Want to change key structure

I have a large HBase table (~10 TB) that has an existing key structure. Based on some recent analysis, the key structure is causing performance problems for our current query load. I would like to re-write the table with a new key structure that performs substantially better. What is the best way

Have you looked at FuzzyRowFilter ? Cheers On Mon, Feb 19, 2018 at 8:00 AM, kitex101 wrote: > I have key design like:byte[] rowKey = > =Bytes.add(Bytes.toBytes("3"),Bytes.toBytes(customer_id), > Bytes.toBytes(timestamp)); > customer_id and timestamp are long type. As

I mentioned the method accepting int because of the example in your first email. I verified in Eclipse that Bytes.toBytes(98) would end up in that method. I understand in your application data is typed as long. However that is not shown in your previous example. On Sat, Feb 17, 2018 at 9:00

Query data like opentsdb

I have key design like:byte[] rowKey = =Bytes.add(Bytes.toBytes("3"),Bytes.toBytes(customer_id),Bytes.toBytes(timestamp)); customer_id and timestamp are long type. As opentsdb uses:[…]I would like to filter my key by customer_id and timestamp. How do I do that?I have tried using prefixfilter.

Re: Trying To Understand BucketCache Evictions In HBase 1.3.1

Hi Seems you have write ops happening as you mentioned abt minor compactions. When the compaction happens, the compacted file's blocks will get evicted. Whatever be the value of 'hbase.rs.evictblocksonclose'. This config comes to play when the Store is closed. Means the region
