### PRIMARY SIDE SETTINGS
# Plugin used to perform replication.
# Leave it empty to use built-in replication.
#
# plugin =
# Pattern (regular expression) that defines what tables must be included into
# replication. By default, all tables are replicated.
#
# include_filter =
# Pattern (regular expression) that defines what tables must be excluded from
# replication. By default, all tables are replicated.
#
# exclude_filter =
# Boolean parameters describing how replication errors must be handled.
#
# log_errors = true # All errors (and warnings) are written to replication.log
# report_errors = false # Errors are returned to the client application
# disable_on_error = true # Replication is disabled after error
### Parameters specific for built-in replication
# Size of the local buffer used to accumulate changes that can be
# deferred until the transaction commit/rollback. The bigger this value
# the less disk access concurrency (related to journal IOPS) happens.
#
# For synchronous replication, it also affects number of network round-trips
# between primary and replica hosts.
# However, a larger buffer costs a longer replication "checkpoints"
# (delay to synchronize the original database with its replica at commit).
#
# buffer_size = 1048576 # 1MB
# Directory to store replication journal files.
#
# journal_directory =
# Prefix for replication journal file names. It will be automatically suffixed
# with an ordinal sequential number. If not specified, database filename
# (without path) is used as a prefix.
#
# journal_file_prefix =
# Maximum allowed size for a single replication segment.
#
# journal_segment_size = 16777216 # 16MB
# Maximum allowed number of full replication segments. Once this limit is reached,
# the replication process is temporarily delayed to allow the archiving to catch up.
# If any of the full segments is not archived during one minute,
# the replication fails with an error.
#
# Zero means an unlimited number of segments pending archiving.
#
# journal_segment_count = 8
# Delay, in milliseconds, to wait before the changes are synchronously flushed
# to the journal (usually at commit time). This allows multiple concurrently committing
# transactions to amortise I/O costs by sharing a single flush operation.
#
# Zero means no delay, i.e. "group flushing" is disabled.
#
# journal_group_flush_delay = 0
# Directory for the archived journal files.
#
# Directory to store archived replication segments.
# It also defines the $(archpathname) substitution macro (see below).
#
# journal_archive_directory =
# Program (complete command line with arguments) that is executed when some
# replication segment gets full and needs archiving.
#
# This program MUST return zero ONLY if archiving has been performed successfully.
# In particular, it MUST return non-zero if the target archive already exists.
#
# Special predefined macros are available:
# $(filename) - file name (without path) of the journal segment being archived
# $(pathname) - full path name of the journal segment being archived
# same as journal_directory + $(filename)
# $(archivepathname) - suggested full path name for the archived segment
# same as journal_archive_directory + $(filename)
#
# Simplest configuration is to use standard OS commands for archiving, e.g.:
#
# Linux: "test ! -f $(archivepathname) && cp $(pathname) $(archivepathname)"
# or
# Windows: "copy $(pathname) $(archivepathname)"
#
# journal_archive_command =
# Timeout, in seconds, to wait until incomplete segment is scheduled for archiving.
# It allows to minimize the replication gap if the database is modified rarely.
#
# Zero means no intermediate archiving, i.e. segments are archived only after
# reaching their maximum size (defined by journal_segment_size).
#
# journal_archive_timeout = 60
# Connection string to the replica database (used for synchronous replication only).
# Expected format:
#
# [<login>:<password>@]<database connection string>
#
# Examples:
#
# server2:replica
# john:smith@server2:replica
# server2:/my/replica/database.fdb
# john:smith@server2:/my/replica/database.fdb
#
# Multiple entries are allowed (for different synchronous replicas).
#
# sync_replica =
### REPLICA SIDE SETTINGS
# Directory to search for the journal files to be replicated.
#
# journal_source_directory =
# Filter to limit replication to the particular source database (based on its GUID).
# Expected format: "{XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}"
# Note that double quotes are mandatory, as well as curly braces.
#
# source_guid =
# If enabled, replication.log contains the detailed log of operations performed
# by the replication server. Otherwise (by default), only errors and warnings are logged.
#
# verbose_logging = false
# Timeout (in seconds) to wait before scanning for the new replication segments.
#
# It's used to pause the replication server when all existing segments are already applied
# to the replica database and there are no new segments in the specified directory.
#
# apply_idle_timeout = 10
# Timeout (in seconds) to wait before retrying to apply the queued segments after error.
#
# It's used to pause the replication server after some critical error happened during replication.
# In this case, the server disconnects from the replica database, sleeps for the specified timeout,
# then reconnects back and tries to re-apply the latest segments from the point of failure.
#
# apply_error_timeout = 60
}
#
# Database-specific settings belong here, e.g.
#
# (for the primary side)
#
# database = /your/db.fdb
# {
# (for synchronous replication)
#
# sync_replica = sysdba:masterkey@otherhost:/your/replica.fdb
#
# (for asynchronous replication)
#
# journal_directory = /your/db/journal
# journal_archive_directory = /your/db/archive
# journal_archive_timeout = 10
# }
#
# (for the replica side)
#
# database = /your/db.fdb
# {
# journal_source_directory = /your/db/source
# }
