+
+Two way replication on a single "table" is availabe in Lotus Notes. In
+Notes, every record has a time-stamp, which contains the time of the
+last update. (It also has a creation timestamp.) During replication,
+timestamps are compared at the row/record level, and compared with the
+timestamp of the last replication. If, for corresponding rows in two
+replicas, the timestamp of one row is newer than the last replication,
+the contents of this newer row is copied to the other replica. But if
+both of the corresponding rows have newer timestamps, there is a
+problem. The Lotus Notes solution is to:
+ 1. send a replication conflict message to the Notes Administrator,
+which message contains full copies of both rows.
+ 2. copy the newest row over the less new row in the replicas.
+ 3. there is a mechanism for the Administrator to reverse the default
+decision in 2, if the semantics of the message history, or off-line
+investigation indicates that the wrong decision was made.
+
+In practice, the Administrator is not overwhelmed with replication
+conflict messages because updates usually only originate at the site
+that originally created the row. Or updates fill only fields that were
+originally 'TBD'. The full logic is perhaps more complicated than I have
+described here, but it is already complicated enough to give you an idea
+of what you're really being asked to do. I am not aware of a supplier of
+relational database who really supports two way replication at the level
+that Notes supports it, but Notes isn't a relational database.
+
+The difficulty of the position that you appear to be in is that
+management might believe that the full problem is solved in brand X
+RDBMS, and you will have trouble convincing management that this is not
+really true.

+
+I have written some thoughts on the concept of tablespace
+down. I would be happy to get some comments on it.
+
+-----------------------------------------------------------------
+ Implementation of tablespaces within PostgreSQL
+- a brainstorming paper designed for general discussion -
+
+by Martin Neumann, 2000/3/15
+
+
+1. What are tablespaces?
+-------------------------
+
+Tablespaces make it possible to distribute storage objects
+over multiple points of storage (POS). Therefor one could
+say a tablespace can be a POS.
+
+Example:
+
+tablespace_a -----> /mnt/raid/arena0/
+tablespace_b -----> /mnt/raid/emc0/
+
+Tablespaces can also store their data on other tablespaces:
+
+tablespace_c -----> tablespace_b
+
+This is quite interessting for administration purposes.
+
+
+2. What are its advantages?
+----------------------------
+
+As you can choose a different tablespace for every storage
+object (table, index etc.) it is easy to improve the following
+aspects of your system:
+
+ - Reliability
+
+ You can put storage objects (mostly tables) you strongly depend
+ on onto a more reliable tablespace (mirrored RAID or perhaps
+ simply a directory which gets backuped more often than others).
+
+ - Speed
+
+ You can put storage objects you rarely need onto a rather slow
+ tablespace and keep your quick tablespaces clean from this.
+
+ A fast, but more expensive RAID-Stripeset can be used more
+ efficiently as it doesn't get filled with non-performance
+ sensitive data.
+
+ But also distributing storage objects which have equal needs
+ in sense of speed onto different tablespaces makes sense as
+ you gain more speed by distributing data over more than one
+ harddisk spindle.
+
+ - Manageability
+
+ You can grant and revoke rights on base of a tablespace.
+
+ As every storage object belongs to exactly one tablespace,
+ you can easily group storage objects using a tablespace.
+
+
+3. What about disk I/O?
+------------------------
+
+Tablespaces tell the storage manager only where to store
+the data, not how. This is the reasonable way.
+
+
+4. Usage
+---------
+
+CREATE TABLESPACE tsname TYPE storage_type storage_options
+
+Examples:
+
+CREATE TABLESPACE tsemc0
+ TYPE classic DIRECTORY /mnt/raid/emc0 NOFSYNC
+
+CREATE TABLESPACE tsarena0 TYPE raw DEVICE /dev/araid/0
+ MINSIZE 128 MAXSIZE 4096 GROW 4 32 SHRINK 2 32
+ BLOCKSIZE 16384
+
+CREATE TABLESPACE quick0 TYPE link TABLESPACE tsarena0;
+
+--
+
+CREATE TABLE tbname ( ... ) TABLESPACE tsname;
+
+Examples:
+
+CREATE TABLE foo (
+ id int4 NOT NULL UNIQUE,
+ name text NOT NULL
+) TABLESPACE tsemc0;
+
+CREATE TABLE bar (
+ id int4 NOT NULL UNIQUE,
+ name text NOT NULL
+) TABLESPACE default;
+
+If the tablespace isn't given, the storage objects gets created
+in the "default" tablespace.
+
+"default" is the PostgreSQL's default tablespace and the only one
+which has to exist on each system.
+
+--
+
+ALTER TABLESPACE tsname tssettings
+
+Examples:
+
+ALTER TABLESPACE tsemc0 DIRECTORY /mnt/raid/emc1
+
+
+NOTE: altering tablespaces without recreating the contained
+storage objects introduces many problems.
+Realisation is difficult and won't be my first goal.
+
+--
+
+DROP TABLESPACE tsname [FORCE]
+
+Examples:
+
+DROP TABLESPACE tsarena0
+
+This will immediately remove the tablespace tsarena0
+if it contains no storage objects.
+
+If it still contains some the tablespace is marked for
+deletion.
+
+This means:
+1. you can't create new storage objects in the tablespace
+2. if the last storage object inside gets dropped, the
+ tablespace will be removed.
+
+
+DROP TABLESPACE tsarena0 FORCE
+
+This will remove the tablespace including all contained
+storage objects immediately.
+
+--
+
+VACUUM tsname
+
+Example:
+
+VACUUM tsemc1
+
+This will vacuum a single tablespace with all contained
+storage objects.
