What is pgpool + + pgpool is a connection server for PostgreSQL. pgpool runs between + PostgreSQL's clients(front ends) and servers(back ends). A + PostgreSQL client can connect to pgpool as if it were a standard + PostgreSQL server. + + pgpool caches the connection to PostgreSQL server to reduce the + overhead to establish the connection to it. + + Also, pgpool could use two PostgreSQL servers for fail over. If the + first server goes down, pgpool will automatically switch to the + secondary server. + + Moreover, pgpool supports scheduled switch over. See + "9. Switchover" for more details. + +1.1 Anbout replication facility of pgpool + + pgpool could be used as a replication server. This allows real-time + backuping of the database to avoid disk failures. pgpool sends + exactly same query to each PostgreSQL servers to accomplish + replication. So pgpool can be regarded as a "synchronous + replication server". Currently pgpool supports up to 2 PostgreSQL + servers. + + Please note that some sort of quries such as random functions, OID, + XID, timestamp may not be replicated in exactly same value among + two servers. This is because qury results for these are local to + each PostgreSQL server. + + When one of PostgreSQL server goes down, pgpool tries to continue + serverce with live server. This is called "degeneration mode". + When you want to come back to the replication mode, please make + sure that the DB contens matche among two servers. The best way is + shutdown the live server and do a physical copy using rsync from + the live server to the dead server. Once the DB contents match you + start the two postmaster then restart pgpool. + +1.2 Avoiding deadlocks + + pgpool could send a query to the "master" server then send to + "secondary" server before master completes the query. This could + improve performace, there's a risk of deadlock however. To balance + the performace and risk, pgpool could operate in two modes. + + 1) "restrict" mode + + In this mode, pgpool wait for the completion of the master query + before sending a query to the secondary server. This is the safest + and default operating mode for pgpool. + + 2) using /*STRICT*/ keyword + + To achieve best performance, you could turn off the strict mode by + setting off to "pgpool_restrict" directive. To avoid deadlock, you + could insert a special keyword /*STRICT*/ in the beginning of each + deadlock-possible quries. Here is an example: + + /*STRICT*/ LOCK TABLE t1; + +1.3 what happens if a deadlock ocuurs? + + Since deadlocks mentioned above cannot be detected by PostgreSQL + itself, pgpool will abort the session if master or secondary does + not respond within certain period. The period can be changed by + setting replication_timeout directive. + +1.4 about load balancing mode + + If replication is enabled, you can enjoy the load balancing + capability of pgpool by enabling load_balance_mode in + pgpool.conf. If conditions below are all meet, SELECT queries are + distributed among the master and the slave server in random manner, + which will boost performance: + + 1) protocol version is V3. this means the backend must be + PostgreSQL 7.4 or later. + + 2) the query begins with "SELECT" or "select" (case is ignored). no + space is allowed before "SELECT". + + 3) SELECT query is not in a transatcion block. + + Please note that a SELECT may modify databases by calling a + updatable function. In this case you should NOT use the load + balancing. Othewise pgpool will fail due to the contents difference + between the master and the secondary database. You can avoid the + load balancing by putting spaces or comments in the begining of the + query. + + BTW, since the regression test includes such a SELECT (for example + "SELECT 'one' AS one, nextval('insert_seq');" in the constraints + test), the regression test will fail if the load balancing mode is + enabled. + +2. Advantages of pgpool + + There are some connection pool servers other than pgpool. This + section explains why you should use pgpool: + + 1) you do not need to modify your applications + + There are some connection pool servers which require special + API(Application Program Interface) to play with them. Since pgpool + looks like PostgreSQL server from the client's point of view, + existing PostgreSQL applications can be used without any + modifications. + + 2) any programming languages can be used + + Since pgpool is not an API, applications written in any languages + including PHP, Perl and Java can be used. + + 3) employing prefork architecture + + pgpool employing prefork architecture, meaning no need to start up + process for each connection from its clients, gives better + performance. + + 4) resource usage control + + pgpool can limit number of connections to PostgreSQL server. Users + could avoid too much load of PostgreSQL by using pgpool especially + under Web application environment. + + 5) fail over + + pgpool has a functionality so called "fail over". If the first + server goes down, pgpool will automatically switch to the secondary + server. + + 6) replication + + pgpool can be used as a replication server. + + 7) load balancing + + SELECT statement can be distributed among servers to gain more performance. + +3. Disadvantage of pgpool + + 1) overhead + + Any access to PostgreSQL must go through pgpool, which means some + overhead is added to each database access. In my testing using + pgbench shows 7 to 15% performance penalty. This number may + vary for each testing environment though. + + 2) not all libpq protocols are supported + + currently following protocols are not supported: + + o any authentication methods except "trust", "clear text password" + (replication mode) + + o any authentication methods except "trust", "clear text password", + "crypt", "md5" (non replication mode) + + 3) no access control to pgpool using pg_hba.conf + + Any client can connect to pgpool. If this is your concern, you + could limit access by using another software such as iptables. + +4. supported environments + + pgpool supports libpq protocol version 2(employed by PostgreSQL 6.4 + to 7.3). If you are going to use with PostgreSQL 7.2 or earlier, + you need to modify following line in pgpool.conf. + + 7.1 or earlier: + reset_query_list = 'ABORT' + + 7.2.x: + reset_query_list = 'ABORT, RESET ALL' + + 7.3 or later: + reset_query_list = 'ABORT, RESET ALL, SET SESSION AUTHORIZATION DEFAULT' + (currently the default value in pgpool.conf. so you don't need to + change it) + + Here are small lists from users where pgpool is running: + + Vine Linux 2.6r4 (kernel 2.4.22-0vl2.12)/PostgreSQL 8.0 + Vine Linux 2.6r4 (kernel 2.4.22-0vl2.12)/PostgreSQL 7.4.5 + Vine Linux 2.6r4 (kernel 2.4.22-0vl2.12)/PostgreSQL 7.4.3 + Vine Linux 2.6r4 (kernel 2.4.22-0vl2.12)/PostgreSQL 7.4.2 + Vine Linux 2.6r4 (kernel 2.4.22-0vl2.12)/PostgreSQL 7.3.7 + Vine Linux 2.6r4 (kernel 2.4.22-0vl2.12)/PostgreSQL 7.3.6 + Vine Linux 2.6r3 (kernel 2.4.22-0vl2.8)/PostgreSQL 7.4.2 + Vine Linux 2.6r3 (kernel 2.4.22-0vl2.8)/PostgreSQL 7.3.6 + Vine Linux 2.6CR (kernel 2.4.20-0vl29.1)/PostgreSQL 7.3.4 + RedHat Linux 9.0 (kernel 2.4.20)/PostgreSQL 7.3.6 + RedHat Linux 8.0 (kernel 2.4.18-14)/PostgreSQL 7.3.2 + RedHat Linux 6.2 (kernel 2.2.24)/PostgreSQL 7.2.1 + FreeBSD 5.2.1-RELEASE(AMD64)/PostgreSQL 7.4.3 + FreeBSD 5.2.1-RELEASE/PostgreSQL 7.3? + FreeBSD 4.7-RELEASE/PostgreSQL 7.2.4 + FreeBSD 4.2-RELEASE/PostgreSQL 7.3.2 + Sparc/Solaris8/PostgreSQL 7.3 + Sparc/Solaris8/PostgreSQL 7.4.3 + +5.

