additional Definitions. + + As used herein, "this License" refers to version 3 of the GNU Lesser +General Public License, and the "GNU GPL" refers to version 3 of the GNU +General Public License. + + "The Library" refers to a covered work governed by this License, +other than an Application or a Combined Work as defined below. + + An "Application" is any work that makes use of an interface provided +by the Library, but which is not otherwise based on the Library. +Defining a subclass of a class defined by the Library is deemed a mode +of using an interface provided by the Library. + + A "Combined Work" is a work produced by combining or linking an +Application with the Library. The particular version of the Library +with which the Combined Work was made is also called the "Linked +Version". + + The "Minimal Corresponding Source" for a Combined Work means the +Corresponding Source for the Combined Work, excluding any source code +for portions of the Combined Work that, considered in isolation, are +based on the Application, and not on the Linked Version. + + The "Corresponding Application Code" for a Combined Work means the +object code and/or source code for the Application, including any data +and utility programs needed for reproducing the Combined Work from the +Application, but excluding the System Libraries of the Combined Work. + + 1. Exception to Section 3 of the GNU GPL. + + You may convey a covered work under sections 3 and 4 of this License +without being bound by section 3 of the GNU GPL. + + 2. Conveying Modified Versions. + + If you modify a copy of the Library, and, in your modifications, a +facility refers to a function or data to be supplied by an Application +that uses the facility (other than as an argument passed when the +facility is invoked), then you may convey a copy of the modified +version: + + a) under this License, provided that you make a good faith effort to + ensure that, in the event an Application does not supply the + function or data, the facility still operates, and performs + whatever part of its purpose remains meaningful, or + + b) under the GNU GPL, with none of the additional permissions of + this License applicable to that copy. + + 3. Object Code Incorporating Material from Library Header Files. + + The object code form of an Application may incorporate material from +a header file that is part of the Library. You may convey such object +code under terms of your choice, provided that, if the incorporated +material is not limited to numerical parameters, data structure +layouts and accessors, or small macros, inline functions and templates +(ten or fewer lines in length), you do both of the following: + + a) Give prominent notice with each copy of the object code that the + Library is used in it and that the Library and its use are + covered by this License. + + b) Accompany the object code with a copy of the GNU GPL and this license + document. + + 4. Combined Works. + + You may convey a Combined Work under terms of your choice that, +taken together, effectively do not restrict modification of the +portions of the Library contained in the Combined Work and reverse +engineering for debugging such modifications, if you also do each of +the following: + + a) Give prominent notice with each copy of the Combined Work that + the Library is used in it and that the Library and its use are + covered by this License. + + b) Accompany the Combined Work with a copy of the GNU GPL and this license + document. + + c) For a Combined Work that displays copyright notices during + execution, include the copyright notice for the Library among + these notices, as well as a reference directing the user to the + copies of the GNU GPL and this license document. + + d) Do one of the following: + + 0) Convey the Minimal Corresponding Source under the terms of this + License, and the Corresponding Application Code in a form + suitable for, and under terms that permit, the user to + recombine or relink the Application with a modified version of + the Linked Version to produce a modified Combined Work, in the + manner specified by section 6 of the GNU GPL for conveying + Corresponding Source. + + 1) Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that (a) uses at run time + a copy of the Library already present on the user's computer + system, and (b) will operate properly with a modified version + of the Library that is interface-compatible with the Linked + Version. + + e) Provide Installation Information, but only if you would otherwise + be required to provide such information under section 6 of the + GNU GPL, and only to the extent that such information is + necessary to install and execute a modified version of the + Combined Work produced by recombining or relinking the + Application with a modified version of the Linked Version. (If + you use option 4d0, the Installation Information must accompany + the Minimal Corresponding Source and Corresponding Application + Code. If you use option 4d1, you must provide the Installation + Information in the manner specified by section 6 of the GNU GPL + for conveying Corresponding Source.) + + 5. Combined Libraries. + + You may place library facilities that are a work based on the +Library side by side in a single library together with other library +facilities that are not Applications and are not covered by this +License, and convey such a combined library under terms of your +choice, if you do both of the following: + + a) Accompany the combined library with a copy of the same work based + on the Library, uncombined with any other library facilities, + conveyed under the terms of this License. + + b) Give prominent notice with the combined library that part of it + is a work based on the Library, and explaining where to find the + accompanying uncombined form of the same work. + + 6. Revised Versions of the GNU Lesser General Public License. + + The Free Software Foundation may publish revised and/or new versions +of the GNU Lesser General Public License from time to time. Such new +versions will be similar in spirit to the present version, but may +differ in detail to address new problems or concerns. + + Each version is given a distinguishing version number. If the +Library as you received it specifies that a certain numbered version +of the GNU Lesser General Public License "or any later version" +applies to it, you have the option of following the terms and +conditions either of that published version or of any later version +published by the Free Software Foundation. If the Library as you +received it does not specify a version number of the GNU Lesser +General Public License, you may choose any version of the GNU Lesser +General Public License ever published by the Free Software Foundation. + + If the Library as you received it specifies that a proxy can decide +whether future versions of the GNU Lesser General Public License shall +apply, that proxy's public statement of acceptance of any version is +permanent authorization for you to choose that version for the +Library. + Copied: tags/mapstoragemanager-v001/changelog.txt (from rev 65,
