v2.0.1
ProxySQL 2.0.1 release date: 2019-01-25
Compared to v1.4, ProxySQL 2.0 introduces the following new features, bugs fixes and enhancements
Dependencies
New dependencies are added to ProxySQL, all statically linked:
- libev
- openssl
- google-coredumper
Upgraded dependencies:
- MariaDB Connector C baseline upgraded to 3.0.2
- jemalloc upgraded to 4.5.1
- SQLite upgraded to 3.19.2
- libconfig upgraded to 1.7.2
Operating System changes
- Support for RHEL / CentOS 5, Debian7 and Ubuntu 12 has been discontinued
- ProxySQL now runs under the
proxysql
user, the/var/lib/proxysql
directory and contents now belong to this user / group - Support for systemd has been introduced for Debian 9 and Ubuntu 18
mysql_replication_hostgroups
mysql_replication_hostgroups
extended with a field check_type
that accepts one of these 3 values: read_only
,innodb_read_only
andsuper_read_only
.
This allows replication hostgroups to work with Aurora and setups where super_read_only
is used.
Implemented causal reads using GTID
Schema changes:
mysql_servers
table was extended with a new columngtid_port
: it specifies from which port GTIDs will be read- added column
comment
inmysql_users
table - added new table
stats
.stats_mysql_gtid_executed
that exports GTID statistics mysql_query_rules
table was extended with a new columngtid_from_hostgroup
to specify to which writer hostgroup the read should be consistent withstats_mysql_query_digest
was extended with a new columnclient_address
. If new global variablemysql-query_digests_track_hostname
is enabled,client_address
tracks the address of the client sending the request.- added new variable
mysql-binlog_reader_connect_retry_msec
to specify how often to retry to reconnect to binlog reader - added new
stats
tablemysql_errors
that collects statistics about queries and connections errors - added new table
mysql_galera_hostgroups
for native Galera support
Implemented SSL for frontend connections
- Clients can now connect to ProxySQL using SSL.
- Field
mysql_users
.use_ssl
is now enforced, and users withuse_ssl
enabled must use SSL, a blog post will follow with further details.
New Admin commands
PROXYSQL COREDUMP
: allows to generate a coredumpPROXYSQL FLUSH QUERY CACHE
: flushes the query cache
Native support for Galera Cluster
- ProxySQL 2.0 natively supports Galera Cluster with an extended configuration including multi-master and backup writer support, a blog post will follow with further details.
Security enhancements
- When possible, use
RAND_bytes()
to generate scrambles
Memory optimizations
- automatic
VACUUM
ofstats
schema - if the new global variable
mysql-query_digests_normalize_digest_text
is enabled, queries statistics storedigest_text
on a different hash table. This drastically reduce memory usage on setups with many schemas but similar queries patterns
Performance improvements
- improved the performance of
MySQL_Thread::refresh_variables()
- several optimizations in the code that generate a variety of
stats
tables - multiple improvements in the Monitor module
- traffic handled when
fast_forward=1
is now considerably faster
LDAP
- added support for LDAP, a blog post will follow with further details.
Query cache
- updating
mysql_query_rules.cache_ttl
purges cache entries - added column
mysql_query_rules
.cache_empty_result
: if disabled, empty resultsets won't be cached - added new command
PROXYSQL FLUSH QUERY CACHE
Protocol
- added support for
autocommit
=(true|false|on|off)
- added support for
SELECT CONNECTION_ID()
- handler error
2019
, when unable to change charset because unavailable on backend - implemented
clear_password
login - implemented
AuthSwitchRequest
to switch authentication method. This makes ProxySQL usable for client libraries usingcaching_sha2_password
and also allows support for the LDAP plugin
General changes
- automatically increase
RLIMIT_NOFILE
if the value 1024 is detected - do not dump on error log runtime mysql servers tables when running queries against
runtime_mysql_servers
- maximum value for
mysql_servers
.weight
is now 10000000 mysql_query_rules
.replace_pattern
has better input validation- added many status variables to improve troubleshooting
- if
mysql-query_digests_track_hostname
is enabled,stats_mysql_query_digest
tracks the hostname of the client sending the query
