Kirill Tkalenko updated IGNITE-23283:
-------------------------------------
Description:
We need to add throwing
*org.apache.ignite.internal.metastorage.exceptions.CompactedException* for
single read methods for metastorage methods:
*
org.apache.ignite.internal.metastorage.MetaStorageManager#get(org.apache.ignite.internal.lang.ByteArray,
long)
*
org.apache.ignite.internal.metastorage.MetaStorageManager#getLocally(org.apache.ignite.internal.lang.ByteArray,
long)
*
org.apache.ignite.internal.metastorage.impl.MetaStorageService#get(org.apache.ignite.internal.lang.ByteArray,
long)
Such methods will throw a {*}CompactedException{*}:
# The key exists and the requested revision of the key has already been
compacted.
# The key does not exist and the requested revision has already been compacted
in the metastorage.
Let's look at examples.
Let's say there is a key "foo" in the metastorage with a single revision 3.
The metastorage has finished compacting to revision 5.
The key "bar" has never been in the metastorage.
Let's look at some examples:
# MetaStorageManager#get(“foo”, 1) - a *CompactedException* will be thrown.
# MetaStorageManager#get(“foo”, 2) - a *CompactedException* will be thrown.
# MetaStorageManager#get(“foo”, 3) - will return a single value with revision
3.
# MetaStorageManager#get(“foo”, 5) - will return a single value with revision
3.
# MetaStorageManager#get(“foo”, 6) - will return a single value with revision
3.
# MetaStorageManager#get(“bar”, 1) - a *CompactedException* will be thrown.
# MetaStorageManager#get(“bar”, 5) - a *CompactedException* will be thrown.
# MetaStorageManager#get(“foo”, 6) - will return an empty value.
