[Maria-discuss] Repos empty?
by William Edwards 15 Aug '22

15 Aug '22

Hello, The Debian repos @ https://mariadb.org/download/?t=repo-config don't seem to contain any packages and no Release file anymore. Last updated yesterday at 18:41 (IDK which timezone). E.g. http://ams2.mirrors.digitalocean.com/mariadb/repo/10.3/debian/dists/buster/… (the issue isn't with this specific mirror). When choosing a repo on mariadb.org, the error "An error occured. The mirrors could not be loaded." is shown. -- With kind regards, William Edwards

[Maria-discuss] Major upgrade instructions missing for Galera
by William Edwards 10 Aug '22

10 Aug '22

Hi, The documentation at https://mariadb.com/kb/en/upgrading-galera-cluster/ is missing major upgrade instructions > MariaDB 10.4. Someone else caught this as well: https://mariadb.com/kb/en/upgrading-from-104-to-105-galera-changes/ Is this intentional? -- With kind regards, William Edwards

[Maria-discuss] Speeding up MyRocks engine
by Jan Křístek 24 Jun '22

24 Jun '22

Hello, I have already given up on MyRocks but could someone give some hint to take back my decision?. I have a setup with a heavy insert load with potentially long records (up to a kilobyte or two). I cannot get more than about 300-400 inserts per second with MyRocks. With the Aria engine, it's reaching up to 1900 inserts/sec with the same setup. The only config changes for MyRocks are: rocksdb-override-cf-options='cf1={compression=kLZ4Compression;bottommost_compression=kLZ4Compression;}' rocksdb_allow_concurrent_memtable_write = ON rocksdb_default_cf_options=block_based_table_factory={cache_index_and_filter_blocks=1;filter_policy=bloomfilter:10:false;whole_key_filtering=1};level_compaction_dynamic_level_bytes=true;optimize_filters_for_hits=true;compaction_pri=kMinOverlappingRatio;compression=kLZ4Compression plugin-load-add=ha_rocksdb.so Both MyRocks and Aria are the same hardware, the same setup SSD with software Raid0 and LVM. With Aria I have switched on aria_group_commit to "soft" with 500 ms delay, as I understand, I might lose some data if the server is hard killed or crashes. I am willing to take the risk unless s/o suggests a major speedup for the MyRocks. I have switched TRANSACTIONAL=1 for the table. The table has partitions on both Aria and MyRocks. Thank you for any help in advance, Jan

[Maria-discuss] Change delimiter with server_audit plugin
by Philippe Maladjian 22 Jun '22

22 Jun '22

Hi there, In order to monitor a database and especially the requests that could be in error, I activated the server_audit plugin. Plugin setup: show global VARIABLES like '%server_audit%'; +-------------------------------+---------------------------------+ | Variable_name | Value | +-------------------------------+---------------------------------+ | server_audit_events | QUERY | | server_audit_excl_users | user | | server_audit_file_path | /var/log/mysql/server_audti.log | | server_audit_file_rotate_now | OFF | | server_audit_file_rotate_size | 1000000 | | server_audit_file_rotations | 9 | | server_audit_incl_users | user | | server_audit_logging | ON | | server_audit_mode | 0 | | server_audit_output_type | file | | server_audit_query_log_limit | 1024 | | server_audit_syslog_facility | LOG_USER | | server_audit_syslog_ident | mysql-server_auditing | | server_audit_syslog_info | | | server_audit_syslog_priority | LOG_ERR | +-------------------------------+---------------------------------+ My problem is that the separator between each value is the comma and bad luck it's the same separator as in the query. Example of a line: 20220622 08:35:03,sserver,user,localhost,14858,7002875,QUERY,database,'UPDATE sorderq SET `odlqty` = "6", `soqsta` = "3", `sdhnum` = "LIVHIL22062", `sddlin` = 24000 WHERE `sohnum` = "NORHIL220601" AND `soplin` = 24000 AND `soqseq` = 24000',0 [...] 20220622 08:35:03,server,user,localhost,14858,7002878,QUERY,database,'INSERT INTO sdeliveryd(`sdhnum`, `itmref`, `sddlin`, `netprinot`, `qty`, `rtnqty`, `tsicod0`, `tsicod1`, `tsicod2`, `tsicod3`, `tsicod4`, `rep1`) VALUES("LIVHIL22061", "1-11325", 26000, 0.0, "12", "0", "STA", "05", " ", " ", " ", "093")',0 It is the last field that interests me because it is the return code of the request. Now if I want to automate the error processing (last field <> 0) I simply cannot because due to the identical separator between the fields of the request and the fields of the log line, the number of columns varies and the return code never has the same position. Is it possible to change the field separator in the plugin? Thanks in advance
