That means that there is currently no 64-bit build -for Windows (but a 32-bit executable should work fine anywhere). - -To build pgreplay, you will need the `pg_config` utility. If you installed -PostgreSQL using installation packages, you will probably have to install -the development package that contains `pg_config` and the header files. - -If `pg_config` is on the `PATH`, the installation process will look like this: - -- unpack the tarball -- `./configure` -- `make` -- `make test` (optional, described below) -- `make install` (as superuser) - -If your PostgreSQL installation is in a nonstandard directory, you -will have to use the `--with-postgres=` -option of `configure`. - -Unless you link it statically, pgreplay requires the PostgreSQL client -shared library on the system where it is run. - -The following utilities are only necessary if you intend to develop pgreplay: -- autoconf 2.62 or better to generate `configure` -- GNU tar to `make tarball` (unless you want to roll it by hand) -- groff to make the HTML documentation with `make html` - -Docker ------- - -The `Dockerfile` provided with the software can be used as a starting -point for creating a container that runs pgreplay.

For this you need psql installed and a PostgreSQL server -running (on this or another machine) so that the following command -will succeed: - - psql -U postgres -d postgres -l - -You can set up the `PGPORT` and `PGHOST` environment variables and a password -file for the user if necessary. - -There have to be a login roles named `hansi` and `postgres` in the database, -and both users must be able to connect without a password. Only `postgres` -will be used to run actual SQL statements. The regression test will create -a table `runtest` and use it, and it will drop the table when it is done. - -Usage -===== - -First, you will need to record your real-life workload. -For that, set the following parameters in `postgresql.conf`: - -- `log_min_messages = error` (or more) - (if you know that you have no cancel requests, `log` will do) -- `log_min_error_statement = log` (or more) -- `log_connections = on` -- `log_disconnections = on` -- `log_line_prefix = '%m|%u|%d|%c|'` (if you don't use CSV logging) -- `log_statement = 'all'` -- `lc_messages` must be set to English (the encoding does not matter) -- `bytea_output = escape` (from version 9.0 on, only if you want to replay - the log on 8.4 or earlier) - -It is highly recommended that you use CSV logging, because anything that -the PostgreSQL server or any loaded modules write to standard error will -be written to the stderr log and might confuse the parser. - -Then let your users have their way with the database. - -Make sure that you have a `pg_dumpall` of the database cluster from the time -of the start of your log file (or use the `-b` option with the time of your -backup). Alternatively, you can use point-in-time-recovery to clone your -database at the appropriate time. - -When you are done, restore the database (in the "before" state) to the -machine where you want to perform the load test and run pgreplay against -that database. - -Try to create a scenario as similar to your production system as -possible (except for the change you want to test, of course). For example, -if your clients connect over the network, run pgreplay on a different -machine from where the database server is running. - -Since passwords are not logged (and pgreplay consequently has no way of -knowing them), you have two options: either change `pg_hba.conf` on the -test database to allow `trust` authentication or (if that is unacceptable) -create a password file as described by the PostgreSQL documentation. -Alternatively, you can change the passwords of all application users -to one single password that you supply to pgreplay with the `-W` option. - -Limitations -=========== - -pgreplay can only replay what is logged by PostgreSQL. -This leads to some limitations: - -- `COPY` statements will not be replayed, because the copy data are not logged. - I could have supported `COPY TO` statements, but that would have imposed a - requirement that the directory structure on the replay system must be - identical to the original machine. - And if your application runs on the same machine as your database and they - interact on the file system, pgreplay will probably not help you much - anyway. -- Fast-path API function calls are not logged and will not be replayed. - Unfortunately, this includes the Large Object API. -- Since the log file is always written in the database encoding (which you - can specify with the `-E` switch of pgreplay), all `SET client_encoding` - statements will be ignored. -- If your cluster contains databases with different encoding, the log file - will have mixed encoding as well. You cannot use pgreplay well in such - an environment, because many statements against databases whose - encoding does not match the `-E` switch will fail. -- Since the preparation time of prepared statements is not logged (unless - `log_min_messages` is `debug2` or more), these statements will be prepared - immediately before they are first executed during replay. -- All parameters of prepared statements are logged as strings, no matter - what type was originally specified during bind. - This can cause errors during replay with expressions like `$1 + $2`, - which will cause the error `operator is not unique: unknown + unknown`. - -While pgreplay makes sure that commands are sent to the server in the -order in which they were originally executed, there is no way to guarantee -that they will be