Setting up pgpool.conf + + pgpool.conf is the configuration file for pgpool. + + Copy pgpool.conf.sample as pgpool.conf and change it if neccessary. + + Here is a explanation of pgpool.conf's grammar. + + 1) configuration variables can be set by: + + item = value + + pair. + + 2) if the value is a numeric, just write numerics. If the value is + a string, you need to quote using single quote pair. example: + + 'foo' + + 3) empty lines are ignored + + 4) lines starting with # are ignored. + + + Here is a list of existing items: + + listen_addresses + + Specifies the addresses to listen on for TCP/IP connections. Set + to '*' for all configured IP interfaces, '' for no TCP/IP + connections, or else to a specific IP address or host name. The + default is 'localhost'. Note that connections via UNIX domain + sockets are always allowed. + + (For compatibility with earlier versions of pgpool, + allow_inet_domain_socket = 1 means listen_addresses = '*' and + allow_inet_domain_socket = 0 means listen_addresses = ''.) + + port + + the port number where pgpool is running on. Default value is 9999. + + backend_host_name + + the real PostgreSQL server name pgpool could connect. Default + value is '' (empty string), which means pgpool will connect via + UNIX domain sockets. Any string other than '' is considered as a + host name where the PostgreSQL server is running. In this case the + pg_hba.conf file must be properly set so that pgpool could connect + to. + + backend_port + + the port number where real PostgreSQL server is running on. Default + value is 5432. + + secondary_backend_host_name + + if you are going to use fail over or replication functionality of + pgpool, you need to set the hostname or ''. Default value is ''. + + secondary_backend_port + + if you are going to use fail over or replication functionality of + pgpool, you need to set the port number where PostgreSQL is running + on. Default value is 0, which means the fail over functionality is + disabled. + + num_init_children + + number of pgpool process initially forked. Default value is 32. + + max_pool + + number of connection pools each pgpool server process are keeping. + pgpool will make a new connection if there's no user name and + database name pair yet. Thus it is recommended that max_pool + exceeds the number of such that possible pairs. If it exceeds, the + oldest connection is discarded and the new connection uses the + slot. The default value is 4. + + note that the total number of connections to the PostgreSQL server + can be calculated by following: + + num_init_children*max_pool + + child_life_time + + Life of a idle child process in seconds. This will prevent unwanted + memory leaks or other problems. Default is 300. Set it to 0 + disables this feature. + + connection_life_time + + life time for each idle connection in seconds. 0 means the life + time is forever. The default value is 0. + + logdir + + the directory name to store pgpool's log files. Currently only a + file named pgpool.pid(has pgpool's process id) is stored. The + default value for logdir is '/tmp'. + + replication_mode + + set this true if you are going to use replication + functionality. Default is false. + + replication_strict + + If true, pgpool will wait for the completion of the master query + before sending a query to the secondary server. This is the safest + and default operating mode for pgpool. Default is true. + + replication_timeout + + In non strict replication mode, there will be a chance of + deadlock. pgpool will abort the session if master or secondary does + not respond within this milli seconds. if set to 0, timeout is + disabled. + + load_balance_mode + + Perform load balancing for SELECT. Default is false. + + weight_master + weight_secondary + + load balance weight for master and secondary. actual weight is + calculated by weight_master:weight_secondary. For example both + + weight_master = 10 and weight_secondary = 5 + weight_master = 4 and weight_secondary = 2 + + are regarded as master has double the weight comparing with + secondary. master and secondary have same weight in the default. + + replication_stop_on_mismatch + + Stop replication mode on data mismatch between master and + secondary. Default is false. + + reset_query_list + + semicolon separated SQL commands to be issued at the end of + session. Default is as following: + + reset_query_list = 'ABORT; RESET ALL; SET SESSION AUTHORIZATION DEFAULT' + + You may add you own SQL commands to the list. Please note that + above all queries may not be accepted by all PostgreSQL + versions(see "4. supported environmets" for more details). + + Note that "ABORT" will not be issued if the backend is 7.4 or later + and the session is not in a transaction block. + + print_timestamp + + If true timestamp is added to each log line. Default value is true. + + master_slave_mode + + Run in master/slave mode. See 14 for more details. Default value is + false. This mode is not compatible with replication_mode. + + connection_cache + + If true, cache connections to PostgreSQL. Default value is true. + + health_check_timeout + + pgpool does "health check" periodically to detect PostgreSQL + servers down, network communication problems or as such. If + something is going wrong, pgpool will automatically run into fail + over or degeneration mode. + + This parameter specifies the timeout value in seconds to avoid hung + up in the health checking. The default is 20. 