QUESTION
I'm trying to get a full call tree of gpbackup from https://github.com/greenplum-db/gpbackup. I use runtime/pprof, not net/http/pprof, so as far as I know there shouldn't be any time limitations for collecting stats. I start pprof server in a very beginning of a program and stop it right before os.Exit() command. To collect stats I run gpbackup, it works as intended and I get cpu.prof output. Then I use pprof --nodecount=100000 gpb cpu.prof and generate a call tree with png command. The problem is that call tree lacks of major number of functions. For example, DoBackup() starts with logging functions, but they miss in a call tree, and there are lots of other functions that don't seem to appear either. How can I make pprof show every single call in a call tree?
ANSWER
Answered 2022-Jan-09 at 20:58By default pprof removes nodes with less than 0.5% of the CPU time and edges with less then 0.1% of the CPU time. You can ask pprof to not do this by supplying the -nodefraction=0 and -edgefraction=0 flags, this might solve your issue.
so as far as I know there shouldn't be any time limitations for collecting stats
Not fully true, runtime/pprof samples 100 times per second. Every time it samples, it captures the full stack-trace. So you might miss functions if they execute faster than 100th of a second and are not part of the stack frame of longer running functions.
You could copy StartCPUProfile and change the hz variable so it captures more often.
QUESTION
My team is planning for a DR solution and we need to sync data between Greenplum Databases in Production and DR sites.
We are running the 6.4 community edition. So tools like gpbackup and gprestore are not available.
pg_dump and pg_restore not an option because there is large data set involved. What is most suitable solution for our scenario?
ANSWER
Answered 2021-Oct-28 at 17:01gpbackup and gprestore is one way Greenplum users commonly keep two clusters in sync.
While gpbackup and gprestore doesn't ship with open source Greenplum Database, the tools are open source themselves and freely available from their own repository: https://github.com/greenplum-db/gpbackup
Due to Greenplum's distribution of data across segments, there is a requirement the DR cluster contain the same # of primary segments for a successful restore (although the # of segment hosts could differ).
A common approach we see Greenplum users implementing is backing up off cluster to a third party storage system (NFS, s3 compatible storage, etc..) and restoring to the destination/DR cluster from there.
There is an open source gpbackup_s3_plugin available here: https://github.com/greenplum-db/gpbackup-s3-plugin

QUESTION
In greenplum database while using gpbackup utility, I understand the heap tables, even when partitioned take full backup of the table even when we take incremental backup. But if I create the primary key or index on the heap table, shouldn't it start behaving as an append organized table? But it still takes full backup when --incremental is specified. Any reason for that?
...ANSWER
Answered 2020-Feb-10 at 14:58gpcrondump utility only compares the state of each table in the database against the last backup using state files. If there is any change in the state of the table since the last backup, it is marked dirty and is backed up during an incremental backup.
At the file level, heap tables, when vacuumed, have empty tuple slots that are filled by the next available tuple -- as soon as that slot is filled, that whole file has been modified.
As such, gpcrondump can only take incremental backups of "append-only" tables.
I would take a look at gpbackup - which has incremental backups on the roadmap and currently is operating much faster than gpcrondump for most backup operations.
QUESTION
I am using greenplum DB's gpbackup utility to take incremental backup of database, through following commands
1: Full backup
...ANSWER
Answered 2020-Feb-07 at 18:18You can find more details here, regarding the implementation of Greenplum's Incremental Backup
In short, incremental backups work best on AO partitioned tables. gpbackup will identify which partitions of AO tables have data changes since the last full or incremental backup, and add those to the backup set.
Heap tables are always fully backed up, regardless of the incremental flag is used.
In your use case, were you using AO partitioned tables?
