-----------------------------------------
We can use the equals operator to achieve the required filtering, Some samples
below:
{code:java}
$ ozone debug ldb --db=ZDump/bigDB/container.db scan --cf=block_data
--filter="blockID.containerBlockID.containerID:equals:2" --fields="blockID" -l=3
{ "2|113750153625600002": {
"blockID" : {
"containerBlockID" : {
"containerID" : 2,
"localID" : 113750153625600002
},
"blockCommitSequenceId" : 6
}
}
, "2|113750153625600005": {
"blockID" : {
"containerBlockID" : {
"containerID" : 2,
"localID" : 113750153625600005
},
"blockCommitSequenceId" : 14
}
}
, "2|113750153625600009": {
"blockID" : {
"containerBlockID" : {
"containerID" : 2,
"localID" : 113750153625600009
},
"blockCommitSequenceId" : 22
}
}
$ ozone debug ldb --db=/Users/tejaskriya.madhan/ZDump/bigDB/container.db scan
--cf=block_data
--filter="blockID.containerBlockID.localID:equals:113750153625600002"
--fields="blockID"
{ "2|113750153625600002": {
"blockID" : {
"containerBlockID" : {
"containerID" : 2,
"localID" : 113750153625600002
},
"blockCommitSequenceId" : 6
}
}
}{code}