0 means no timeout. + + The health checking actually connects to PostgreSQL as if it's an + ordinaly PostgreSQL client. Thus you may need to increase the + max_connections parameter of PostgreSQL. + + health_check_period + + Specifies the interval for next health checking. 0 means no health + checking. The default is 0(i.e. no health checking). + + health_check_user + + PostgreSQL user name for the health checking. + +7. Starting pgpool + + The simplist way to start pgpool is: + + $ pgpool + + pgpool will load /usr/local/etc/pgpool.conf. + + available options for pgpool are: + + -f path + + the path to the configuration file. + + -n + + do not start as daemon. Error messages go to stdout or stderr. Thus + you could play with utilities such as logger and rotatelogs. You + need to run in background explicitly if you use this option. + + -d + + lots of debugging messages come out + + -h + + print the help message and quit + +8. Stopping pgpool + + You can stop pgpool by using "stop" option: + + $ pgpool [-f config_file] -m {s[mart]|f[ast]|i[mmediate]} stop + + If there's any live connection from frontend, it will wait until + the connection terminated. + + To force it to be stopped, try: + + $ pgpool -m f[ast] stop + + or + + $ pgpool -m i[mmediate] stop + +9. switchover + + For maintenance purpose, scheduled switching or degenration is + supported. + + $ pgpool [-f config_file] [-s {m[aster]|s[econdary]] switch + + If [-m {s[mart]|f[ast]|i[mmediate]}] part is omitted, master goes + down. To stop secondary try: + + $ pgpool [-f config_file] -s s[econdary] switch + + Note that "s[econdary]" measn "s" or "secondary". + + If there's only one PostgreSQL server, pgpool switch will just + restart pgpool child processes. + +10. how to get logging + + You could save messages from pgpool to a file by starting it with + -n option: + + pgpool -n >& /tmp/pgpool.log & + + If you prefer to log to syslog, do like this: + + pgpool -n 2>&1 |logger -t pgpool -p local0.info& + +11. getting internal status of pgpool + + You could use psql or whatever to obtain the internal status of + pgpool by issuing a special SQL command: + + psql -p 9999 -c 'show pool_status' template1 + + item | value | description +------------------------------+------------------------------------------------------+------------------------------------------------------------------------ + listen_addresses | * | host name(s) or IP address(es) to listen to + port | 9999 | pgpool accepting port number + socket_dir | /tmp | pgpool socket directory + backend_host_name | | master backend host name + backend_port | 5432 | master backend port number + secondary_backend_host_name | | secondary backend host name + secondary_backend_port | 0 | secondary backend port number + num_init_children | 1 | # of children initially pre-forked + child_life_time | 300 | if idle for this seconds, child exits + connection_life_time | 0 | if idle for this seconds, connection closes + max_pool | 4 | max # of connection pool per child + logdir | /tmp | logging directory + backend_socket_dir | /tmp | Unix domain socket directory for the PostgreSQL server + replication_mode | 0 | non 0 if operating in replication mode + replication_strict | 1 | non 0 if operating in strict mode + replication_timeout | 5000 | if secondary does not respond in this milli seconds, abort the session + load_balance_mode | 0 | non 0 if operating in load balancing mode + weight_master | 1.000000 | weight of master + weight_secondary | 1.000000 | weight of secondary + replication_stop_on_mismatch | 0 | stop replication mode on fatal error + reset_query_list | ABORT; RESET ALL; SET SESSION AUTHORIZATION DEFAULT; | queries issued at the end of session + print_timestamp | 1 | if true print time stamp to each log line + master_slave_mode | 0 | if true, operate in master/slave mode + connection_cache | 1 | if true, cache connection pool + health_check_timeout | 20 | health check timeout + health_check_period | 0 | health check period + current_backend_host_name | | current master host name + current_backend_port | 5432 | current master port # + replication_enabled | 0 | non 0 if actually operating in replication mode + master_slave_enabled | 0 | non 0 if actually operating in master/slave + num_reset_queries | 3 | number of queries in reset_query_list +(31 rows) + +12.

Playing with benchmarking + + Here is a brief explanation how to play with benchmarking using pgbench/PHP/ab. + + Initialize the pgbench database. + + $ pgbench -i test + + Prepare PHP script.

To enable this mode, you need to set + secondary host, and set true to master_slave_mode and + load_balance_mode. Depending on the kind of qureries, pgpool + operates as follows: + + 1) if all below are satisfies, quries sent to both master and + secondary with load balance manner. + + - PostgreSQL 7.4 or later + - the query begins with "SELECT"(case insensitive) + - not in a transaction block + + 2) in all other case, quries are sent to only master + diff --git a/README.euc_jp b/README.euc_jp new file mode
