Vyacheslav Koptilin updated IGNITE-20564:
-----------------------------------------
Description:
*Motivation*
According to the results of IGNITE-20357 we need to refactor our node storage
configurations with the usage of new abstraction {_}storage_profile{_}.
Storage profile in general is a pair of two entities:
- storage engine type
- storage data space. It will be regions for {_}aipersist{_}, for example.
>From configuration point of view:
- Engine configurations must be still a part of separate configuration group
- Storage profiles must be a part of separate configuration root
*Implementation notes*
Example:
{code:java}
rocksDb:
flushDelayMillis: 1000
regions:
lruRegion:
cache: lru
size: 256
clockRegion:
cache: clock
size: 512
aipersist:
checkpoint:
checkpointDelayMillis: 100
regions:
segmentedRegion:
replacementMode: SEGMENTED_LRU
clockRegion:
replacementMode: CLOCK
{code}
will transform to
{code:java}
storages:
engines:
aipersist:
checkpoint:
checkpointDelayMillis: 100
rocksDb:
flushDelayMillis: 1000
profiles:
lru_rocks:
engine: rocksDb
cache: lru
size: 256
clock_rocks:
engine: rocksDb
cache: clock
size: 512
segmented_aipersist:
engine: aipersist
replacementMode: SEGMENTED_LRU
clock_aipersist:
engine: aipersist
replacementMode: CLOCK
{code}
*Definition of done*
- All storage configurations migrated to storage profiles.