executed in the same order during replay: Network -delay, processor contention and other factors may cause a later command -to "overtake" an earlier one. While this does not matter if the -commands don't affect each other, it can lead to SQL statements hitting -locks unexpectedly, causing replay to deadlock and "hang". -This is particularly likely if many different sessions change the same data -repeatedly in short intervals. - -You can work around this problem by canceling the waiting statement with -pg_cancel_backend. Replay should continue normally after that. - -Implementation details -====================== - -pgreplay will track the "session ID" associated with each log entry (the -session ID uniquely identifies a database connection). -For each new session ID, a new database connection will be opened during -replay. Each statement will be sent on the corresponding connection, so -transactions are preserved and concurrent sessions cannot get in each -other's way. - -The order of statements in the log file is strictly preserved, so there -cannot be any race conditions caused by different execution speeds on -separate connections. On the other hand, that means that long running -queries on one connection may stall execution on concurrent connections, -but that's all you can get if you want to reproduce the exact same -workload on a system that behaves differently. - -As an example, consider this (simplified) log file: - - session 1|connect - session 2|connect - session 1|statement: BEGIN - session 1|statement: SELECT something(1) - session 2|statement: BEGIN - session 2|statement: SELECT something(2) - session 1|statement: SELECT something(3) - session 2|statement: ROLLBACK - session 2|disconnect - session 1|statement: COMMIT - session 2|disconnect - -This will cause two database connections to be opened, so the `ROLLBACK` in -session 2 will not affect session 1. -If `SELECT something(2)` takes longer than expected (longer than it did in -the original), that will not stall the execution of `SELECT something(3)` -because it runs on a different connection. The `ROLLBACK`, however, has to -wait for the completion of the long statement. Since the order of statements -is preserved, the `COMMIT` on session 1 will have to wait until the `ROLLBACK` -on session 2 has started (but it does not have to wait for the completion of -the `ROLLBACK`). - -pgreplay is implemented in C and makes heavy use of asynchronous command -processing (which is the reason why it is implemented in C). -This way a single process can handle many concurrent connections, which -makes it possible to get away without multithreading or multiprocessing. - -This avoids the need for synchronization and many portability problems. -But since TINSTAAFL, the choice of C brings along its own portability -problems. Go figure. - -Replay file format ------------------- - -The replay file is a binary file, integer numbers are stored in network -byte order. - -Each record in the replay file corresponds to one database operation -and is constructed as follows: -- 4-byte `unsigned int`: log file timestamp in seconds since 2000-01-01 -- 4-byte `unsigned int`: fractional part of log file timestamp in microseconds -- 8-byte `unsigned int`: session id -- 1-byte `unsigned int`: type of the database action: - - 0 is connect - - 1 is disconnect - - 2 is simple statement execution - - 3 is statement preparation - - 4 is execution of a prepared statement - - 5 is cancel request -- The remainder of the record is specific to the action, strings are stored - with a preceeding 4-byte unsigned int that contains the length. - Read the source for details. -- Each record is terminated by a new-line character (byte 0x0A). - - -Using for polardb -====== -- make sure pg_stat_statements, plpgsql, system_stats was installed.system_stats install methods refer to https://github.com/EnterpriseDB/system_stats. -```sql -postgres=# create extension plpgsql; -postgres=# create extension pg_stat_statements; -postgres=# create extension system_stats; -postgres=# \dx - List of installed extensions - Name | Version | Schema | Description ---------------------+---------+------------+----------------------------------------------------------- - pg_stat_statements | 1.6 | public | track execution statistics of all SQL statements executed - plpgsql | 1.0 | pg_catalog | PL/pgSQL procedural language - system_stats | 1.0 | public | EnterpriseDB system statistics for PostgreSQL -(3 rows) -``` - -- postgres.conf configure -```sh -# log setting for gpreplay -log_min_messages = error -# (if you know that you have no cancel requests, log will do) -log_min_error_statement = log -log_connections = on -log_disconnections = on -log_line_prefix = '%t|%u|%d|%c|' -log_statement = 'all' -# lc_messages must be set to English (the encoding does not matter) -bytea_output = escape -# (from version 9.0 on, only if you want to replay the log on 8.4 or earlier) - -polar_enable_log_search_path = true -polar_enable_log_parameter_type = true -``` -- run read audit log from $PGDATA/log/replay_xxx.log and replay sql to databse, reporting monitor info every 3 seconds. -```sh -./pgreplay -P -m 3 -h 127.0.0.1 -p 5432 -W benchmarksql $PGDATA/log/replay_xxx.log -``` -Support -======= - -If you have a problem or question, the preferred option is to [open an -issue](https://github.com/laurenz/pgreplay/issues). -This requires a GitHub account. - -Professional support can be bought from -[CYBERTEC PostgreSQL International GmbH](https://www.cybertec-postgresql.com/). - -TODO list -========= - -Nothing currently.

