cfg_deprecated

These parameters are deprecated since Tarantool version 1.7.4:

logger

Deprecated in favor of log. The parameter was only renamed, while the type, values and semantics remained intact.

logger_nonblock

Deprecated in favor of log_nonblock. The parameter was only renamed, while the type, values and semantics remained intact.

panic_on_snap_error

Deprecated in favor of force_recovery.

If there is an error while reading a snapshot file (at server instance start), abort.

Type: boolean

Default: true

Dynamic: no

panic_on_wal_error

Deprecated in favor of force_recovery.

Type: boolean

Default: true

Dynamic: yes

replication_source

Deprecated in favor of replication. The parameter was only renamed, while the type, values and semantics remained intact.

slab_alloc_arena

Deprecated in favor of memtx_memory.

How much memory Tarantool allocates to actually store tuples, in gigabytes. When the limit is reached, INSERT or UPDATE requests begin failing with error ER_MEMORY_ISSUE. While the server does not go beyond the defined limit to allocate tuples, there is additional memory used to store indexes and connection information. Depending on actual configuration and workload, Tarantool can consume up to 20% more than the limit set here.

Type: float

Default: 1.0

Dynamic: no

slab_alloc_maximal

Deprecated in favor of memtx_max_tuple_size. The parameter was only renamed, while the type, values and semantics remained intact.

slab_alloc_minimal

Deprecated in favor of memtx_min_tuple_size. The parameter was only renamed, while the type, values and semantics remained intact.

snap_dir

Deprecated in favor of memtx_dir. The parameter was only renamed, while the type, values and semantics remained intact.

snapshot_period

Deprecated in favor of checkpoint_interval. The parameter was only renamed, while the type, values and semantics remained intact.

snapshot_count

Deprecated in favor of checkpoint_count. The parameter was only renamed, while the type, values and semantics remained intact.

rows_per_wal

Deprecated in favor of wal_max_size. The parameter does not allow to properly limit size of WAL logs.

election_fencing_enabled

Deprecated in Tarantool v2.11 in favor of election_fencing_mode.

The parameter does not allow using the strict fencing mode. Setting to true is equivalent to setting the soft election_fencing_mode. Setting to false is equivalent to setting the off election_fencing_mode.

Type: boolean

Default: true

Environment variable: TT_ELECTION_FENCING_ENABLED

Dynamic: yes
