Combine pgreplay with a specialized analysis +program like [pgBadger](https://pgbadger.darold.net/) for that. + +As an additional feature, pgreplay lets you split the replay in two +parts: you can parse the log file and create a "replay file", which +contains just the statements to be replayed and is hopefully much +smaller than the original log file. +Such a replay file can then be run against a database. + +pgreplay is written by Laurenz Albe and is inspired by "Playr" +which never made it out of Beta. + +Installation +============ + +pgreplay needs PostgreSQL 8.0 or better. + +It is supposed to compile without warnings and run on all platforms +supported by PostgreSQL. +Since I only got to test it on Linux, AIX, FreeBSD and Windows, there may be +problems with other platforms. I am interested in reports and fixes for +these platforms. +On Windows, only the MinGW build environment is supported (I have no +other compiler). 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.

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.

+ +