NAME - -

- - -

pgreplay -− PostgreSQL log file replayer for performance -tests

- -

SYNOPSIS - -

- - - -

pgreplay -[parse options] [replay options] [-d -level] [infile]
-pgreplay -f [parse options] [-o -outfile] [-d level] [infile] -
-pgreplay -r [replay options] [-d -level] [infile]

- -

DESCRIPTION - -

- - - -

pgreplay -reads a PostgreSQL log file (not a WAL file), -extracts the SQL statements and executes them in the same -order and relative time against a PostgreSQL database -cluster. A final report gives you a useful statistical -analysis of your workload and its execution.

- -

In the first -form, the log file infile is replayed at the time it -is read.

- -

With the --f option, pgreplay will not execute the -statements, but write them to a ‘replay file’ -outfile that can be replayed with the third form.

- -

With the --r option, pgreplay will execute the -statements in the replay file infile that was created -by the second form.

- -

If the -execution of statements gets behind schedule, warning -messages are issued that indicate that the server cannot -handle the load in a timely fashion. The idea is to replay a -real-world database workload as exactly as possible.

- -

To create a log -file that can be parsed by pgreplay, you need to set -the following parameters in postgresql.conf:

- - -

log_min_messages=error -(or more)
-log_min_error_statement=log (or more)
-log_connections=on
-log_disconnections=on
-log_line_prefix='%m|%u|%d|%c|' (if you don't use CSV -logging)
-log_statement='all'
-lc_messages must be set to English (encoding does not -matter)
-bytea_output=escape (from version 9.0 on, only if you -want to replay the log on 8.4 or earlier)

- -

The database -cluster against which you replay the SQL statements must be -a clone of the database cluster that generated the logs from -the time immediately before the logs were -generated.

- - -

pgreplay -is useful for performance tests, particularly in the -following situations:

- - - - - - - - - - - - -
- - -

*

 - - -

You want to compare the performance of your PostgreSQL -application on different hardware or different operating -systems.

- - -

*

 - - -

You want to upgrade your database and want to make sure -that the new database version does not suffer from -performance regressions that affect you.

- -

Moreover, -pgreplay can give you some feeling as to how your -application might scale by allowing you to try to -replay the workload at a higher speed. Be warned, though, -that 500 users working at double speed is not really the -same as 1000 users working at normal speed.

- -

OPTIONS - -

- - -

Parse -options:

- - - - - - - -
- - -

-c

 - - -

Specifies that the log file is -in 'csvlog' format (highly recommended) and not in 'stderr' -format.

