"Error decompressing zstd block: Corrupted block detected"
This error appears when I search with datamodel but this datamodel isn't accelerated and with searches with a lot of results, and I want to know how to fix it and what is the reason for that.
We solved this problem improving the server performance with more processors and RAM.
On search.log of your search, on $HOME_SPLUNK/var/run/splunk/dispatcher/ should show something like the following to know that the ZSTD is working fine:
DEBUG BlockDecompressingStream - ZSTD block header=070434
DEBUG BlockDecompressingStream - ZSTD decided we needed input_size=57478, previous_size=65536
BlockDecompressingStream - output_offset=1179648, block_size=1048576
DEBUG BlockDecompressingStream - ZSTD decompressed block, buffered=1, isize=57478, osize=131072
DEBUG SortOperator - deserializing chunk from /opt/splunk/var/run/splunk/dispatch/1568790023.15/statstmp_partition0_1568794563.543.srs.zst

You need to enable DEBUG at Server settings > Server loggins for searches...