- -

-b timestamp

- -

Only log entries greater or -equal to that timestamp will be parsed. The format is -YYYY-MM-DD HH:MM:SS.FFF like in the log file. An -optional time zone part will be ignored.

- -

-e timestamp

- -

Only log entries less or equal -to that timestamp will be parsed. The format is -YYYY-MM-DD HH:MM:SS.FFF like in the log file. An -optional time zone part will be ignored.

- - - - - - - -
- - -

-q

 - - -

Specifies that a backslash in a simple string literal -will escape the following single quote. This depends on -configuration options like -standard_conforming_strings and is the default for -server version 9.0 and less.

- -

-D database

- -

Only log entries related to the -specified database will be parsed (this option can be -specified multiple times for more than one database).

- -

-U username

- -

Only log entries related to the -specified username will be parsed (this option can be -specified multiple times for more than one user).

- -

Replay -options:
--h hostname

- -

Host name where the target -database cluster is running (or directory where the UNIX -socket can be found). Defaults to local connections.
-This works just like the -h option of -psql.

- -

-p port

- -

TCP port where the target -database cluster can be reached.

- -

-W password

- -

By default, pgreplay -assumes that the target database cluster is configured for -trust authentication. With the -W option you -can specify a password that will be used for all users in -the cluster.

- -

-s factor

- -

Speed factor for replay, by -default 1. This can be any valid positive floating point -number. A factor less than 1 will replay the workload -in ‘slow motion’, while a factor greater -than 1 means ‘fast forward’.

- -

-E encoding

- -

Specifies the encoding of the -log file, which will be used as client encoding during -replay. If it is omitted, your default client encoding will -be used.

- - - - - - - - - - - - -
- - -

-j

 - - -

If all connections are idle, jump ahead to the next -request instead of sleeping. This will speed up replay. -Execution delays will still be reported correctly, but -replay statistics will not contain the idle time.

- - -

-n

 - - -

Dry run mode. No connections to the server are made. -Useful for checking if the replay file is corrupt or to get -statistics about the replay file (number of statements, -original duration, ...)

- -

-X options

- -

Extra connection options for -replay connections. These must be libpq connection options -specified in the format ‘option=value -[...]’.

- -

Output -options:
--o outfile

- -

specifies the replay file where -the statements will be written for later replay.

- -

Debug -options:
--d level

- -

Specifies the trace level -(between 1 and 3). Increasing levels will produce more -detailed information about what pgreplay is -doing.

- - - - - - - - -
- - -

-v

 - - -

Prints the program version and exits.

 -
- -

ENVIRONMENT - -

- - - - - - - - - - - - - - - -
- - -

PGHOST

 - - -

Specifies the default value for -the -h option.

 -
- - -

PGPORT

 - - -

Specifies the default value for the -p -option.

 -
- -

PGCLIENTENCODING

- -

Specifies the default value for -the -E option.

- -

LIMITATIONS - -

- - - -

pgreplay -can only replay what is logged by PostgreSQL. This leads to -some limitations:

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
- - -

*

 - - -

COPY statements will not be replayed, because the -copy data are not logged.

- - -

*

 - - -

Fast-path API function calls are not logged and will not -be replayed. Unfortunately, this includes the Large Object -API.

- - -

*

 - - -

Since the log file is always in the server encoding -(which you can specify with the -E switch of -pgreplay), all SET client_encoding statements -will be ignored.

- - -

*

 - - -

Since the preparation time of prepared statements is not -logged (unless log_min_messages is debug2 or -more), these statements will be prepared immediately before -they are first executed during replay.

- - -

*

 - - -

Because the log file contains only text, query -parameters and return values will always be in text and -never in binary format. If you use binary mode to, say, -transfer large binary data, pgreplay can cause -significantly more network traffic than the original -run.

- - -

*

 - - -

Sometimes, if a connection takes longer to complete, the -session ID unexpectedly changes in the PostgreSQL log file. -This causes pgreplay to treat the session as two -different ones, resulting in an additional connection. This -is arguably a bug in PostgreSQL.
